Abstract

The invention discloses a side-light type backlight and a display device. The side-light type backlight is capable of achieving obvious optical partitions of the scanning backlight technology. The backlight comprises a back plate, light sources and light pipes, a plurality of mutually parallel grooves are arranged on the back plate, one light pipe is arranged in each groove, and each light source is arranged at least one end of each light pipe.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an edge-light backlight source and a display device. Background technique [0002] In the field of liquid crystal display technology, a liquid crystal display (Liquid Crystal Display, LCD) itself does not emit light, and a backlight source is usually provided on the back of the LCD to realize image display. [0003] According to the installation position of the light source in the backlight, the backlight can be divided into a direct type and an edge type. The feature of the edge-lit backlight is that the light source is arranged on the edge of the backplane, and the light emitted by the light source directly enters the light guide plate, and the light guide plate forms a surface light source covering the entire backplane from the light from the light source. The feature of the direct type backlight is that the light source is tiled on the entire backplane. The l...
