Problems solved by technology

In particular, as consumer demand for ultra-thin display products is increasing, in order to keep pace with this trend, research is in full swing to minimize the number of diffusers that can be placed on the rear of the display panel by about 3 to 5 , this type of display products may have the following problems, for example, the brightness uniformity of the output image is reduced due to the inability to guarantee the light diffusion degree originally responsible for the diffusion sheet, thereby aggravating hot spots

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 display and a light guide plate thereof. More particularly, the present invention relates to a display with improved brightness uniformity and a light guide plate thereof. Background technique [0002] Backlight module (BLU:BackLightUnit) refers to a kind of light source device located behind the screen of the liquid crystal display and used to provide light, which not only directly affects the brightness, color reproduction, viewing angle, contrast, readability and other image quality of the image And power consumption, product life, etc., and its price also accounts for about 20-50% 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 light source directly behind the screen to the LCD panel, while the edge-li...
