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.
Optional Skills II : Look signal
TV election goes , it is better signal reception is good. With high-definition LED TV , to see high-definition programs, such as "HD Spring Festival" , but also a high-definition signal for the job .
In the optional LED LCD television, digital television depends on the function of this product are complete , such as whether to receive " terrestrial digital signal," support " HD programming card insertion " and so on .
Optional Skills III : Look Appearance
If the home has a stylish design with a slim LED Tsingtek Graphic LCD
Module TV , both decorate the home, but also enhance the taste. Even without power , the people will surely win acclaim . For example, LG SL90 unique frame design , using a separate texture with thin glass mirror panels, without the slightest gap and margins , creating a unique extension of boundless beauty .
Optional Four Skills : see additional features
With the rapid development of science and technology , TV is not just TV , it should be a monitor , a video game , or even a home entertainment center.
In addition , a wireless connection with Bluetooth mobile phones, computers , MP4 and other digital devices , viewing pictures , videos and music on your TV , so the TV can thoroughly into a family entertainment center. In addition, the late night TV show to watch when you can still wear a Bluetooth headset , does not affect the family rest, is an accessory worth its user-friendly features and optional LED LCD TV brings an indispensable consideration when standard .
Overall, pre-holiday buy LED Tsingtek low
temperature lcd display TV is a technology live . Panel to take into account not only the type of the product itself is directly related to the performance , appearance, function and so on, but also comprehensive technical strength and market performance analysis vendors. The slightest mistake will inevitably fall into the trap of propaganda.

Shot ultra-stable hard-screen LCD TV is king
Today's flat panel TV market turns out to be squandering charming eyes . Not only in terms of price , quality , performance is fairly mature traditional LCD TVs are very active, and accelerate the adoption of LED LCD TVs and 3D TVs also debut should not be underestimated . So for consumers, how do we buy into a versatile products?
LCD TV panels accounted for more than 70% of the cost , is the core component of LCD TVs. Notably , the panel on the market are "hard screen" and "soft screen " points. Soft -screen liquid crystal molecules recovery is slow , the screen is unstable. In contrast, hard screen has a clear advantage : When the touch , no " Watermark " phenomenon. Even when subjected to external forces beating and shaking , it will not interfere with a hard screen showing a smooth, clear picture. For this reason , IPS hard screen technology also has ultra-stable hard screen , and " touch the selected hard screen " LCD TV selection method has also been widely used.
LED TVs are hot at that time , it has a stylish ultra-thin , fine quality , green energy-saving features, is the perfect choice for many consumers eyes. However , note that , LED LCD TV market is divided into direct type and edge-lit . The difference is that side- advantage in the slim design and cost , but also the most widely used applications ; rather direct style is more concerned about the quality of user choice. Also , buy a high- quality LED LCD TV screen to distinguish between hard and soft .Graphic LCD Display As the molecular conversion speed hard-screen LCD screen 10 times faster than the soft , so when displaying fast motion picture , better able to ensure a clear , smooth and realistic effects .
For in the initial stage of 3D TV , the general view is that the industry , 3D TV on the LCD screen of the requirements will be more stringent than 2D TV. Because the 3D TV technology is relying on the principle of super-fast screen refresh rate and shutter glasses fit , so that the two vice complete picture formed at different times of persistence visual overlay. For this reason , many manufacturers have chosen the response speed of the liquid crystal molecules advantage of IPS hard screen panel. With Trumotion480Hz technology , 3D realization of a second screen is refreshed 480 times , and through the " flashing light " technology compatible , to minimize the result of his eyes " about interference " occurred " ghosting and dizziness ," and so on. Therefore, in the 3D TV can withstand a higher price , the one based on 3D TVs IPS hard screen technology will become the first choice .
Bluntly "LCD TV screen is the pick ! ", Although somewhat definitely speaks these words , but considering the merits of the Serial Lcd Display Module and image quality for LCD TVs have a decisive impact on the election -screen LCD TV really is purchase of a key ring .

