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

A side-light backlight module and a liquid crystal display device. The side-light backlight module has a light source group, a light guide plate and a reflective backplane. The reflective backplane has a first surface that can reflect light and a bent portion bent toward the first surface, and the light guide plate is arranged on the first surface of the reflective backplane and connected to the bent portion, and the light guide plate A cavity is formed between one side of the side and the bending part, and the light source group is installed in the cavity. Wherein, the first surface of the reflective backplane can be molded or coated with a reflective layer to make it have light reflective properties.

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...
