AI Technical Summary

Problems solved by technology

Dye is used in traditional color filters, which can meet the requirements of high light transmittance and color saturation, but the optical rotation resistance and heat resistance of the dye are poor
In order to overcome this problem, the pigment dispersion photoresist material has replaced the dye method and become the mainstream; with the development of large-size TV panels, which require high brightness and increase the temperature of the panel, in order to pursue high color saturation, photoresist pigment particles must be reduced to Prevents scattering, which makes the heat resistance of the previous color filter grade pigments insufficient to meet the requirements of the LCD manufacturing process for TVs

Abstract

The invention discloses a heat resistant flexible color filter, which comprises a flexible transparent substrate and a thermally stable color photo-resistance material coated on the flexible transparent substrate, wherein the forming material of the substrate comprises silicon dioxide and polyimide, and the silicon dioxide accounts for 20 to 70 weight percent of the forming material; and the thermally stable color photo-resistance material comprises 30 to 90 weight percent of alkali-soluble resin system, 5 to 60 weight percent of photosensitive system and 10 to 50 weight percent of inorganic alkoxide coated pigment.

Description

technical field [0001] The invention relates to a color filter, and in particular to a heat-resistant flexible color filter formed by a silicon dioxide and polyimide mixed substrate and a heat-stable color photoresist material. Background technique [0002] The manufacture of color filters for thin-film transistor liquid crystal displays includes black photosensitive resins that form black frames to prevent light mixing and red, green, and blue color photoresists for light filtering. Among them, the color photoresists must have good light transmittance and saturation. Spend. Traditional color filters use dyes to meet the requirements of high light transmittance and color saturation, but the dyes have poor optical resistance and heat resistance. In order to overcome this problem, the pigment dispersion photoresist material has replaced the dye method and become the mainstream; with the development of large-size TV panels, which require high brightness and increase the temper...