CCFL LCD backlight Analysis of strengths and weaknesses
Most LCD monitors on the market are based on CCFL (cold cathode fluorescent lamp ) backlight. CCFL backlight design are mainly two: " side-in " and " straight sets " type , but because of the side- by optical light guide design allows high attrition rates , thereby allowing the backlight brightness of the subject , the brightness of the larger panel size lower , in general, when the liquid crystal panel size over 15 inches , the backlight brightness will be significantly reduced. So we use at home are usually large-size LCD Teluk style .
Teluk type CCFL backlight module does not require a light guide plate , breakage problems are more dull , so I do not need the brightness enhancement film , especially a minority brightness enhancement film industry's patented technology , expensive, Telok style guide can be omitted brightness enhancement film and the optical plate , the cost can be significantly reduced.
But here and there is a problem , the use of Teluk type CCFL backlight LCD, panel size larger the proportion of the cost of its share of the higher backlight module , there was statistical point out that the same is to use straight sets type CCFL backlight module , when 15 inches backlight module cost only 23 % of the total , but it increased to 30 inches by 37% , and the estimate to 57 inches , backlight module cost share will reach 50% . So, Teluk type CCFL backlight only suitable for use in 30 inches or so medium-sized LCD, is not suitable for use in the design of a larger area .OLED Display Meanwhile , CCFL is the use of mercury to produce the gas discharge lighting, although the RoHS EU entered into , as long as "Mercury " dose below standard still acceptable , but no one can guarantee the future is likely to raise the standard to zero content ( do not allow use ) , then CCFL will not be used, or be diverted to non-mercury type CCFL.
Even non-mercury type CCFL technically feasible, but is still confined CCFL light tube of gas-discharge electron illumination , light tubes resistant to external force is limited by the resistance , the larger the collision will cause light pipe rupture, so the lighting failure. And in order to enhance the brightness of the screen , you must increase the number of fluorescent tubes , and then the optical density of the light pipe arrangement is too large will have a huge amount of heat , which will heat the liquid crystal forming a great challenge. Therefore, in order to ensure the heat, the only viable solution is to increase the volume of the liquid crystal.
Incidentally that the use of large -inch CCFL lcd module TV on the number of fluorescent tubes , light pipe length must also be increased due to the number of inches and growth, but longer CCFL light tube with both ends of the middle of the light pipe will prone to brightness and color MURA MURA problems , thereby affecting all of the backlight light , in order to continue to maintain the light are , you must spend to enhance light diffusion film have degrees, but the proliferation of film will bring light transmittance of breakage , reducing the brightness , the results had to reduce the brightness to increase the number of the light pipe to the reinforcing way , but the previously described : the light pipe will increase the heat difficult to design , to increase the thickness of the backlight module , the power consumption increases even under statistics, electricity CCFL backlight LCD TV accounted for 90% of overall electricity consumption high . So, change the backlight technology is one of a change in the direction of the current LCD picture quality .

TV purchase these your attention yet
LED is better than LCD picture quality
This rumor logic is clear: Since the LED TV is the latest out, then the quality is certainly better than in the past with CCFL backlight ( commonly known as LCD) LCD TV is good. What this really true ?
As mentioned earlier , LED TV's biggest advantage is long life , high brightness, low power consumption, small size. As to the quality better than that of LCD, but also depends on the spectral characteristics of the LED , high- performance focusing on only those LED TVs , by using particles of a high-performance LED , combined panel and picture quality processing techniques to achieve high quality. In addition , in the past , when the LED TV does not appear , there are many high-end LCD TV by using a high performance CCFL backlight and panel to achieve a high quality , which is the same reason.
5 = buy buy LCD TV panels
LCD panel LCD TV sets accounted for more than 70 % of the cost , this is not to deny the fact . But does that mean that buying a TV panel is to buy it ? The answer is of course no.
The following reasons:
1 , the LCD panel only occupy a larger share of the costs of the machine . For "good" TV and " bad" TV is the same.
2 , bucket theory tells us that the key factor in determining good or bad thing is how short the shortest piece of board , rather than how long the longest piece of board . So if only the LCD panel is good,20x4 lcd display the other bad parts , but also can not make a good TV.
3 , even the best LCD panel plant , out of the products have quality differences. Can not say that so and so long as it is produced in a liquid crystal panel is good, so and so is the production of LCD panels bad .
6 , hard screen than the soft screen strong , impact
This statement is more popular in the last year , many consumers once considered hard-screen LCD TV in front of the screen adds an extra layer of protection , so the more solid , impact resistance. At that time a lot of sales in stores selling television sets in order to prove himself with a "hard screen" , will hand to knock , push the TV screen , in order to prove their strong sales of the TV screen , and durable.
In fact, the difference between hard and soft-screen in the direction of the liquid crystal molecules are arranged just different decision . Hard screen and no additional protective layer on the surface, so it does not seem to be more solid than the soft screen , impact resistance.
In fact , the biggest difference between hard and soft-screen or display different characteristics , focusing on hard screen color reproduction of authenticity , but generally not as soft contrast screen ; soft screen contrast generally good , but the color is more obvious tendency . In fact, this is the difference in style ,Character LCD Modules and physical structure , is strong, durable , and no significant relationship .

