Tsingtek low temperature lcd display

For not using polysilicon Tsingtek 16x1 lcd display technology vendors, the main focus is to improve the improved backlight brightness and color performance. In this area , CCFL cold cathode fluorescent lamp is absolutely mainstream , even though the technology for many years, has been very mature, but as time goes on , it becomes increasingly obvious flaws . The tubular light sources are cold cathode fluorescent lamp , in order to evenly distribute the light in each of the liquid-crystal panel requires the use of a reflector comprising light guide plate , an optical diffusion sheet , a prism sheet auxiliary component composed of the entire system is also called " backlight module . " But even so , the conventional low temperature lcd display to achieve uniform brightness is also more difficult , coupled with complex structure, difficult to achieve thin backlight module thickness . More importantly, the color gamut cold cathode fluorescent lamp is relatively narrow , resulting in almost all LCD monitors are unable to reach standard flat Adobe RGB color gamut of printing , while the ordinary CRT monitor and a small LCD to achieve high SRGB standards , but has a considerable part of the recent mainstream LCD display products for SRGB standards provide support. In the professional mapping applications, the operator often need a wide gamut of tone deployment of existing LCD monitors because the narrow gamut , are often unable to guarantee the color accuracy. In addition, the cold cathode fluorescent lamp life is not long , many LCD screen after a few years in the use of the product will be yellow , brightness significantly low , although in theory you can replace the lamp LCD display to enhance the quality , but the general service rarely provide this service, not many users are willing to take such a risk. Therefore , the best working condition LCD is also only a few years .

Serial Lcd Display Module

When the temperature decreases , the threshold voltage of theTsingtek china lcd color lcd display module will rise, increasing the drive voltage of graphic lcd display module , liquid crystal display can be realized at a low temperature . The main components of this method that the temperature sensor and adjustable output voltage and the drive voltage of the liquid crystal Serial Lcd Display Module according to the ambient temperature to allow the display to achieve the display at a low temperature , this method can make the liquid crystal display of the operating temperature range of -20 ℃ ~ +50 ℃. But the drive voltage can not raise unlimited ended , when the drive voltage is increased to a certain extent, the display contrast will be significantly decreased , resulting in a black screen monitor can not even use .

Cryogenic liquid crystal display

Cryogenic liquid crystal display monitor implementation of
Tsingtek china lcd Serial Lcd Display Module with low power consumption , high definition, long life, small size, light weight, good optical properties and other characteristics, is ideal for display devices , widely used in a variety of instruments .
graphic lcd display module is a passive display , which itself does not emit light, can only rely on ambient light to display . It is just a very small energy patterns or characters can be displayed . Because of the low power consumption and miniaturization of the LCD to become a better display. The liquid crystal display is a liquid crystal material used in both liquid and solid organics dual nature , its structure is generally rod-like liquid crystal cell are arranged in parallel , but in the arrangement direction of the electric field change .

How to solve the LED display for low impact

Recently , the temperature also plummeted , for us in terms of outdoor installation , the same difficulties, many of my colleagues hands are frostbitten , but the face of bad weather , we can only look for good weather to step up construction . In dealing with Shanxi LED display, encountered such problems, here want to record their own practices , as we better grasp , handling, outdoor Tsingtek china lcd graphic lcd display module to help.

A , tight , heavy tasks

Estimation of view, there are two weeks came to Shanxi , because the mountainous region located in Shanxi , harsh environment , cold mountain climate, our installation and maintenance personnel is facing a severe test , no way , time , heavy task , only stepping up construction .

Second, the difficulties encountered

We all know that in some cold countries and regions, mostly perennial temperature below 0 ℃, the night even below -30 ℃, LED display in this area , when the ambient temperature is too low , it will not cause the power is turned on the display success. In addition , the composition of the low temperature lcd display a variety of materials because of their different thermal expansion coefficients of variation of its physical size is inconsistent, prone to large gaps between the modules or even squeeze bumps burst , causing the low temperature lcd display waterproof dust failure and apparent mosaic phenomenon . These are the problems we face , we need to resolve one by one .

