Abstract

The present invention relates to a display device and a light guide plate thereof. According to an aspect of the present invention, there is provided a display device, including: a display panel configured to output an image to a front surface of the display device; a light source array arranged along at least one edge of the display device to output light; and a light guide plate arranged behind the display panel to guide light incident upon a side surface facing the edge from the light source array so that the light is projected through a front surface toward the display panel.

Description

technical field [0001] The invention relates to a light guide plate, a backlight module and a display including the light guide plate. More specifically, the present invention relates to a light guide plate with improved light diffusion, a backlight module and a display including the light guide plate. Background technique [0002] Backlight module (BLU: Back Light Unit) refers to a kind of light source device located behind the screen of the liquid crystal display and used to provide light. It can not only directly affect the brightness of the image, color reproduction, viewing angle, contrast, readability, etc. Image quality, power consumption, product life, etc., and its price accounts for about 20 to 50% of the total unit price of liquid crystal displays, so it is a core component. [0003] According to the arrangement of light sources, backlight modules can be roughly divided into direct-lit and edge-lit. The direct-lit backlight module uses the light emitted from the...
