Liquid crystal module and fixing structure of driver board of liquid crystal module

Abstract

An embodiment of the invention discloses a fixing structure of a driver board of a liquid crystal module. The fixing structure comprises a liquid crystal panel, a back plate, the driver board, a connecting flexible board and a fixing support, wherein the driver board is electrically connected with the liquid crystal panel by the connecting flexible board, the fixing support is mounted on the back plate, and the driver board is mounted on the fixing support and is separated from the back plate by the fixing support. The fixing structure of the driver board of the liquid crystal module is provided with the fixing support, so that the assembled driver board is separated from the back plate by a certain distance, no matter if condensate water drops of mist are generated on the back plate, the condensate water drops are not easy to flow to the driver board owing to the separation action of the fixing support, and problems of short circuit and burning of the driver board are not easy to cause.

Description

technical field [0001] The invention relates to a liquid crystal module in the liquid crystal display field, in particular to a fixing structure of a driving board in the liquid crystal module. Background technique [0002] In the field of LCD TVs, LCD modules are indispensable components in LCD TVs. see figure 1 , the basic structure of the liquid crystal module includes a backplane 11, a backlight module 12, a plastic frame 13, a liquid crystal panel 14, a driver board (also called a source board) 15 and a connection soft board (also called a flexible COF) 16. Among them, the backlight module 12 includes an LED backlight light source and a light guide structure, and the most commonly used one is an edge-lit backlight module at present. The specific structure of the edge-lit backlight module includes heat-dissipating aluminum profiles, LED light strips, light guide plates, several optical films, etc. The liquid crystal panel 14 is arranged above the backlight module 12 a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the driving board 15 is generally fixed on the backboard 11 by screw riveting and positioning. Due to changes in the use environment, water accumulation or fog condensation often causes the bottom surface of the backboard 11 to easily form water accumulation. It will flow to the drive board 15 through the back board 11, especially since the drive board 15 and the back board 11 are riveted and connected by screws, it will cause accumulated water to burn the drive circuit on the drive board 15, resulting in TV burn-in

Therefore, the fixing method of the drive plate 15 by screw riveting and positioning has certain disadvantages. From the perspective of quality, there is a certain rate of burn-in phenomenon, which affects the quality of the company's products.
