Abstract

The invention provides a Mini LED backlight structure and a display device. The Mini LED backlight structure comprises an array substrate, a distributed Bragg reflector layer and a plurality of LED light emitting units, wherein the distributed Bragg reflector layer is arranged on the array substrate and comprises a plurality of first reflecting film layers and a plurality of second reflecting filmlayers, the first reflecting film layers and the second reflecting film layers are alternately stacked to form the distributed Bragg reflector layer, and the refractive index of the first reflectingfilm layers is greater than that of the second reflecting film layers; the distributed Bragg reflector layer is provided with a plurality of mounting holes penetrating to the array substrate; and theplurality of LED light emitting units are arranged on the array substrate and are located in the mounting holes. According to the invention, the reflectivity of light emitted by the LED to the substrate can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a Mini LED backlight structure and a display device. Background technique [0002] LED, the full name of Light Emitting Diode, is considered to be a powerful representative of the next-generation display technology due to its wide color gamut, low power consumption, and stability. In order to achieve the purpose of display, LED size must be very small to achieve high resolution requirements. At present, Micro LED cannot be mass-produced due to problems such as the difficulty of mass transfer. Mini LED came into being, using Mini LED as backlight and driving through array to realize dynamic regional dimming, also known as Local Dimmy technology, so as to achieve high contrast of LCD screen and greatly improve image quality. Mini LED backlight has the advantages of high brightness and low power consumption. In order to improve the light utilization rate of LED, it is ...