Third, the solution

1 using low power

End : Japan TDK Power ( ultra-low temperature -40 ℃, conventional -30 ℃)

Taiwan Ming Wei Power ( ultra-low temperature -20 ℃, conventional -10 ℃),

In the end there : Chinese Year of the power ( conventional -10 ℃, low temperature -25 ℃, ultra-low temperature -35 ℃)

Chinese star power ( conventional -40 ℃)

Practice has proved that low power , can also play a good frost, Gwen effect. Here we used the last one.

(2) using anti- cold box

You might ask , cold boxes , there is this ? In fact , the box is made ​​of high quality steel plate, hot -dip zinc cabinet overall process, the cabinet process, the metal surface cleaning sandblasting rust play a role ; oxide coating on the metal surface zinc treatment to prevent surface oxidation and corrosion ; surface paint or grease spraying anti-acid , acid rain, fog effectively prevent erosion .

In general , we need to continue to follow up on the progress of the installation , which in actual maintenance for technical personnel , need more knowledge to understand the job that way .

Well, I hope this trip can be successfully completed in Shanxi , but also want to be able to give some help colleagues , after all, outside year round , but also very difficult for .

Implementation and the advantages and disadvantages wide temperature display

Wide temperature display commonly used for cooking is the use of low-temperature heating of the way , but this way there will be a liquid crystal heating outflow phenomenon or restore some difficulties when Aguri course , there are other studies of individual heating key points . Overall, point by point the entire surface heating and heating in two ways. Such displays the overall power consumption will increase 4-6 times . Such as 15-inch  Tsingtek china lcd low temperature lcd display monitor at room temperature (22 ℃) under power is 20ww, power consumption in low-temperature environment (-40 ℃) for :90-120w, this approach is the heating method .

There is another way to achieve wide temperature : increase the brightness of the low temperature lcd display screen . Increase the backlight lamp , through the development of a special high-pressure section ( to produce the starting voltage 2000v-3000v ) in a low temperature environment (-40 ℃) lit backlight lamp , a huge amount of heat generated due to make an LCD backlight lamp warming, which ways to serve two purposes, namely to solve the problem of low temperature liquid crystals , but also solve the problem of the sun visible . In this way referred to brightening way .

Research and application of excessive heat and brightening the way that these two approaches , there are many quality problems : ① Both methods have increased the number of accessories, reduced reliability . ② assembly is too much trouble , likely to cause defects , high defect rate . ③ impact device , the ability to decrease vibration . ④ In the aging test, found in the environment of 50 ℃ aging fast, the acceleration was increased , especially brightening way , the normal life of only 1/ 10 .

To solve these problems , a series of product innovation and technology development . Developed a world- leading lcd graphic display modules technology , high temperature applications , solve the above problem. New products do not need to be heated brightening neither can work properly at low temperatures. The basic principle is as follows : LCD and no freezing at low temperatures (-40 ℃) or send bio- state transition , either heating or otherwise brightening methods are not working , so we thought of using software to correct its electrical properties manner drift . Trying to trigger the liquid crystal at a low temperature work . This requires the driver to adjust the LCD timing and so on. Through a lot of trial and extensive research applications, this technology has been very mature , regardless of how changes in ambient temperature , by widening the trigger timing and match the appropriate driver can ensure the normal operation of the liquid crystal . As this technology has been leading in the world, so sales have doubled every year.

LED backlight technology

For not using polysiliconTsingtek china lcd color lcd display module technology vendors, the main focus is to improve the improved backlight brightness and color performance. In this area , CCFL cold cathode fluorescent lamp is absolutely mainstream , even though the technology for many years, has been very mature, but as time goes on , it becomes increasingly obvious flaws . The tubular light sources are cold cathode fluorescent lamp , in order to evenly distribute the light in each of the liquid-crystal panel requires the use of a reflector comprising light guide plate , an optical diffusion sheet , a prism sheet auxiliary component composed of the entire system is also called " backlight module . " But even so , the conventional type graphic lcd display module to achieve uniform brightness is also more difficult , coupled with complex structure, difficult to achieve thin backlight module thickness . More importantly, the color gamut cold cathode fluorescent lamp is relatively narrow , resulting in almost all LCD monitors are unable to reach standard flat Adobe RGB color gamut of printing , while the ordinary CRT monitor and a small LCD to achieve high SRGB standards , but has a considerable part of the recent mainstream Serial Lcd Display Module products for SRGB standards provide support. In the professional mapping applications, the operator often need a wide gamut of tone deployment of existing LCD monitors because the narrow gamut , are often unable to guarantee the color accuracy. In addition, the cold cathode fluorescent lamp life is not long , many LCD screen after a few years in the use of the product will be yellow , brightness significantly low , although in theory you can replace the lamp LCD display to enhance the quality , but the general service rarely provide this service, not many users are willing to take such a risk. Therefore , the best working condition LCD is also only a few years .