3D movies really hurt the eyes do
3D TV is a recently popular new things . But now there are a lot of people say that 3D movies hurt the eyes ,character oled then it really true ?
3D content itself is actually no damage to the eyes . Because we humans are in fact seen every day 3D stereoscopic images . There are still a number of medical institutions in the use of 3D content for young people to correct myopia and treatment , we can see , 3D does not contradict itself and the vision health .
As some people get dizzy watching 3D , uncomfortable , this is actually about and display device itself . For example, some 3D TV in 3D mode due to the lower refresh rate, flicker strong sense , it is easy to arouse the viewer's visual fatigue ; also some 3D sources when shooting because there is no good debugging equipment, resulting depth of field problems, this picture also being looked likely to cause visual fatigue and even nausea , TFT LCD Display uncomfortable. All these questions can not blame onto 3D concept.

Some advantages of commercial LCD display
There are a lot of users do not understand, commercial and civilian display screen exactly what is the difference? Today, the difference between a simple presentation on screen between commercial and residential, hoping to help netizens.
1, clarity
Common display devices support only a few TV common resolution specified in the instructions. Because the resolution is only a few civilian television signals, television LCD screen resolution as long as several civilian users based on common use was more effective treatment, a special resolution will result in the video. Commercial display with intuitive features to reflect the image quality, combined with full 1920 x 1080 resolution display for the field of radio and television equipment selection, the LCD screen is the preferred choice of professional display resolution is automatically adjusted according to the display resolution output rate (regardless if they had to support); its high reliability and high-definition display capabilities will ensure that you can record high-definition video edited, the video signal is displayed in the viewer a complete front.
2, stability
Commercial display products usually require 24 hours non-stop operation to meet the needs of a variety of information display, and a display device using the environment than the civilian environment is much worse, the performance of the product which made a higher demand.
And compared to the ordinary display devices, the design, the current commercial display, power, temperature and resistance to electrical interference, capacity and electric shocks margin and the average time between failures are much larger than the former. In the selection of components, various components of the voltage characteristics, current, temperature, humidity and other providers must use significantly higher than TV components; commercial display must also use fully shielded metal case ensure electromagnetic compatibility and interference.
Normal aging display device manufacturing machine in the pipeline is usually energized about 8 hours at room temperature, and the aging machine supplier obvious need in the high temperature and humidity in a closed environment of aging pipeline aging electricity for more than 24 hours to ensure the machine stability. On installation, commissioning, especially components and the aging process requirements, business requirements are significantly higher.
3, Panel
Although commercial and civilian display TFT LCD panels are used, but there is a big difference between them. The biggest difference between them mainly in the size of the liquid crystal molecules, image processing and color, brightness and contrast, viewing angle and so on.
Ordinary LCD display is more important to performance of the entire screen, a small part of the request is not very demanding, more important is the use of a liquid crystal can reduce the cost of macromolecules. Liquid crystal molecules than ordinary LCD panel 256x64 oled display screen to big business, because commercial display when viewing distance is generally not more than one meter, the most important thing is to show the details of the liquid crystal molecules are smaller, Of course, this panel cost is more expensive.
4, the interface
Of course, there are many common display devices also have a RS-232 control port, but its use is basically just used to control lighting, etc., and can not be achieved in industrial control. Because the feeder demand, commercial displays general use industrial port, such as the color RGBBNC with interface and professional video interface DVI-D self-locking mechanism and so on. In addition, suppliers can be significant S232 serial control, password control and open up to more than 200, to adapt to a variety of industrial environments. Easy to use multi-display, not by remote control can control all display devices, and be able to assist, boot time, delay boot, self-test machines and other industrial requirements.
With the continuous development of display technology, in addition to civil, many display manufacturers have launched a commercial display products, these products are mainly used in many public display areas like subways, airports, shopping malls, etc., used to display a variety of real-time Information for people's daily life provides a great convenience. TFT LCD Displays has become a modern society, people work and live essential equipment.
