Advanced Development of Polyimide Color Filters for Liquid Crystal Display Applications

摘要

This report lists the approaches taken to improve the properties of color filter materials for Flat Panel Display applications. Significant developments include a high saturation blue dye with high temperature stability; a purification process for a black dye used to replace a combination of blue and brown dyes for a new black matrix material with increased optical density with specific application for the liquid crystal display industry; the development of a rapid thermal curing technique to allow for higher dye loaded materials; and the use of a higher transparency polymer in the blue formulation to improve peak transmission properties.