High-temperature polysilicon technology

Low-temperature polysilicon technology and high-temperature polysilicon is a corresponding Tsingtek china lcd graphic lcd display module concept we have previously mentioned , the use of high-temperature polysilicon quartz glass as the substrate temperature , and the high purity quartz glass are very expensive, and very difficult to achieve a larger size , which determines the temperature polysilicon technology can not as a display of the computer. However, large-screen HDTV color lcd display module Projection TV (Large-screen projection TV) in areas such as high-temperature polysilicon technology found in commercial / home front projector (Front projectors), his own position , especially in the three-piece LCD projection system, high temperature polysilicon technology in the field of global market share as high as 55 %.

Low-temperature polysilicon : LCD rising star

See the great advantages of low-temperature polysiliconTsingtek china lcd low temperature lcd display exist , all the major graphic lcd display module manufacturers have invested heavily in the technology practical research . Plagued the industry 's first problem is that , at an early stage , low-temperature polysilicon panels are very expensive , when most people think of polysilicon industry is not suitable for the manufacture of computer technology used in large-size Serial Lcd Display Module monitor, the market will focus on the major cell phone , PDA, digital cameras and other handheld digital products, while the later development of the market will move forward in accordance with this context .

TV profit era : the transformation of Japanese companies gone

Along with numerous Japanese companies suffered the pain of loss , a loss of television services has always been to get rid of Japanese electronics giants to become the first choice , and the pace is accelerating. During this period , Toshiba Dalian factory closed down just a microcosm. Television as a stepping stone to the front of the mall Japanese company , back in the mall trying to erase them to make "home company" positioning, diversification has become throughout the selection . Today, out of home appliance manufacturing Japanese companies really gone ?

Negative television services to shorten

" This is just a 900 factories , shopping malls and goods supplied only in Japan and this work is actually very small , there is no impact on the Chinese mall foundation ." December 5 , the person in charge told reporters Toshiba confirmed the Dalian factory will strike and abort operations audio .

Previously, Toshiba China announced on its official website , declaring the primary supply of TV production base in Japan mall Dalian Toshiba Television Co., Ltd. will be discontinued at the end of year 12 and suspended operations.

It is now more than a month , the second cut Toshiba LCD temperature compensation TV production bases overseas . Toshiba declared October 29 , will be located in Poland 's premier shopping malls in Europe supply LCD TV production base , with $ 25 million offer to sell the foundry giant Taiwan Compal . It is reported that trading will end next year in January . Dalian plant closure was not a sudden resolution , Toshiba has already declared the program to shut down three factories in the two overseas television , and later closed , Toshiba overseas will also be the only one in Indonesia LCD character display production base .

TV plant remains closed intent to surplus. Toshiba showed that after adjustment the China production base will further cut fixed costs in order to achieve a surplus in 2013 to complete the second half of the policy . In addition, Toshiba also plan before the end of the fiscal year , television affairs department will lay off 50 percent . However, Toshiba does not think the move from a continuous weight loss television services , television services is conducting shortening . Toshiba , the official told reporters focused on the global LCD TV sales now are cutting , Toshiba based solely on changes in the mall , combined with the affairs of the impression , not shortened.

But the mall has changed not only in Europe , Toshiba TVs sold in Japan Hongo also suffered arrest. May 8 this year , Toshiba released a statement of fiscal year 2012 , during which television services presents a $ 500 million loss. The cause of loss of earnings due to the Japanese domestic TV and PC Mall constantly narrowed , resulting in 2012 showed a significant decline in the amount of the sale . In this year 's semi-annual report just released soon , because Toshiba touchpanel LCD modulein North America showed an intermediate rendering reduce, TV and PC Affairs has presented nearly 10 billion yen ( about 098 million U.S. dollars ) of loss.

