Back light system

Abstract

The invention is a kind of light-back system, which includes a light board and a source, the light board contains an entrance face, a back surface and a exit face, the entrance face is used to receive the beam, the back surface connects with the entrance face, the exit face opposites to the back surface, which is used to guide the beam out of the light board, the source is set at one side of the entrance face. There sets many mesh spots and V type slots on the back surface, the exit surface has many even ladder type prisms structure. The prisms gather the exit lights in order to enhance the density of the exit beam of light board.

Description

【Technical field】 [0001] The invention relates to a backlight system for a liquid crystal display. 【Background technique】 [0002] At this stage, liquid crystal displays are widely used in notebook computers, desktop computers, workstations, industrial monitors, global satellite positioning systems (GPS), Personal data processing, game consoles, videophones, portable VCDs, DVDs and other portable devices. However, the liquid crystal itself does not emit light, and there must be a backlight system to provide it with the brightness required to display images. Moreover, the liquid crystal display panel is composed of a plurality of liquid crystal units, and each liquid crystal unit has the same requirement for bright light acquisition, so the backlight system must be a surface light source with uniform distribution of luminance. [0003] see figure 1 , is a prior art backlight system 100, which generally includes a light source 110, a light guide plate 120, a diffuser plate ...
