Embodiment Construction

[0021] In order to make the examiners have a further understanding and understanding of the structural features of the present invention and the effects achieved, I would like to add preferred embodiments and cooperate with detailed descriptions, and the descriptions are as follows:

[0022] The conventional direct type backlight module includes a reflective sheet, a plurality of light sources, a light diffusion plate, a lower diffusion film, a prism sheet and an upper diffusion film, and then the optical sheets are combined together, which not only increases the time required for assembly. Therefore, the present invention provides a light diffusion plate that increases light diffusion and improves brightness, so as to reduce the structure of the direct type backlight module and reduce the manufacturing cost.

[0023] Please refer to FIG. 2 , which is a schematic structural diagram of a light diffusing plate according to a preferred embodiment of the present invention. Wherein...

Abstract

A light diffusion plate for increasing light diffusion and for increasing light brightness is prepared for arranging an optical lens and a diffusion layer at one side of base plate, setting said diffusion layer above said optical lens for intensifying diffusion effect, using a plane or micro-lens as light incoming surface at another side of said light diffusion plate. The prepared light diffusion plate can be used in back light module of LCD TV.

Description

Technical field: [0001] The present invention relates to a diffuser plate for a direct type backlight module, in particular to a light diffuser plate for increasing light diffusion and improving brightness. Background technique: [0002] Nowadays, multimedia technology is advancing by leaps and bounds, mostly benefiting from the rapid development of semiconductor components or display devices. As far as displays are concerned, Cathode Ray Tube (CRT) has been monopolizing displays in recent years due to its excellent display quality and economy. market. However, considering the environment of personal computer displays, or from the viewpoint of environmental protection, if we speculate on the trend of energy saving, the cathode ray tube may have many problems due to space utilization and energy consumption. And the need for low power consumption cannot effectively provide a solution. Therefore, Thin Film Transistor Liquid Crystal Display (TFT-LCD) with superior characterist...
