Embodiment Construction

[0036] FIG. 3 is a cross-sectional view of the backlight module of the present invention, and FIG. 4 is an exploded perspective view of the backlight module of FIG. 3 . Please refer to FIG. 3 and FIG. 4 at the same time, the backlight module 200 includes a diffusion plate 210 , a frame 220 and at least one light source 230 . The frame 220 is disposed on one side of the diffusion plate 210 , wherein the diffusion plate 210 is placed on the frame 220 . The frame 220 has a wave-shaped bottom plate 222 and a side plate 224 , wherein the wave-shaped bottom plate 222 is connected to the side plate 224 . In this embodiment, the wave-shaped bottom plate 222 and the side plate 224 are integrally formed, and the material of the wave-shaped bottom plate 222 may be resin. In addition, the corrugated bottom plate 222 and the side plate 224 may not be integrally formed. In other words, the side plate 224 can be made of metal or other materials, and the side plate 224 can be connected to t...

Abstract

A backlight module is prepared as setting frame at one side of diffusion plate and forming said frame by a wave shaped base plate and a side plate, setting multiple light source support seat on wave shaped base plate and integrating said seats with said base plate to be a unified body, setting light source between wave shaped base plate and diffusion plate.

Description

technical field [0001] The invention relates to a display, and in particular to a backlight module of the display. Background technique [0002] With the development of technology, digital tools such as mobile phones, digital cameras, digital video cameras, notebook computers and desktop computers are all becoming more convenient and multifunctional. And beautiful direction development. When using these information products, the display screen is an indispensable human-machine communication interface. Through the display function of the display screen, the user can operate the product more conveniently. Liquid crystal displays have become the mainstream of display screens due to their advantages of power saving and low radiation. However, since the liquid crystal display panel of the liquid crystal display itself cannot emit light, a backlight module must be provided under the liquid crystal display panel to provide a light source to achieve the display function.
