Problems solved by technology

[0004] The diffusion plate will cause a large amount of light energy loss in the process of diffusing the light of the light source. At the same time, after the diffusion plate is used, the purchase cost of parts and the installation process of the TV set are increased, and the production cost of the TV set is increased. reduce production efficiency
[0005] In the process of realizing the present invention, the inventors found at least the following problems in the prior

Example Embodiment

[0024] Example one:

[0025] Such as figure 1 As shown, the present invention provides a backlight module 100, which includes a liquid crystal panel 3 installed in sequence, an optical film fixedly arranged on the lower polarizing surface of the liquid crystal panel 3, supporting the liquid crystal panel 3, and The back plate 1 of the optical film 2 and the reflective sheet attached to the inner wall of the back plate 1, the open end of the back plate 1 is provided with a step groove 13, and the liquid crystal panel provided with the optical film Installed in the step groove 13.

[0026] The invention adopts a new type of backlight module, omits the diffuser in the existing backlight module, and directly installs the optical film on the LCD panel. The LCD panel and the optical film are integrated by the open end of the back plate. Support. After the diffuser is removed, the light energy loss caused by the diffusion of the light source by the diffuser is reduced, and at the same t...

Abstract

The invention provides a backlight module, which comprises a liquid crystal display panel, an optical diaphragm, a back plate and a reflector plate, wherein the liquid crystal display panel, the optical diaphragm, the back plate and the reflector plate are arranged in sequence; the optical diaphragm is fixedly arranged on a lower polarization plane of the liquid crystal display panel; the back plate is used for supporting the liquid crystal display panel and the optical diaphragm; the reflector plate is attached to the inner wall of the back plate; the open end of the back plate is provided with a stepped slot; and the liquid crystal display panel provided with the optical diaphragm is arranged in the stepped slot. The invention also provides a television. The technical scheme provided by the invention is that a diffuser plate in a traditional backlight module is removed, and therefore, the optical energy loss caused by the diffusion of the diffusion plate to a light source is reduced, the number of light-emitting diode (LED) lamps can be reduced, and the energy consumption of the backlight module is reduced. As the diffusion plate is removed from the backlight module, the purchase cost of the diffusion plate is also saved, the assembly process of the backlight module is simplified, the production efficiency is improved, and further, the overall cost of the television is reduced.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a backlight module and a television set including the backlight module. Background technique [0002] In the direct-type backlight module, a diffuser plate is required to play two main functions of diffusing light and supporting the optical film. [0003] At present, in direct-lit backlight modules, whether it is a CCFL (Cold Cathode Fluorescent Lamp) light source, an LED (Light Emitting Diode) light source, or other light sources, the diffusion plate is indispensable in the optical structure of the backlight module. made of. [0004] The diffusion plate will cause a large amount of light energy loss in the process of diffusing the light of the light source. At the same time, after the diffusion plate is used, the purchase cost of parts and the installation process of the TV set are increased, and the production cost of the TV set is increased. Reduce production efficiency. ...
