Embodiment Construction

[0015] See image 3 , using an embodiment to illustrate the edge-lit backlight module 2 of the present invention. The edge-lit backlight module 2 of this embodiment is composed of a frame 21 , a light-diffusing device group 22 , a light guide plate 23 , a reflective backplane 25 and light source groups 26 arranged on both sides. The edge type backlight module 2 of this embodiment and figure 1 The difference of the shown existing edge-lit backlight module 1 is that the existing edge-lit backlight module 1 separates the reflective sheet 14 from the back plate 15, while the edge-lit backlight module 2 of this embodiment separates the reflective sheet and the backplane 15. The functions of the backboard are combined into one, and exist in the form of a reflective backplane 25 . As for other components, they are the same as the existing edge-lit backlight modules, for example, the light source group 26 is provided with a lamp tube 161 as a light source, a light source group refle...

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...
