Problems solved by technology

Since the temperature can be as high as 190-200°C during the hot pressing process, after the hot pressing is completed, the optical adhesive layer needs to be removed to firmly bond the functional glass to the CF glass, which not only increases the cost, but also reduces the repair time. efficiency
In addition, when the functional glass is removed from the reinforced LCD module, it is completed by physical partition, which is not only time-consuming and laborious, but also often leads to damage to other components of the reinforced LCD module, thereby further reducing repair costs. Pass rate

Abstract

The invention discloses a reinforced liquid crystal display module and a repair method thereof. The reinforced liquid crystal display module comprises functional glass (2), optical adhesive layer (6), CF glass (5) and sequentially connected from top to bottom. TFT glass (1), characterized in that the bottom surface area of ​​the functional glass (2) is not greater than the top surface area of ​​the CF glass (5), and the bottom surface area of ​​the CF glass (5) is smaller than the TFT glass (1) ), the edge of the top surface of the TFT glass (1) is connected with FPC (3), and the FPC (3) is connected with the CF glass (5), optical adhesive layer (6) and functional glass (2) There are gaps formed therebetween. The FPC of the reinforced liquid crystal display module can be quickly repaired after being damaged and has an excellent repair pass rate.

Description

technical field [0001] The invention relates to a liquid crystal display unit, in particular to a reinforced liquid crystal display module and a repair method thereof. Background technique [0002] Ruggedized liquid crystal display modules are generally used in products with relatively harsh environments, and need to have the characteristics of impact resistance, high and low temperature resistance, electromagnetic compatibility resistance and salt spray mold resistance. Currently, the reinforced display module is made by reinforcing functional glass on an ordinary liquid crystal display. Then this processing method will often cause circuit failure of the liquid crystal display, especially the key device FPC (flexible circuit board). As a signal connection and transfer device, FPC itself is made of soft film-like materials, and its own stability is not high, so it is the most easily damaged device during the reinforcement process. The existing reinforced liquid crystal dis...
