Problems solved by technology

[0004] When curing the sealant, use ultraviolet rays to perform ultraviolet rays on the display panel after the box is completed ( figure 1 As shown by the middle arrow), due to the design accuracy of the mask plate 6 used for curing the frame sealant and the divergence of ultraviolet rays, a certain amount of ultraviolet radiation will also be generated in the display area of ​​the display panel, as figure 1 The distance between the middle mask plate 6 and the sealant is d, and the ultraviolet light is irradiated from the above-mentioned area with a width of d to the periphery of the display area of ​​the display panel, so that the metal layer at the edge of the display area of ​​the array substrate 1 is inevitably damaged. For example, when the pixel electrode layer is irradiated with ultraviolet rays, the electrons received by the metal layer migrate, and when they migrate to the alignment layer 4 that is in contact with the edge of the display area, it will affect the deflection of the liquid crystal molecules in the display area. The edge of the area produces defects such as uneven brightness, which seriously affects the picture quality

Embodiment 1

[0028] like figure 2 and 3 As shown, this embodiment provides a method for preparing a display substrate, including the step of irradiating the display substrate with ultraviolet light for the first time after the orientation layer 4 of the display substrate is oriented, so that the electrons in the metal layer of the display substrate migrate to the alignment layer 4.

[0029] In the preparation method of the display substrate in this embodiment, after the alignment layer 4 of the display substrate is oriented, the display substrate is irradiated with ultraviolet rays, so that the electrons on the metal layer of the display substrate receive energy and migrate under the first ultraviolet irradiation, uniform Distributed on the alignment layer 4 of the display area of ​​the display substrate, although charges are distributed on the alignment layer 4 like this, the above-mentioned charges are evenly distributed throughout the display area, and the influence on the liquid crys...

Embodiment 2

[0038] like figure 1 As shown, the embodiment provides a method for preparing a display panel, including the method for preparing a display substrate as described above, and also includes:

[0039] S1: Prepare an opposite substrate, and the opposite substrate is used to form a display panel with the display substrate;

[0040] That is, when the finished display substrate is an array substrate, at this time, the opposite substrate to be prepared is a color filter substrate, and vice versa.

[0041] Both the array substrate and the color filter substrate prepared above include an alignment layer 4 on the side facing the liquid crystal, and the alignment layer 4 is rubbed and aligned.

[0042] The preparation methods of the above-mentioned array substrate and color filter substrate, and the coating and rubbing of the alignment layer 4 are all within the scope of the prior art, and will not be repeated here.

[0043] S2: coating a frame sealant on the display substrate or the op...

Embodiment 3

[0055] This embodiment provides a display device, which includes the display panel prepared by the above-mentioned method for preparing a display panel.

Abstract

The invention provides a manufacturing method of a display substrate, a manufacturing method of a display panel and a display device. The problems that in the prior art, when irradiation light of ultraviolet light migrates to an orientation layer in contact with the edge of a display area, deflection of liquid crystal molecules of the display area is influenced by electronics in a metal layer of a display substrate, and therefore the defects of uneven brightness and the like are generated to the edge of the display area, and image quality is seriously influenced are solved. According to the manufacturing method of the display substrate, the manufacturing method of the display panel and the display device, after an orientation layer of the display substrate completes orientation, ultraviolet irradiation is carried out on the display substrate, electronics on a metal layer of the display substrate can receive energy under ultraviolet irradiation of the first time to migrate and be evenly distributed on the orientation layer of a display area of the display substrate, charges are evenly distributed on the whole display area, and the defect that the brightness of the edge of the display area is uneven is overcome.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for preparing a display substrate, a method for preparing a display panel, and a display device. Background technique [0002] In recent years, with the popularization of digital TV, the traditional CRT display has been replaced by a new generation of display technology due to its difficulty in digitization, large size, heavy weight, and radiation. , thin size, no radiation, low power consumption, good display effect and other advantages have begun to be widely popularized and become mainstream products. The manufacturing process of the liquid crystal panel includes the following steps: an array substrate preparation step, a cell alignment step, and a module preparation step. Among them, the box alignment process includes: the step of printing liquid crystal alignment film, the step of rubbing alignment of liquid crystal alignment film, the step of coating fram...
