Liquid crystal display panel with Gamma correction function and manufacturing method thereof

Abstract

The invention is a LCD panel with gama correcting function and its making method, firstly coating optical epitaxial material on the bottom basal plate and exposing the optical epitaxial material, to make the positions corresponding to the red, green and blue pixels have different exposing quantities, respectively, so as to generate different optical epitaxial effects. It mounts the bottom basal plate on to a top basal plate, and fills a liquid crystal layer in between them. Because of the difference in epitaxial effect, in the liquid crystal layer, the liquid crystal molecules corresponding to the red, green and blue pixels have different optical penetration rate and can be used to adjust gama curve of the red, green and blue three colors lighting.

Description

technical field [0001] The present invention relates to a liquid crystal display panel with a gamma correction function and a manufacturing method thereof, in particular to a liquid crystal display panel and a manufacturing method thereof that correct the separation of red, green and blue gamma curves to improve display color accuracy. Background technique [0002] With the rapid progress of thin-film transistor manufacturing technology, liquid crystal displays are widely used in personal digital assistants, notebook computers, digital cameras, video recorders, mobile phones, etc. in electronic products. In addition, since the liquid crystal display is a non-self-illuminating display, a cold cathode lamp is traditionally used as a backlight source, and at the same time, a display signal is input through a liquid crystal driving circuit to control the light transmittance of the liquid crystal layer of each pixel of red, green and blue. The purpose of full-color display is ac...

Problems solved by technology

[0008] 1. Before making the pixel electrodes, it is necessary to add a process to make the transparent organic layer 312, resulting in increased manufacturing cost and time

[0009] 2. Since the transparent organic layer 312 has different thicknesses corresponding to the positions of pixels of different colors, the upper surface of the transparent organic layer 312 is uneven, thus increasing the amount of alignment film 320 on the pixel electrode 310 in the subsequent liquid crystal alignment process. Difficulty of the upper surface

[0010] 3. The pixel electrode 310 covers the rugged upper surface of the transparent organic layer 312. Since the adjacent transparent organic layers 312 of different colors have different thicknesses, a transverse electric field is generated between the pixel electrodes 310 corresponding to different display colors, which affects the liquid crystal molecules. alignment, affecting the normal operation of the liquid crystal layer 200
