Problems solved by technology

[0003] The existing backlight module is equipped with a middle frame to support the liquid crystal display panel and block light leakage. Usually, the middle frame is made of plastic injection molding. During the impact process of the reliability test, the liquid crystal display panel in contact with the plastic middle frame is prone to cracking; moreover, the injection molding mold for the plastic middle frame has a long production cycle and high price, resulting in high development costs for a long time no less

Abstract

The invention provides a liquid crystal display module, which comprises a backlight module, a liquid crystal display panel and a front frame, wherein the front frame is arranged on the liquid crystal display panel which is disposed on the backlight module. The backlight module comprises a middle frame made of elastic materials, and the liquid crystal display panel is arranged on the middle frame. The middle frame made of elastic materials has better buffer capacity to enable the liquid crystal display panel to be tightly matched with the middle frame, and accordingly when the liquid crystal display panel is heated to expand, the middle frame is elastically deformed without extruding the liquid crystal display panel, and when an external environment returns to normal, the liquid crystal display panel returns to normal size, and the middle frame is recovered from elastic deformation and still in tight fit with the liquid crystal display panel. Damage, breakage and the like of the liquid crystal display panel caused by resile failure of a plastic middle frame in the prior art are avoided, and the middle frame is short in manufacturing cycle and low in cost as compared with the injection molded plastic middle frame.

Description

technical field [0001] The invention relates to a liquid crystal display module, in particular to a liquid crystal display module with a middle frame made of rubber material. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glasses. There are many small vertical and horizontal wires between the two glasses. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light from the backlight module is refracted. Generate screen. Since the liquid crystal display panel itself does not emit light, it needs the backlight provide...
