Problems solved by technology

[0004] However, at present, the height of the lens used with the LED reaches about 5mm, and the ultra-thin backlight design cannot be realized; and if the lens is removed, the backlight cannot achieve better uniformity. In order to improve the uniformity of the backlight, the LED has to be greatly increased. Use quantity, resulting in an increase in production costs

Abstract

The invention discloses a display device. The display device comprises a micro LED lamp panel and an angle selection layer located on the light-emitting side of the micro light-emitting diode lamp panel, the angle selection layer reflects light in a first incident angle range and transmits light in a second incident angle range, and an incident angle value corresponding to the first incident anglerange is smaller than an incident angle corresponding to the second incident angle range. A light reflecting layer on the micro light-emitting diode lamp panel can perform diffuse reflection on lightreflected by the angle selection layer and input the light to the angle selection layer again, so that the diffusely reflected light with the second incident angle is transmitted, the light with thefirst incident angle continues to repeat reflection, and finally, the light intensity distribution of a backlight module is uniform.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] As the current mainstream display screen, liquid crystal display has the advantages of low power consumption, small size, and low radiation. The liquid crystal display panel is a non-self-illuminating panel and needs to be used in conjunction with a backlight module. [0003] The current direct-type backlight module usually uses a light emitting diode (Light Emitting Diode, LED for short) as a backlight source, which has the advantages of high brightness of the backlight and no decrease in brightness after long-term use. The outgoing light of the LED is distributed in a Lambertian shape. In order to expand the irradiation range of the LED spot, LEDs are usually combined with a lens to increase the brightness of the large-angle outgoing light of the LED. [0004] However, at present, the height of the lens used with the LE...