Where the Japanese companies

  Television as a stepping stone to the front of the mall Japanese company , back in the mall trying to erase them to make "home company" positioning, diversification has become over the selection of these tycoons . "Toshiba actually can not be regarded as an appliance company . Toshiba has the infrastructure , electronic components , digital and home appliances four transactions in China , while the share of household appliances in global affairs that is, about 10% ." Toshiba relevant person in charge told reporters showed . Toshiba 2012 earnings show , the total revenue of 5.8003 trillion yen , while revenue as long as the appliance 591.5 billion yen , indeed only about one percent. Toshiba Dalian factory shut down together , declaring to $ 35 million to buy a U.S. manufacturer of solid-state drives OCZ; lighting produced headquartered in Fuzhou Mawei Toshiba invested 180 million yuan in China beefing currently under construction with an estimated production next year ; the Dalian plant on vacant factories and land , Toshiba showed the thinking used medical equipment production base and industrial motors and other commodities. Sony Electronics category entrenched spend too long to extend from one transaction to the upstream and downstream industry chain , including content creators , mobile , impressions , three games to become the center of the electronic transaction category. In fiscal year 2013 semi-annual report , the smart phone has become an important reason for Sony to sell to increase revenue. Sharp released an interim operational plan 2013 to 2015 , the health care , robotics , smart car shelter , water and air relief works and teaching areas , became determined to carry out the scope of the new .

Zhuo Saijun told reporters: "Japanese companies to cut unnecessary production costs is a good thing , it will help them to have an advantage in the areas of resource gathering ."

TV has now entered the era of meager profit , strategic operations of Japanese companies are now increasingly lightweight property completely , but is busy setting up factories abroad, China's color TV giants , is also the face of the arrival of this day ?

Mall marketing rules is difficult to form a consistent LCD-screen

LCD screen display is difficult to form a consistent shopping mall marketing rules in the short term is relatively stitching unit with their own brands , the majority of the large-screen display industry " fought " for many years , in the contacts , channels, more experience and R & D capabilities excellent . These companies , such as GQY can rely on their own brand influence to promote the development of LCD modules splicing products, but it can provide sophisticated system solutions , but also one of the advantages to attract high-end customers . However, such manufacturers integrators , there are many new brand , or " small" brand within the industry. Such vendors product strategy , while having the flexibility and autonomy of the product system , but facing a " brand" weak level of competition .
    In order to create an integrated and professional integrators based LCD supplier splicing camp competition is the length of each game. This law also determines the marketing LCD display market is difficult to form the short-term unity. Character LCD module splicing combined network of product marketing for the attention of factors , the importance of local service capacity , domestic manufacturers of existing regional distribution of the hills , the contest between the different types of vendors will be in the long term from .
    Including large brands, such as Samsung , Sharp , LG, Vtron, GQY within the country , such as the orientation tends to target marketing and brand value , a fundamental decision will be the key point of the liquid crystal display market makers to pattern .

With the depth of information to strengthen the LCD screen

Followed by information technology to enhance the depth of the LCD -screen innovation skills feel the burn
From the quote , the same as the next single large scale cf than LCD splicing screen appear to be expensive, but the effect is not apparent contrast . For example, for window shopping sideways exhibition show , to show the relative ratio LCD supplier Video Wall , and commercial large-screen to show the role of the monomer may be very good number . It can be placed directly on the ground , to show a more sensitive role . Coupled with the power of endogenous character LCDs splicing product itself constituted solely in the mall low threshold and low commodity quotes on two levels , with the "high tech" industries do not fit the position . Additionally, the current appears to follow the commercial use of goods continue to extend , deepen the big screen now show commercial transportation , media, advertising , finance, teaching and other occupations, the whole industry chain is becoming a huge industry and constantly improve the value , the electronic information industry has become with strategically important areas . Memories of this year's audio-visual exhibition , commercial vendors will show points gathered in force traffic security , commercial show , hotel and retail, teaching and training and other aspects. So , no matter from the viewpoint of skills remains a commodity point of view , or from a more conceptual future use to show respect, seem to imply that all the manufacturers on suppliers significantly mall launched a " vessel ."
Followed by information technology to enhance the depth , the difference needs to show the increasingly widespread use of high-definition intelligent information engineering increasing use their skills on the LCD splicing innovation increasingly feel the burn . LCD module manufacturer splicing is necessary to disconnect the advantage by virtue of occupying quote positioning mall , improve skills , serve , using a multi-dimensional plans to malls , through innovative skills to win mall. The large screen to show after all the high-end commercial use appearing , there is no lack of Vewell , LG, Sharp, ViewSonic major manufacturers do this pillar , trust sales fell just short-term temporary !

