Embodiment Construction

[0015] Please refer to FIG. 2 and FIG. 3 together, which are schematic diagrams of the first embodiment of the backlight system of the present invention. The backlight system 2 includes a frame body 20 , a light guide plate 21 and two light sources 22 . The frame body 20 is in the shape of a box, and its material is a highly reflective PC (Polycarbonate, polycarbonate) material with a reflectivity greater than 95%. The frame body 20 includes an upper surface 200 , a bottom surface 201 and a plurality of side surfaces 202 . In the center of the upper surface 200 of the frame body 20 there is a concave area 203 with an upward opening. Protruding points are provided on the surface, and the second space 205 is disposed on both sides of the first space 204 ; the light guide plate 21 is disposed in the first space 204 of the concave region 203 , and is integrally formed with the frame body 20 . The light guide plate 21 includes a light emitting surface 211 and two light incident su...

Abstract

The present invention relates to a backlight system, it includes a frame body, a light-conducting plate and at least one light source. Said frame body has a recessed region whose opening is upward, said recessed region has a first space and at least a second space, said second space in arranged close to said first space. Said light-conducting plate is placed in said first space of said recessed region, in which said light-conducting plate and said frame body are made into integrally-formed structure.

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 reflector 7 and a frame 8 . The light guide plate 4 mainly 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...
