Problems solved by technology

The efficiency of surface silk screen printing will be extremely reduced
[0005] 3. Traditional LCD screen printing is almost completely manual work
Today, when the cost of human resources is rising sharply, the traditional external silk screen method consumes a lot of labor and is extremely inefficient.
Moreover, the quality and efficiency of silk screen printing depend entirely on individual skills, which also affects the enthusiasm of various manufacturers to develop brightly colored color LCD screens.
[0006] Since multi-color surface screen printing is used as an auxiliary process of LCD and it is labor-intensive
Many enterprises completely abandon the production of multi-color surface silk screen products; or outsource the surface silk screen printing process to some small silk screen processing factories, but it is not easy to control the quality of the products

Embodiment Construction

[0014] 1. After the box forming process, directly screen-print the multi-color surface on one side of the LCD standard box, then print a layer of protective glue, and then heat-cure at 130°C to form a film. At this time, the number of multi-color surface silk screen printing of a pair of standard boxes is N+1 times.

[0015] 2. When it is necessary to screen print on the double-sided multi-color surface of the LCD standard box, after completing the screen printing on one side, the multi-color screen printing on the other side can be carried out, and then a layer of protective glue is printed, and then heated at 130°C Solid film. At this time, the number of multi-color surface silk screen printing for a pair of standard boxes is 2N+2 times.

Abstract

The invention discloses a screen printing method for a multicolor surface of a liquid crystal display (LCD), which relates to the technical field of LCD production. The method comprises the following step of: after a box formation process, directly performing multicolor surface screen printing on the LCD standard box. The method disclosed by the invention is completely avoided from influence from tolerance in procedures, such as subsequent cutting, sheet creaking and the like, and has high precision as well as high efficiency.

Description

technical field [0001] The invention relates to the technical field of LCD (liquid crystal display) production. Background technique [0002] In the LCD production process, in order to make the LCD have better color or graphic performance, surface silk screen printing (also called external silk screen printing) is often done on the bottom surface before the process of attaching polarizers. Surface silk screen printing is available in monochrome or multi-color as required. The more silk screen colors, the richer the color performance of LCD. The traditional surface screen printing is after the box is formed in the previous process, after the middle process of cutting-liquid crystal filling-dispensing-split-electric visual inspection, then surface screen printing (external screen printing), and then complete the product by pasting polarizers production. At this time, when performing surface silk screen printing, since the standard box has been split into small pieces accord...
