The defect of light leakage caused by the misalignment of the upper and lower substrates is completely solved in the COA process.
The use of finer pigments makes the contrast, the gamut, and the white balance better.
Compared with the traditional CF exposure machine, the high-resolution TFT exposure machine made the circuit finer, and the aperture ratio better.
In the G7 generation, high-profile TV panels have been introduced in Taiwanese factories and mass-produced using the Inkjet process to reduce the usage of color resists. The higher generations of G8.5~G11 require customized color resists.
High-profile TV panels have been introduced in China for the G8.5 generation and above, and they are trying to use them in large quantities.
The main COA color photoresist supply is still mainly Japanese, and we are striving for new achievements.
The COA color resist specification used in the G8.5 generation focuses on high resolution, low CD Bias and higher contrast.
The new COA color photoresist is also used in the G8.5 generation white light OLED WCF process. The low-temperature color photoresist used can adjust the color and white balance according to the white light spectrum, which can increase the color performance of higher efficiency.
