Embodiment Construction

[0034] FIG. 2 is a schematic diagram of a backlight module according to a preferred embodiment of the present invention. Please refer to FIG. 2 , the backlight module 200 includes a light box 210 , a plurality of light sources 220 and an isolation structure 230 . Wherein, the light source 220 is disposed in the light box 210 , which is, for example, a cold cathode fluorescent tube or an array of light emitting diodes. In addition, the isolation structure 230 is disposed at the bottom of the light box 210 and is located between two adjacent light sources 220, wherein the horizontal cross-sectional area of ​​the higher position of the isolation structure 230 is, for example, smaller than the horizontal cross-sectional area of ​​the lower position of the isolation structure 230 , and the reflectance at higher positions on the surface of the isolation structure 230 is smaller than the reflectance at lower positions on the surface of the isolation structure 230 . In this embodimen...

Abstract

A back light module is prepared as setting multiple light source in lamp box and isolation structure at bottom of lamp box in between two adjacent light sources, making reflectivity at upper position of surface on isolation structure be less than reflectivity at lower position of surface on isolation structure.

Description

technical field [0001] The invention relates to a light source module, in particular to a backlight module capable of providing uniform backlight in a liquid crystal display. Background technique [0002] With the high development of multimedia technology, most of the transmission of video information has now been converted from analog to digital transmission, and the volume of video or video devices is also becoming thinner and thinner. Although the traditional cathode ray tube (Cathode Ray Tube, CRT) display has the advantages of excellent display quality and low cost, due to the structure of its internal electronic cavity, the display cannot meet the requirements of thinning, light weight and low power consumption. And there are also problems such as radiation damage eyes when the user watches. Therefore, as optoelectronic technology and semiconductor manufacturing technology tend to mature, flat panel displays (Flat Panel Displays) will flourish, and liquid crystal disp...
