the manufacturing technology of the high degree of automation, industrial mass production characteristics. TFT - LCD industry mature technology, the yield of mass production reached more than 90 [%]. the applicable scope wide, from 20 ℃ to + 50 ℃ temperature range Low Temperature Display can be used normally, after temperature reinforcement of TFT - LCD low working temperature can reach 80 ℃ below zero. Can be used as mobile terminal, according to a desktop terminal display, and can be used as a large screen projection TV, is the excellent performance of full-size video display terminal. the good features of environmental protection: no radiation, no flicker, no damage to the health of consumers. Especially TFT - LCD the emergence of electronic books will bring human beings into a paperless Lcd display module office, no paper printing time, cause human study, dissemination and civilization revolution of the way. TFT - LCD is easy to be integrated and renewal, is a large-scale semiconductor integrated circuit technology and the perfect combination of light source technology, continue to has a great potential for development. There are amorphous, polycrystalline and monocrystalline silicon TFT - LCD TFT of other materials in the future, there are both of glass and plastic substrates.
TFT LCD display screen is the feature of good brightness, high contrast, administrative levels feels strong, bright color, but there are also more power consumption and high cost. To speed up the development of the mobile phone color TFT LCD technology. A new generation of color screen mobile phone a lot of support in 65536, according to the color or even support 160000 color display, TFT high-contrast at this moment, the advantages of rich

Character LCD Modules screen pixel repair tips
Thank Chen Qu delivery
Now monitors, laptops , tablet PCs , mobile phones and digital cameras and other devices use the color lcd display module screen . Sometimes when we stare at the screen , you will find it at more than a few small points, that is, we often say that the dead pixels. Although fewer dead pixels does not affect the image display , but it looks unsightly always compare , then here we use a few tips to get these small dead pixels.
Causes dead pixels
As the LCD panel production defects , appears on the LCD screen, dead pixels is a very common problem , the LCD screen is composed of a lot of points, each point of the pixel from the RGB color changing color and image formation . But when the pixel problems, so that the color does not change , the formation of dead pixels. Dead pixels are usually divided into several, if it is colored bright spot, it shows that the point of the pixel is just stuck , we can repair this kind of dead pixels . However, if it is black dark point , it means that the point completely broken, even if the restoration is invalid . If you are a new user purchased the product and found more dead pixels , it is best to find a vendor to be exchanged immediately . Note, however, that some manufacturers do not pay for the small amount of dead pixels , for example, some of the liquid crystal display , if the dead pixels or less in three words , I would not swap users .
Marker extrusion
Turn on the computer and the monitor , the screen display is set to a plain black screen ( or other contrasting colors and dead pixel solid ) , so you can make highlights at a glance. Got the pen cap is smooth , it would be the highlight of the cap gently squeeze the front , then you can see the white light, if not, you can slightly increase little harder . About 5 to 10 under after extrusion , the internal Graphic LCD Module screen flow , you can let stuck pixel back to normal, and then let the bright spot disappears.
Gently squeeze with a cap will have some effect dead pixels
Hot towel heating
Use cap squeeze LCD screen may be because the user's force is too large for the screen damage , if you doubt the power , then we can also use relatively safe method to repair a hot towel heating highlights . A towel soaked in hot water , if possible , the use of fire for heating the pot filled with water until it appears at the bottom bubbles. To remove the towel , wear insulated gloves wring it . Will be placed in a plastic bag in a hot towel on the screen there are bright spots , try to ensure that heat is concentrated in bright office , heat about 10 minutes, making the internal LCD display heat flow , so that the bright spot disappears.

CLED and OLED those things oled module
CLED and OLED Module Both are self-luminous , brightness, contrast and so little difference , OLED advantage of thinner that can be done , but CLED also has some advantages, such as longer life expectancy than OLED , and lower cost than OLED . As long as yield improvement , cost will be lower than the OLED .
Sony due to technical problems , failed to produce a large-screen OLED, which turned CLED research and development, pilot production of 55 -inch prototype CLED , I mainly want to get rid of the dependence of large flat display panel . But the small screen , is still not given up on the use of OLED R & D , indicating little difference between the two properties ,SPI lcds the same is the future mainstream of development of new display .

Polarizing surface treatment TFT Display Module
Surface processing to increase the optical and mechanical properties of the polarizing film. In order to meet the current requirements of a variety of LCD, with complex function polarizing already on the market. SPI oled
1 anti-reflection (AR) treatment
When the light passes through the surface of a polarizing film, there will be about 5% of the reflection losses, because the loss of luminosity and the reflected light will cause the LCD to identify the degree of reduction. The method of improving the surface of the polarizing film is a metal film deposited on the use of light interference principle to reduce the reflection value of the reflection rate to 1% or less.
(2) anti-glare (AG) treatment
In order to avoid excessive concentration of the light is, the polarizing film processing into uneven surface, the light is uniformly dispersed, can achieve the effect of glare. AG has been processed, the surface up to 3H pencil hardness than scratch, another high fog applicable to large-size products (greater than 12.1 "), mainly due to strong backlight LCD's relationship with another LCD's resolution request for additional level as UXGA (1600 x 1200) AG requirements for more detailed treatment, currently polarizer manufacturers also started to notice this regard, I believe that there will be corresponding product for the most recent market assessment. 3.5 TFT display module
