Abstract

The invention is a backlight system, comprising a frame body, a light guide plate and at least a light source, where the frame body has a concave region with a mouth upward and at least a cavity connected with the concave region, the light source is arranged in the cavity, and the light guide plate is arranged in the concave region b the buried-in ejection forming technique, thus forming an integrated structure together with the frame body.

Description

【Technical field】 [0001] The invention relates to a backlight system, in particular to a backlight system for a liquid crystal display device. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display devices are widely used in modern information equipment such as notebook computers, mobile phones, and personal digital assistants. However, since the liquid crystal itself does not have luminous properties, it is necessary to provide a backlight system for it to realize the display function. [0003] see figure 1 , is a structural schematic diagram of a backlight system in the prior art. The backlight system 1 includes a light guide plate 4 , a light source 5 , a light source cover 6 , a reflection sheet 7 and a frame 8 . The light guide plate 4 includes two opposite light incident surfaces 4A, a light exit surface 4B, a bottom surface 4C and a plurality of side surfaces (not marked), the bottom surface 4...
