Large-size color filter manufacturing process and other technical TFT Display Module

COA technology
COA technique is to prepare a color resist technology on the TFT substrate, its main advantage is that it can increase the pixel aperture ratio and the lcd modules  the applied high-end products. In addition, because there is no CF glass substrate and the TFT substrate alignment problem can be reduced so that the difficulty of the process cell. But the technology will lead to a substrate COA overall yield rate. In addition, in order not to affect the normal operation of the TFT, but also requires a dielectric constant less than 3.5 color resist.
Resin BM
BM conventional materials used for the Cr / CrO, but there is a high reflectance, and environmental pollution problems. Therefore, the inorganic metallic materials have been gradually replaced by the organic resin-type BM. As a negative photoresist resin-based process and the BM color pigments resist the same manufacturing process.
OLED with color filters
The use of color filters to achieve white OLED + OLED color display has gradually been many research institutions and enterprises are concerned.
Industry Status and Prospects
Since Japan's Toppan Printing and Dai Nippon Printing, respectively, in 1985 and mass production of color filters since 1986, the majority of patents are Japanese manufacturers to master. But with industrial development, Taiwan, South Korea also by obtaining authorization and independent research and other ways to enter into this industry, but the character oled display panel manufacturers have come to realize that the color filter is the trend homemade. Domestic production line of color filters less, and more for G 4.5 or less. With the domestic high-generation TFT production line and matching color filter production line put into operation, will change the color filters to import large quantities of the situation, raise the level of domestic LCD industry chain.
