Abstract

The invention discloses a backlight source, a manufacturing method thereof, and a display device, and belongs to the technical field of display. The backlight source includes: a light guide plate and a light-emitting unit arranged on one side of the light-incident surface of the light-guide plate; Unit corresponding settings. The invention solves the problem in the related art that the overall structure of the backlight source is limited by the distance between the LED and the first layer of diffusion sheet, and the product cannot be made lighter and thinner. The invention is used in the manufacture of backlight sources.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source, a manufacturing method thereof, and a display device. Background technique [0002] A liquid crystal display (English: Liquid Crystal Display; LCD for short) includes a liquid crystal display panel and a backlight arranged on the back of the liquid crystal display panel. Existing backlights include side-type backlights and direct-type backlights. Compared with the side-lit backlight, the direct-lit backlight can be combined with local backlight adjustment (English: Local Dimming) technology for local dimming, so as to reduce the power consumption of the backlight and improve the display contrast of the LCD. [0003] In the related art, direct-lit backlights capable of regional dimming such as figure 1 As shown, it includes a first layer of diffusion sheet 101, a second layer of diffusion sheet 102 and a third layer of diffusion sheet 103, and the direct type...
