Embodiment 1

[0052] Such as Figure 3-5 As shown, this embodiment provides a method for aligning boxes of liquid crystal display motherboards, and the specific steps are shown in image 3 shown.

[0053] The following is an example of coating the sealant and injecting liquid crystal on the array substrate. Of course, the above-mentioned sealant and / or liquid crystal can also be fabricated on the color filter substrate, specifically including the following steps:

[0054] S1. Wire cutting step

[0055] Such as Figure 4 As shown, the array substrate is prepared through an array process and correspondingly forms a plurality of first display regions 4 of a first size (standard screen size) distributed in an array. The array substrate is provided with a first driving circuit 5 and a second driving circuit 51 on two adjacent peripheries of the first display area 4 for controlling the display of the first display area 4 .

Embodiment 2

[0083] This embodiment provides a liquid crystal display substrate with a non-standard size, which is obtained by cutting the liquid crystal display motherboard obtained by the above-mentioned method of aligning liquid crystal display motherboards along the periphery of the sealant 8 .

[0084] The liquid crystal display substrate with a non-standard size prepared in this embodiment has the advantages of uniform cell thickness, no afterimage on the edge of the sealing glue, high vibration resistance of the edge of the sealing glue, and low production cost.

Abstract

The invention provides a method for aligning liquid crystal display motherboards and a liquid crystal display substrate of a non-standard size, belonging to the field of display technology, which can solve the sealing problem of the liquid crystal display substrate of a non-standard size produced by the existing mid-post cutting method The anti-vibration strength is weak, the contact between the sealing glue and the liquid crystal at the cutting place causes afterimages, and the cell thickness of the liquid crystal cell is uneven. In the method for aligning liquid crystal display motherboards of the present invention, for liquid crystal display substrates with non-standard sizes, frame sealing glue is coated around the non-standard screens before cutting. After the box is assembled, cut along the edge of the above-mentioned sealing glue to obtain a non-standard screen, which avoids the weak anti-vibration strength of the sealing part caused by the post-cutting method, the afterimage caused by the contact between the sealing glue and the liquid crystal at the cutting place, and the thickness of the liquid crystal box. At the same time, it can maximize the use of existing mask plates, save materials, and reduce the production cost of non-standard screens.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method for aligning liquid crystal display motherboards and liquid crystal display substrates with non-standard sizes. Background technique [0002] In the ever-changing modern society, liquid crystal display, as a display display graphics terminal, plays an increasingly important role. With the development of modern industry, the manufacture of liquid crystal display substrates is also developing towards integration and automation. There are more and more, and the investment in production lines is also increasing. A 4.5-generation line requires an investment of 1 billion yuan, while an 8-generation line requires an investment of 30 billion yuan, due to the increase in investment scale and daily maintenance costs of the production line. In industrialized production, generally only standard products with large volumes and economies of scale can be produced, such a...
