Embodiment Construction

[0020] Please refer to Figure 4 to Figure 5 , is a schematic perspective view of the first embodiment of the backlight module of the present invention and its top view. The backlight module 40 includes a light guide plate 49 and a light source 43 .

[0021] The light guide plate 49 includes a display area 42 and a redundant area 41 adjacent to the display area 42. The display area 42 and the redundant area 41 are integrally injection-molded, both of which are parallelepiped structures, and are made of transparent polymer resin or glass. The display area 42 corresponds to the main display area of ​​the display panel (not shown). The redundant area 41 is located at one end of the light guide plate 49 adjacent to the light source 43, and includes a light incident surface 48 and a light exit surface 47 adjacent to the light incident surface 48, and an auxiliary display area is provided on the light exit surface 47 411. The auxiliary display area 411 corresponds to the auxiliar...

Abstract

The present invention provides a kind of light guide plate and back light module with the said light guide plate. The light guide plate includes one display area and one adjacent redundant area, the display area corresponds to the main display area of the display panel, and the redundant area is used for isolating the dark band caused by uneven incident light and includes one light incoming surface. The light guide plate and the back light module with the said light guide plate have the advantage of simple design.

Description

【Technical field】 [0001] The present invention relates to a light guide plate and a backlight module using the light guide plate, in particular to an edge-light backlight module using a light emitting diode (Light Emitting Diode, LED) as a light source. 【Background technique】 [0002] Since the liquid crystal in the LCD panel itself does not have light-emitting characteristics, in order to achieve the display effect, it is necessary to provide the LCD panel with a light source device, such as a backlight module, whose function is to provide the LCD panel with a surface with sufficient luminance and uniform distribution. light source. [0003] see figure 1 , The backlight module of the prior art is mainly composed of a light source 5, a light source cover 6, a light guide plate 3, a reflector plate 4, a diffuser plate 2 and two light-collecting sheets 1. Wherein, the light source 5 is a line light source, which mainly includes two kinds of electroluminescent lamp (Electrolu...
