Abstract

The invention relates to a manufacturing method of colour light filter, comprising the steps of forming a transparent conductive pattern layer comprising multiple blocks on one surface of a base plate, forming a black matrix pattern on the base plate, and then performing a transfer printing process such that a colour toner with a negative charge is absorbed in partial blocks with positive charges, and finally performing a colour toner curing process so as to form a colour light filter. The invention effectively improves the problems of high production cost and high pollution caused by manufacturing colour light filter through multiple light shields and multiple colour photo resistances.

Description

Technical field [0001] The invention relates to a method for manufacturing a color filter, in particular to a method for fixing solid color particles on a patterned transparent conductive layer by electrostatic force, and then curing the color particles to form a color filter. method. Background technique [0002] With the increasing development of manufacturing technology, liquid crystal display (LCD) has been a widely used display component. It has the advantages of high image quality, small size, light weight, low voltage drive, and low power consumption. In small and medium-sized portable TVs, mobile phones, camcorders, notebook computers, desktop monitors, projection TVs and other consumer electronics or computer products, its working principle mainly uses electric fields to change the arrangement of liquid crystals , The phenomenon of changing the route of light passing through the liquid crystal, and then into a display effect of light and dark changes. Among them, the col...
