Backlight module and liquid crystal display

Abstract

The invention provides a backlight module and a liquid crystal display. The backlight module comprises a light guide plate and a rubber frame. The light guide plate comprises a light-incoming surface, a light-outgoing surface and a bottom surface, wherein the light-outgoing surface and the bottom surface are adjacent to the light-incoming surface. The rubber frame is used for holding the light guide plate and comprises a first side wall adjacent to the light-incoming surface, a first stretching part stretched to the light-outgoing surface from the first side wall and a first boss stretched towards the light-outgoing surface from the first stretching part, wherein the first boss is embedded in an open groove and pressed and clamped on the light-outgoing surface. Through the device, the backlight module disclosed by the invention can tightly combine the rubber frame and the light guide plate so as to prevent gaps between the rubber frame and the light guide plate so that light leak is effectively avoided.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module and a liquid crystal display. Background technique [0002] Due to the advantages of thinness, low power consumption, and no radiation, liquid crystal displays are widely used in electronic equipment such as notebook computers, mobile phones, digital cameras, display terminals, and instruments. Since the liquid crystal itself does not emit light, a backlight module is required to provide a surface light source for it. The light guide plate is an important component in the backlight module, which is used to guide the transmission direction of the light beam emitted by the light source, and convert the line light source or point light source into a surface light source to emit. [0003] figure 1 It is a structural schematic diagram of a backlight module in the prior art. Such as figure 1 As shown, in the existing backlight module, the cooperation method between the plast...

AI Technical Summary

Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to provide a backlight module and a liquid crystal display to solve the problem of light leakage in the prior art due to the gap between the positioning boss and the light-emitting surface of the light guide plate due to the deformation of the plastic frame.
