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 containing the light guide plate and a display device, and more particularly relates to a light guide plate capable of improving light diffusion, a backlight module containing the light guide plate and a display device. 【Background technique】 [0002] Backlight module (BLU: Back Light Unit) is a kind of light source device that provides light to the rear of the screen of the liquid crystal display device. It not only directly affects the brightness of the image screen, color reproduction, viewing angle, light-dark ratio, and readability Image quality, power consumption, product life and other parameters will also be affected, and the backlight module is a core component whose cost accounts for about 20% to 50% of the cost of the entire liquid crystal display device. [0003] Backlight modules can be roughly divided into direct-lit and edge-lit depending on the installation position of t...
