Problems solved by technology

[0005] Due to the material selection and design of the back plate, the aluminum plate or steel plate is integrally formed. However, although the aluminum plate is light in weight, it is a high-cost material with weak strength; on the other hand, although the steel plate is cheap and high in strength, it is heavy But it is criticized, it will increase the handling cost, and it is not conducive to the thin and light design

Embodiment Construction

[0043] The present invention discloses a direct-type backlight module and its application. It has a frame-type back frame module to replace the traditional backplane, so that the weight of the backlight module can be reduced, the material of the backplane can be saved, and the cost of the backlight module can be reduced. A thinner and lighter liquid crystal display device is obtained. In order to make the description of the present invention more detailed and complete, refer to the following description and cooperate Figure 4A to Figure 7 icon of the .

[0044] Please also refer to Figure 4A 4B , which respectively show a schematic diagram of a back frame module of a direct type backlight module according to a preferred embodiment of the present invention, and an exploded view of the rear side of the back frame module device. The direct type backlight module of the present invention is mainly composed of a back frame module 200a and a light source disposed on the front of ...

Abstract

The invention discloses a direct type backlight module and its application, which at least comprises a back frame module and a light source, and the light source is arranged at the back frame module. The back frame module comprises multiple brackets which are assembled to a framework. The direct type backlight module can be applied in liquid crystal display devices.

Description

technical field [0001] The present invention relates to a direct type backlight module (Direct Type Backlight Module) and its application, and in particular to a direct type backlight module with a frame type backlight module and a liquid crystal display (LCD) device using the same. Background technique [0002] Among the current flat-panel displays, liquid crystal display is one of the fastest-growing and most sound technologies. Not only is the front-end glass technology of the liquid crystal display panel progressing rapidly, but the liquid crystal module (LCM) assembly technology and materials used in the back-end are also increasingly sophisticated. Various LCD module makers are competing to launch models with larger sizes, and also continue to launch models with more reasonable prices to meet market demand. Therefore, with a large amount of production capacity released, LCD manufacturers must continue to improve and innovate in module materials, design, and assembly me...
