Problems solved by technology

[0002] At present, when some high-end LCD screens are produced, especially for vehicle-mounted products, customers have high requirements for shading. The current conventional method is to print ink around the edges of the LCD screen to cover them. This method has low efficiency in production and high rework rate. And it is difficult to rework, which has seriously affected the production cycle and quality. At the same time, the labor intensity of employees is high and the loss of materials increases

Embodiment Construction

[0015] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0016] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0017] Such as figure 1 As shown in the schematic diagram of the shading tape, according to the original ink screen printing pattern of the LCD screen, the pattern film is made. The shading part of the film is single-sided with glue. The screen is placed on the operating table, and the pattern film is attached to the LCD screen according to the position.

Abstract

The invention discloses a light-shielding method for a liquid crystal display screen. The light-shielding method includes the following steps that S1, first, light-shielding adhesive tape meeting requirements is purchased; S2, a mold is used for punching the light-shielding adhesive tape into needed patterns; S3, a centrifugal film is covered with the light-shielding adhesive tape subjected to punching; S4, finally, the liquid crystal display screen needing light shielding is placed on an operation table, and according to positions, the pattern attachment film is attached to the liquid crystal display screen. Compared with the prior art, the film attachment mode is adopted for performing light-shielding treatment on the liquid crystal display screen, in this way, the reworking rate is greatly decreased, and the reworking probability is almost zero; meanwhile, the labor intensity of workers is reduced, production efficiency is substantially improved, and the yield is substantially increased. In addition, equipment, ink and a silk screen are not needed, so the production cost is further lowered.

Description

technical field [0001] The invention relates to a light-shielding method for a liquid crystal display screen. Background technique [0002] At present, when some high-end LCD screens are produced, especially for vehicle-mounted products, customers have high requirements for shading. The current conventional method is to print ink around the edges of the LCD screen to cover them. This method has low efficiency in production and high rework rate. And it is difficult to rework, which seriously affects the production cycle and quality. At the same time, the labor intensity of employees is high and the loss of materials increases. Contents of the invention [0003] The object of the present invention is to provide a method for shading a liquid crystal display that can effectively improve production efficiency and reduce rework rate and production cost in view of the above-mentioned technical problems existing in the prior art. [0004] The present invention is achieved through...
