Abstract

The invention is a side light-type backlight module and a LCD, where the former has a light source group, a light guide plate and a reflecting backboard. The reflecting backboard has a first light-reflecting surface and a bent part bending to the first surface, the light guide plate is arranged on the first surface and connected to the bent part, one side of the light guide plate and the bent part form a cavity between, and the light source group is installed in the cavity. And the first surface above can have a light-reflecting character with the help of pressure casting or coating a reflecting layer.

Description

technical field

[0001] The invention relates to a backlight module, in particular to a side-light backlight module and a liquid crystal display device which are combined into simplified components by using a back plate combined with a reflective sheet. Background technique

[0002] With the evolution of display technology, display devices have continuously evolved from traditional cathode ray tubes (CRTs) to produce various new display devices. Among them, the liquid crystal display device (LCD) has the advantages of thinness, lightness, power saving, low radiation, etc., so it has gradually become one of the common display devices today, and can be widely used in notebook computers, digital cameras, camcorders, mobile phones and other communications, information or consumer electronics.

[0003] The liquid crystal display device mainly uses a liquid crystal panel (LCD panel) for displaying. Since the liquid crystal panel itself does not emit light, it is necessary to suppl...
