Abstract

The invention discloses a miniature LED display panel, a manufacturing method thereof and a display device. The miniature LED display panel comprises a miniature LED array board and a driving substrate arranged opposite to each other; the miniature LED array board includes a plurality of miniature LEDs, the miniature LED includes a first electrode layer, a second electrod elayer and a plurality offunctional layers, the plurality of functional layers are located between the first electrode layer and the second electrode layer, the second electrode layer is located at one sides of the pluralityof functional layers away from the driving substrate, a groove is arranged between two adjacent miniature LEDs, a side face of the groove exposes at least part of the functional layers, and a light-absorbing material is arranged in the groove. The miniature LED display panel provided by the invention can reduce the lateral light leakage of the miniature LEDs, reduce the risk of display color mixing caused by occurrence of optical crosstalk between pixels, and improve a display effect.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a micro-LED display panel, a manufacturing method thereof, and a display device. Background technique [0002] Light-emitting diodes (for example, Organic Light-Emitting Diode (OLED for short), Micro Light-Emitting Diode (Mic-LED for short)) as a current-type light-emitting device, with their active light emission and fast response speed , wide viewing angle, rich colors, high brightness, low power consumption and many other advantages are widely used in the display field. [0003] At present, the micro-LED display panel, a display that realizes image display by integrating high-density micro-sized LED arrays on the substrate as display pixels, has gradually entered people's lives. The inventors found that there are problems such as optical crosstalk and color mixing between pixels in the existing micro-LED display panel, which affect the display effect. [00...
