P‐12.7: Accurate and detailed adjustment of liquid crystal azimuth to improve the taste and transmittance of UV2A process

Abstract

By comparing the liquid crystal azimuths of Mura area and OK area, it is concluded that there are differences between azimuths of Mura area and OK area when they are compared with the azimuths of theoretical, but the differences between azimuths of Mura area and azimuths of theoretical are larger. It is proved that the differences can be reduced by directional adjustment of TFT/CF exposure energy and optimization of specific substrate PI film thickness, Improve the taste level of products, and at the same time, improve the panel transmittance.
