Backlight module and television

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. ...

AI Technical Summary

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 art: the use of a diffuser plate in the backlight module structure not only increases the cost of components, but also increases the assembly process and production difficulty of the TV set, reducing production efficiency; The use of the diffusion plate also leads to a large amount of light energy loss, which requires an increase in the use of optical films, which indirectly increases the production cost of the product and increases the energy consumption of the TV set
