Abstract

The invention discloses a light-increasing structure of a backlight module, a backlight module and a display device to solve the problem of relatively serious light mixing in the gap between two adjacent partitions in the prior art. The light enhancement structure has a plurality of backlight partitions and a gap area between two adjacent backlight partitions, the light enhancement structure includes at least one prism layer, and the prism layer has a plurality of prisms arranged in parallel, The apex angle of the prism corresponding to the backlight partition is a first included angle, the apex angle of the prism corresponding to the gap area is a second included angle, and the angle of the second included angle is smaller than the first included angle. The angle of an included angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light enhancement structure of a backlight module, a backlight module and a display device. Background technique [0002] High dynamic range (High dynamic range, HDR) technology is more and more widely used in display because of its high dynamic contrast and better image quality display. To implement HDR technology, LCD monitors usually use Local dimming (local dimming) to adjust, that is, to adjust the backlight LED partitions, see figure 1 shown. Such as figure 1 As shown in , the display includes a plurality of rectangular backlight zones. [0003] Compared with ordinary backlight, Mini-LED has smaller LED lamp size and more partitions, such as figure 2 As shown in FIG. 2 , a schematic diagram of light emission of multiple Mini-LEDs (chips) of a display has made great progress in HDR technology. However, due to the small distance between two adjacent LEDs, the gap bet...
