Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] In order to avoid the colloid being easily deformed due to high temperature during actual use, and thus prone to product quality problems, under the funding of the "National Special Funding for International Science and Technology Cooperation" fund project (Project No.: 2013DFR80830), a series of technical researches were carried out and summarized A solution to significantly improve the failure of high-temperature Mura (the phenomenon of uneven brightness of the display, causing various traces) is proposed. This scheme will be specifically described below.

[0037] In the present invention, in the absence of a contrary description, the orientation words...

Abstract

The invention relates to a reinforcing structure and a preparation of the reinforcing structure, and a liquid crystal screen assembly and a preparation method of the liquid crystal screen assembly. The reinforcing structure comprises a reinforcing glass (1), a polarizer (4), a CF (color filter) glass substrate (3) and a TFT (thin film transistor) glass substrate (2) which are sequentially overlapped, wherein the CF glass substrate and the TFT glass substrate form a first-stage step, the length of the CF glass substrate is smaller than the length of the TFT glass substrate, foam (5) covers the first-stage step, the polarizer and the CF glass substrate form a second-stage step, the length of the polarizer is smaller than the length of the CF glass substrate, a light shielding adhesive tape (6) covers the second-stage step and the foam, and the reinforcing glass is adhered to the surface formed by the light shielding adhesive tape and the polarizer through an optical adhesive (7). The reinforcing structure has the advantages that firstly the foam is filled in a gap, the foam is drawn out in the subsequent period, and the optical adhesive is subjected to ageing treatment; as the usage amount of the optical adhesive is reduced, the deformation after heating is smaller, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of optoelectronic equipment manufacturing, in particular to a liquid crystal display component and a preparation method. Background technique [0002] Reinforced LCD screens are widely used both indoors and outdoors due to their high reliability. Airborne reinforced LCD screens are widely used in aerospace and other fields. Due to their working environment, their working performance requirements are more stringent than ordinary civilian LCD screens. Therefore, they need to pass vibration tests, humidity tests, mold tests and salt spray tests. And high and low temperature work test for performance verification. [0003] Reinforced liquid crystal display, in order to increase the reliability of the liquid crystal display, use optical glue as an adhesive to bond a piece of reinforced glass on top of the general liquid crystal display. In order to improve the reliability of the LCD screen, the size of the reinforced gla...
