Problems solved by technology

[0004] However, since the Mini LED emits light from both the front and the side, only the light emitted from the front can be used for backlighting, and the emitted light from the light source cannot be fully utilized, and the uniformity of the emitted light needs to be improved.

Abstract

The invention discloses a display device which comprises a backlight module and a display panel, wherein a Mini LED lamp panel in the backlight module comprises a driving substrate, a miniature light emitting diode, a first reflecting coating and a second reflecting coating. According to the invention, a circle of first reflecting coating is arranged in the area nearby the miniature light emitting diode, light emitted from the side surface of the Mini LED to one side of the driving substrate can be received, the light is reflected to the light emitting side of the Mini LED lamp panel again, so that the utilization efficiency of the emergent light of the Mini LED is improved. The second reflecting coating is arranged in the areas, except for the Mini LED and the first reflecting coating, of the driving substrate, and the incident light can be subjected to diffuse reflection, so that the light emitted by the Mini LED is fully mixed, and then the light emitted by the Mini LED lamp panel is relatively uniform.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the development of display technology, liquid crystal display technology is widely used in the display field. The liquid crystal display panel itself cannot emit light, and needs a backlight module to provide the required brightness for its display. However, due to the limitations of the characteristics of the liquid crystal panel itself, light leakage occurs to varying degrees, and there is a bottleneck in the improvement of contrast. [0003] Mini Light Emitting Diode (Mini LED for short) as a backlight has become a current hot spot in liquid crystal display technology. Mini LED can be applied to dynamic sub-area adjustment technology to achieve high dynamic contrast display effect. In addition, Mini LED is smaller in size than traditional light sources, which can reduce the thickness of the backlight module and re...
