Abstract

The invention provides a display device and a backlight module. The backlight module comprises a circuit board, multiple mini LEDs (light emitting diodes), a protective adhesive layer covering the multiple mini LEDs and the circuit board, a transparent substrate arranged on one side, deviating from the circuit board, of the protective adhesive layer and a diffusing plate arranged on one side, deviating from the circuit board, of the transparent substrate, wherein the thickness of the transparent substrate meets mixed light distances of the mini LEDs. The transparent substrate serves as a support structure between the protective adhesive layer and the diffusing plate, so that light emitted by the mini LEDs is sufficiently mixed before reaching the diffusing plate, and the backlight illumination effect is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a display device and a backlight module. Background technique [0002] High-Dynamic Range display technology (High-Dynamic Range, referred to as HDR), can provide more dynamic performance and image details, can better reflect the visual effects of objects in the real environment, and is generally considered to cause display The next revolution in the field. At the same time, HDR technology also puts forward higher requirements for LCD terminals - finer partition control and contrast. [0003] The size of a micro light emitting diode (mini LED) is about 50 μm-300 μm. Using a huge number of mini LED grains as a backlight source in the field of liquid crystal display can not only realize the thinning of the backlight module, but also achieve more refined dynamic control and improve the dynamic contrast of the liquid crystal display. [0004] In a traditional direct-lit backl...
