Problems solved by technology

However, adding the spring 250 will lead to an increase in cost, and the spring 250 must be assembled in the groove 214 at the same time as the support member 240, which will cause difficulty in assembly.
In addition, since the frame body 210 is provided with the groove 214 for accommodating the spring 250, this will make the sheet metal shape of the frame body 210 complicated, resulting in an increase in the cost of manufacturing the frame body 210.

Embodiment Construction

[0072] FIG. 3A is an exploded perspective view of a direct-type backlight module according to an embodiment of the present invention, and FIG. 3B is an enlarged view of the separation of the supporting member and the frame of FIG. 3A , and FIG. 3C is a part of the combined direct-type backlight module of FIG. 3A Sectional view. Please refer to FIG. 3A , FIG. 3B and FIG. 3C at the same time. The direct type backlight module 300 of the present invention includes a frame body 310 , a plurality of light sources 320 , a diffusion plate 330 and at least one supporting structure 340 . The light sources 320 are disposed in the frame body 310 , and the diffusion plate 330 is disposed above the light sources 320 , wherein the diffusion plate 330 is suitable for uniformizing the light emitted by the light sources 320 to convert the light into a uniform surface light source.

[0073] The frame body 310 has a bottom plate 312 , and at least one opening 314 is disposed on the bottom plate 3...

Abstract

Tne invention provides a down-backlight module, including frame body, a number of sources, the proliferation of boards and at least one supporting structure. Frame of a floor, and installed in the floor at least one hole. Source is installed at the box body, and the proliferations of light panels are installed at the top, and the supporting structure located in the proliferation between the plate and frame. Supporting structure including support columns, base, and at least one flexible fins. Supported through a hole column, and supporting the top and bottom of a column, which supports the proliferation suitable for the top plate and bottom of piercing the bottom of the frame. Based on the support link at the bottom of the column, and flexible fins with the support column connections is inconsistent with the bottom of the frame. So, because of the proliferation of outside board and wear due to down-backlight module can maintain a stable quality.

Description

technical field [0001] The invention relates to a light source module and a display device, and in particular to a direct-type backlight module and a liquid crystal display device. Background technique [0002] With the advancement of modern video technology, liquid crystal display devices have been widely used in the display screens of consumer electronic products such as mobile phones, notebook computers, personal computers and personal digital assistants. However, since the liquid crystal display panel itself of the liquid crystal display device does not have the function of emitting light, it is necessary to install a backlight module on the back of the liquid crystal display panel to provide the surface light source required by the liquid crystal display panel, and then make the liquid crystal display panel achieve the display effect. [0003] FIG. 1A is a stereoscopic perspective view of a known direct-type backlight module, and FIG. 1B is a partial cross-sectional vie...
