Embodiment Construction

[0015] The main idea of ​​this embodiment is to propose a backlight module and its diffuser plate and a flat-panel display using it. The diffuser plate of the backlight module is clamped to the design of the metal back frame through the fixing part, and not only can be fixed on the metal back frame without a plastic frame. In the back frame, the effect of carrying optical sheets and display panels can be achieved. A group of preferred embodiments are taken as examples to describe in detail below, but the following words and icons are for illustration purposes only, and will not limit the intended protection scope of the present invention.

[0016] Please refer to Figure 3A and Figure 3B , Figure 3A A three-dimensional exploded view showing a flat panel display according to a preferred embodiment of the present invention, Figure 3B draw Figure 3A Cross-sectional view of the middle backlight module after assembly. Such as Figure 3A As shown, the flat panel display 20...

Abstract

The present invention discloses a backlight module, which comprises a metal back frame, a light source, a diffusion plate and at least one optical blank sheet. The metal back frame is provided with a top opening and a bottom surface corresponding to the opening; the light source is arranged on the bottom surface of the metal back frame; the diffusion plate comprises a diffusion plate body, a fixing part and a protruding part, and is provided with an upper surface and a periphery; the fixing part is arranged at the periphery of the diffusion plate body; the protruding part protrudes out of theupper surface of the diffusion plate body and forms a holding space together with the upper surface; the fixing part is used for fixing the diffusion plate on the metal back frame; and the optical blank sheet is positioned in the holding space. The present invention adopts the design with the diffusion plate clamped and connected with the metal back frame through the fixing part, and thus achieving the effects of bearing the optical blank sheet and displaying the panel.

Description

technical field [0001] The present invention relates to a backlight module and its diffuser plate and a flat display using the same, and in particular to a backlight module in which the diffuser plate can be fixed to a metal back frame and a flat display using the same. Background technique [0002] With the development of liquid crystal display (Liquid Crystal Display, LCD) manufacturing technology, its advantages such as thinness, power saving and low radiation have gradually made liquid crystal display widely used in various electronic products such as LCD TVs and digital cameras. In recent years, it has replaced The cathode ray tube (Cathode Ray Tube, CRT) monitor was introduced and became the standard equipment of computer screen. However, at present, the display panel in the liquid crystal display is a non-self-illuminating display panel, which requires a backlight module to provide a backlight to perform the display function. [0003] Please refer to figure 1 , whic...
