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.

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.

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 .

Organic thin film deposition process

OLED device in a high vacuum deposition chamber plurality of organic material film, the film quality is related to the quality and life of the device key. In the vacuum chamber has a plurality of heating boat evaporation sources and the corresponding thickness monitoring system, graphic lcd 128x64 ITO glass substrate fixing means, and the metal mask means (Mask). A relatively high vapor pressure organic materials, the evaporation temperature at 100-500 ℃ between, on their characteristics:
1, high vapor pressure (150-450 ℃).
2, easy to decompose under high temperature conditions, volatility.
3, good thermal conductivity foam state.
Depositing an organic material film in the evaporator, the evaporation rate is controlled lose 3-5Å / s, so that the substrate of Φ60 mm film uniformity range of up to 350Å ± 25Å. Heating the boat with good thermal conductivity, easy to control the evaporation rate. Common heating molybdenum boat and tantalum metal heating boat, in order to make more uniform heating, plus quartz boat cover, that the heating be buffered. During the vapor deposition of organic material film, generally the substrate kept at room temperature, to prevent damage to the organic material film temperature, evaporation rate should not too fast or too slow, uneven thickness of the film is too thick. Evaporation of a variety of materials were carried out in several vacuum chamber, to prevent cross-contamination. The production of the color OLED device, comprising an organic dopant material film formation,Lcd display modules to take dopant material with the matrix material of the evaporation process, the general control of dopant materials 0.5-2% (of the number of moles of the matrix material ), required in the control matrix material and evaporation to the strict control of the dopant concentration in the matrix material.

Three touch technology

Resistive touch technologies: resistive touch technology is the most commonly used touch-screen technology. For the high flow of business applications, and on the screen drops and other residues immunity. The resistive touch screen is usually the lowest-cost solution. React to pressure, with a finger, gloved hand, stylus or touch like credit cards such other objects.custom lcd
Surface capacitive touch technology: surface capacitive touch technology display much clearer definition than the commonly used plastic film resistive touch. Detecting changes in capacitance caused due to the touch, the sensor is located in the four corners of the display surface capacitive type display. Kind of touch screen with your fingers or other capacitive objects touch incentive.
Protective capacitive touch: protective capacitive touch is a technology that only recently entered the market. The technology can also provide excellent light transmittance, but also the advantage of having a specific surface capacitive touch better. Projection-type capacitive touch does not require positional alignment, and can provide a much higher positional accuracy. Projection-type capacitive touch another exciting place to be, that is, it is also able to support multi-touch.TFT LCD Misplays
