Abstract

The invention provides a support structure, a backlight unit and a display panel. The support structure is arranged in the backlight unit of the display panel. The backlight unit comprises a back plate, a backlight source, a support structure and a diffusion plate located above the support structure, wherein the backlight source and the support structure are arranged on the back plate. The bottomof the support structure is fixed on the back plate. The height of the support structure is greater than the height of the backlight source. A diffuse reflection structure is arranged on the surface of the part, which contacts the diffusion plate, of the support structure. According to the invention, the diffuse reflection device is arranged on the part, which is adjacent to the diffusion plate, of the top of the support structure, which can effectively divert light to a region at the top of the support structure to avoid formation of bright spots or shadows on the display panel.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to a support structure, a backlight unit and a display panel. Background technique [0002] Liquid crystal display technology is now widely used in many electronic products such as TVs, notebooks, mobile phones, and digital cameras. However, the liquid crystal panel itself does not emit light, and a backlight module (BLM) is needed to provide a surface light source with sufficient luminance and uniformity. Backlight units can be classified into edge-lit and direct-lit according to the position of the light source. [0003] The direct type backlight unit has the advantages of high cost performance and good optical stability. The basic structure of the direct-lit LED backlight unit includes an LED light source disposed at the bottom of the module, a diffuser plate disposed at the top of the module, and a support structure disposed between the LED light source and the diffuser plate...
