Problems solved by technology

In addition, the difference in pre-tilt angle will also cause inconsistency in characteristics such as liquid crystal response speed, contrast value, and transmittance. This phenomenon will cause differences in the optical properties of each point in the plane, which has a great impact on the stability of the product.
[0006] In order to solve the shortcomings caused by the above-mentioned carrier design, here we propose a series of solutions to solve the phenomenon of different brightness and darkness formed between the supported area and the unsupported area of ​​the carrier

Embodiment Construction

[0056] The present invention relates to a method for making a liquid crystal display panel with both support and voltage application and a supporting carrier used in conjunction with it. In a preferred embodiment, the present invention is mainly applied to the Polymer Stabilized Alignment (PSA) process, combined with ultraviolet (UV) cross-linking exposure, so that the liquid crystal molecules in the liquid crystal display panel generate a specific pre-tilt angle, and then achieve control The process of aligning liquid crystal molecules. In addition, in a preferred process, in order to judge whether the alignment of liquid crystal molecules is good, automatic optical inspection (AOI) can be used to detect before / after exposure and cross-linking. The specific embodiments and steps of the present invention will be further described below with reference to the accompanying drawings.

Abstract

A support carrier for supporting a liquid crystal display panel. The liquid crystal display panel includes a visible area and a non-visible area. The support carrier includes supports. The supporting member is against the bottom surface of the liquid crystal display panel and corresponds to the position of the non-visible area. There is also a hollow space and a plane object in the support. The plane object is arranged in the hollow space and abuts against the bottom surface of the liquid crystal display panel. The hollow space corresponds to the visible area. When a voltage is applied to the visible area, the visible area The plurality of liquid crystal molecules and the plurality of monomers are arranged neatly, so that the plurality of liquid crystal molecules generate consistent pretilt angles. In this way, the liquid crystal molecules in the liquid crystal display panel are subject to the same stress, and no ripples with different brightness and darkness will be produced.

Description

technical field [0001] The present invention relates to a manufacturing method of a liquid crystal display panel and a support carrier used in conjunction therewith; specifically, the present invention relates to a manufacturing method of a liquid crystal display panel applied to a polymer stabilized alignment (Polymer Stabilized Alignment; PSA) process and the supporting carrier used in conjunction with it. Background technique [0002] In the traditional Polymer Stabilized Alignment (PSA) technology for manufacturing liquid crystal display panels, the most critical step is to apply a voltage to the liquid crystal cell (LC cell), so that the monomer (monomer) mixed in the liquid crystal will follow The liquid crystals are aligned under the application of voltage, and the monomers are cured by ultraviolet light cross-linking to produce a specific pre-tilt angle. In this way, the liquid crystal display panel has the ability to control the alignment of liquid crystals (pixels...