LCD module Precautions

A : protective film
LCD module surface affixed with a protective film to prevent the display surface contamination during assembly , before the end of the whole assembly must not be thrown off .
Two: to prevent electrostatic
LCD module Embedded LCD driver chip is massive COMS circuit can easily be electrostatic breakdown , while the electrostatic breakdown is irreparable , so in operation , assembly and use should prevent static electricity , it must be noted :
1 : You can not cheat hand free to touch LCD driver chip and circuit board modules , if you must contact must take anti-static wrist strap , anti-static finger sets / gloves, best to wear anti-static clothing , so the human body is well grounded.
2 : table, iron and tools well grounded .
3 : keep the humidity in the workplace than RH60%.

3 : Do not use acid flux .
   4 : Repeat soldering no more than three times, and each repetition interval of five minutes .
5 : Wash thoroughly after soldering , welding to prevent short circuits and signal interference , be careful not to spill the cleaning liquid onto the backlight.
Four: Installed
Not secretly change the LCD module supplier. Such as: change parts , change the circuit , twisting iron frame foot , demolition of PCB board processing . The above behavior caused LCD module does not display all do not give maintenance , except with the consent of our staff only .
Five: Testing
1 : LCD module and microcontroller connection refer to " wiring diagram ." Note the positive and negative polarity power supply can not be wrong , or cause overcurrent, overvoltage, burned chip circuit.
2 : After the correct wiring, began testing the liquid crystal display module , first open the logic power , then turn LCD drive power supply module ; time off , first turn off the LCD drive power supply module , and then turn off the logic supply at the positive supply. after stable access to the input signal level , such as the input signal level before and after disconnecting the power supply stable or may damage the China LCD display module IC.
3 : LCD display module with temperature changes and changes accordingly. When the ambient temperature exceeds the operating temperature of the liquid crystal display module , a liquid crystal state disappeared into the liquid , black display , this time must not be energized, and so reduce the temperature of self-healing ; Conversely , low temperature , ice crystals begin crystal flower , causing permanent damage. Another long-term storage at extreme temperatures or by vibration, shock , LCD will produce bubbles.
This is applied to the liquid crystal display module temperature compensation circuit reasons, or add an external potentiometer to adjust the contrast.
4: The LCD module can output VOP too , will affect the display, but also shorten the life of the module. Please refer to the correct voltage VOP each product specification.
Five: Storage
1 : Keep the original packaging.
2 : Wide Temperature save in the range of -30 ℃ ~ +80 ℃; ordinary temperature type stored in the range of -10 ℃ ~ +60 ℃.
3 : Put the dark, to avoid glare .
4 : You can not put anything on the surface pressure .
5 : Avoid storage in extreme temperature / humidity conditions.

