Problems solved by technology

As a result, the weight of the side-type backlight module is relatively large, especially for a larger size of the backlight source, which increases the overall weight of the backlight module
At the same time, the cost of such a backlight module with a light guide plate is relatively high

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] figure 1 A backlight module 10 according to the present invention is shown. like figure 1 As shown, the backlight module 10 includes a bottom reflector 4 , a frame 2 , a light source 3 , a side reflector 5 and a transflective film 1 . Wherein, the bottom reflection sheet 4 is arranged horizontally. The frame 2 is arranged on the edge of the bottom reflection sheet 4 . The side reflection sheet 5 is arranged on the frame 2 and forms a hollow reflection cavity 6 with the bottom reflection sheet 4 . The light source 3 is fixedly arranged on the wall of the reflective cavity 6 . The transflective film 1 is arranged at the opening of the reflective cavity 6 and overlapped with the light source 3 and the side reflector 5 .

[0031] In the backlight module 10 of the present invention, no light guide plate is required, thereby avoiding the problems of heavy weight and ...

Abstract

A backlight module (10) and a liquid crystal display device (100) containing same. The backlight module (10) comprises a horizontally arranged bottom reflective sheet (4), a frame (2) arranged at an edge of the bottom reflective sheet (4), a side reflective sheet (5) fixedly arranged on the frame (2) and forming a hollow reflective cavity (6) with the bottom reflective sheet (4), a light source (3) fixedly arranged inside the reflective cavity (6), and a transflective film (1) arranged at an opening of the reflective cavity (6), wherein the transflective film (1) is connected to the light source (3) and the side reflective sheet (5) in an overlapped manner. Thus, the backlight module (10) has a light overall weight and low production costs.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module and a liquid crystal display device comprising the same. Background technique [0002] In a traditional liquid crystal display device, since the liquid crystal panel itself does not emit light, an external light source is required for display. Generally, such backlight modules include backlight and reflective light sources. Since the backlight light source does not need to be affected by the environment, almost all the light sources in current liquid crystal display devices are backlight light sources. [0003] And the current backlight modules can basically be divided into two types: side-type and direct-type. The side-entry type has the advantages of low power consumption and thin thickness. However, due to the side entry type, a light guide plate is required. As a result, the weight of the side-type backlight module is relatively large, especially fo...