China Touch Screen Industry Development Overview

Changes in a country's stock market reflects how the current situation of national economic development . Currently , the touch screen is one of the most popular since the intelligent terminal market concerns of the industry sector , Recently touchscreen stocks continued strong upward shocks , Fenghua Hi-Tech , Deren Electronic , East China Science and Technology , Hanwang Technology , Changjiang Electronics Technology , Yu Shun Electronics , Sanan Optoelectronics and other gains are great.
  Smart phone market will continue to grow next year , but will not grow as fast as in previous years . For example , in 2012 in mainland China smart phone market is growing three times this year, roughly doubled , next year can be maintained above 30% , there are still double-digit growth. Tablet PC growth rate will be higher , because of its large scale is not the phone , as a relatively new market , global growth next year may reach 70% to 80%. Plus automotive electronics, medical , sports , home appliances , and other communications applications also will be used to touch , never use the touch areas are being converted , these are " from scratch ," the opportunity to drive the entire industry sustainable development.
  Due to a large number of Chinese fonts LCD module mainland market capacity , consumption levels , many manufacturers have their own market segments. At present, resistive touch screen products such as large Lu Fuyang photovoltaic manufacturers , Huayi circuit , Norstar display , Huang Ze photoelectric deep more optoelectronics, electronics Watson , also working in the middle of the chain touch screen, touch panel manufacturing expansion, try to keep their share of the market. The CSG , Leybold Tech , Pegasus A touch screen and other mainstream manufacturers of OGS touch screen development, to ensure its leading position in the touch screen market.
  Currently, the touch screen there are 24 kinds of application categories , now smart phones, tablet PCs and laptops are the main fields of application. With the increase of the size of the touch screen market demand for large-size touch screen market has unlimited potential , which large multi-touch terminal market computer monitors, television began to appear , the mainland manufacturers have developed capacitive touch screen technology. Capacitive touch screen with high transmittance, durability and support for multi-touch features , a better future market prospects.

  On the other hand , the Embedded LCD display industry Gone are the days of high profits . Jin increasingly fierce competition , touch giants also have to adjust the industrial structure to deal with. Recently, due to the increased competition in the industry to opt out of animal husbandry East photoelectric become the focus of attention . In addition , the domestic small and medium sized touch screen factory closures also illustrates the touch industry has quietly entered a period of consolidation .

MOS tube drive lcd module

Compared with the bipolar transistor is generally believed that the MOS conduction current is not required , as long as the GS voltage is higher than a certain value , it. This is very easy to do , but we also need to speed.
Can be seen in the structure of the MOS transistor , parasitic capacitance between the GS, GD, and the driving MOS transistor , in fact, is to charge and discharge the capacitor .Tsingtek TFT LCD Displays Charging the capacitor requires a current because the capacitor to charge the capacitor can be instantly seen as a short circuit, so the instantaneous current will be relatively large . Select / design MOS tube drive the first to note is to provide instantaneous short circuit current size.
Note that the second , NMOS commonly used in high-side driver , need to be turned on when the gate voltage is greater than the source voltage. The high-side driver MOS transistor is turned on when the source voltage and the drain voltage (VCC) the same , so when the gate voltage than VCC big 4V or 10V. If the same system , to get larger than the VCC voltage , the boost circuit is necessary to specifically . Many motor drives are integrated charge pump, it should be noted that the choice of suitable external capacitor to get enough of the short-circuit current to drive the MOS transistor .
Said above 4V and 10V is a common turn-on voltage MOS tube , of course, need to have a certain margin design. And the higher the voltage , the faster conduction , conduction resistance is smaller. Now there are smaller turn-on voltage MOS works in different areas , but in 12V automotive electronic systems, general 4V conduction suffice.
MOS tube drive circuit and loss , you can refer to Microchip 's AN799MatchingMOSFETDriverstoMOSFETs. About it in detail ,
MOS tube application circuit
MOS transistor is the most significant characteristic of a good switching characteristic Tsingtek lcd display 2x16, which is widely used in the electronic switching circuit needed , such as switching power supplies and the common drive motor , there are lighting dimming .

Display principle LCDTFT DID lcd module screen features and analytical

LCD (LiquidCrystal) that liquid crystals , both as a liquid ( energy flow ) and like crystals ( optical properties of crystals ) of the material. Alignment of liquid crystal molecules have a certain order and arrangement of liquid crystal molecules will change under the influence of external electric field, thus affecting its optical properties.
LCD (LiquidCrystalDisplay, abbreviated LCD) is a thin glass plate constituted of two parallel , the distance between the two glass sheets is very small, is filled with liquid crystal is divided into small units . LCD panel itself does not light , it is through the LCD backlight to make the Tsingtek Character LCD Display screen lights up . Advantages of LCD screen is small, light weight , large area display , image stabilization, no radiation, low power consumption and environmental protection features . Compared with CRT monitors, LCD monitors power consumption CRT only 1/3 of the thickness of only 1 / 8 , weighs less than 1 /3 of the space savings of more than 60 %.
TFT LCD (Thin-FilmTransistor), abbreviation thin film transistor liquid crystal screen is the top material belonging to an active matrix type liquid crystal screen , the back has a special lamp, can be " actively " on each individual pixel on the screen control , which is what we often say that the active matrix TFT, it reacts faster , viewing angle , color saturation. Due to the arrangement of TFT LCD screen has a memory , so no restitution immediately after the current disappears , effectively improve the ability to play a dynamic picture .
What is DIDTFTLCD?
DID (DigitalIntelligenceDisplay) Tsingtek TFT LCD Module is dedicated LCD screen. It is based on the technical requirements used in security , radio and television , medical, industrial , and public areas such as media, publishing professional monitors designed and produced , following the NB, PC and fourth generation of LCD TV products . Its excellent display performance , has been recognized as the most high-end, the best LCD monitor screen.

On the camera's LCD screen

1 you see may not be what you get

Many of my friends like to shoot in RAW format . But in fact when you're shooting in the LCD view when the LCD screen is presented JPEG preview . So , if you see the color, contrast and exposure are not you ask it, do not panic , the file you are actually shooting will contain more data to be adjusted on a computer after the operation .

In addition , we found that the image displayed on the LCD screen than your final printed photos more vivid in color ,Tsingtek OLED modules brightness, stronger, clearer images and more . The reason is that the small size of the LCD screen or backlight illumination , so some exposure and focus on other issues tend not to be perceived by the user.

2 You can zoom through the LCD screen to find the problem

Whether it is a digital DC or digital SLR , its LCD screen can be used to enlarge your picture taken . By enlarging the picture, you can focus pictures taken timely query whether Indeed, the use of depth of field is in place .

3 composition functions can help you

Squares line is almost every digital camera has a function. Squares line can help you through the LCD monitor to compose the shot . ( Digital SLR camera in LIVE VIEW can be presented with the next viewfinder ) .

Using this grid, allows you to take pictures when the composition to ensure the horizon level, to remind myself not to be placed in the middle of the main shooting screen , or check the optimum location of the building trapezoidal distortion and so on.

4 shows a histogram parameters such information

Exposure, brightness histogram from dark to light transition tables and other information have some basic ideas for people photography is very necessary information. After early photographs , watch the histogram trend that lets you know where the photo had burst ( burst over the area will flash to warn ) in order to allow you to make adjustments before the next shot inside the machine .

Many cameras have an independent three-color RGB graphics table , this set of graphical information can help you see in the picture color performance degree . You can find very quickly lost picture is a particular color detail .

Proper use of color histogram lets you photograph in black and white images look richer detail . For example, you shoot red roses and red channel histogram shows that you do not have access to clean moist histogram trend lines , then your performance is certainly lack the red details .

5 By the late Tsingtek COG LCD Display screen image

Now, many digital cameras are built in the latter part of the organic function , although the effect is really simple but very good. You can choose a different color style , and then through the LCD preview.

In addition, the machine also has a lot of camera cropping, and some simple beauty effect. These can preview and save your favorite proofs under the LCD screen .

Buy a LED LCD celebration

Spring will come, and a larger , clearer, especially on television excellence dynamic definition naturally become indispensable stocking purchase order items . And with the LED LCD TV hot , many consumers face an array of LED LCD TV products, often at a loss . So how can buy roses TV ?

Tips to buy one: see picture

HD LCD TV is good or bad , mainly due to the following factors: LCD panel , contrast, refresh frequency.

Said first panel . Current mainstream LCD panel is divided into two kinds of hard- and soft-screen , such as LG Display IPS hard screen is horizontal arrangement of liquid crystal molecules in parallel with the panel in response speed , uniformity of better than soft screen .

Besides the contrast. The higher the contrast ratio , the picture is even more bright white , black, more dark , that is, its color display richer . Contrast like LG some television can reach 3000000:1 , this picture will be more structured , details also performed more delicate.

Finally, the screen refresh rate. Smearing the LCD TV has been criticized for many manufacturers launch high refresh rate , such as the SL90 's 100Hz screen refresh rate , whether it is watching sports or playing sports games , all with ease.
