Abstract

The invention provides a micro light-emitting diode display panel. The display panel comprises a substrate, at least one light-emitting unit, a reflecting layer and a light absorbing layer. The at least one light-emitting unit is arranged on the substrate to define at least one pixel, and each light-emitting unit comprises a plurality of micro light-emitting diodes. The reflecting layer is arranged on the substrate and located between the micro light-emitting diodes, the reflecting layer is provided with a plurality of concave cavities surrounding the micro light-emitting diodes, and the thickness of the reflecting layer close to any micro light-emitting diode is larger than the thickness of the reflecting layer away from the corresponding miniature light-emitting diode. The light absorbing layer is at least arranged in the concave cavities of the reflecting layer. The micro light-emitting diode display panel has high contrast and high brightness.

Description

technical field [0001] The invention relates to a display panel, in particular to a micro light emitting diode display panel. Background technique [0002] In order to increase the contrast ratio of the existing micro-LED display panel, black barriers are filled in the gaps between the micro-LEDs, but this design will greatly reduce the brightness of the panel. Contents of the invention [0003] The invention provides a micro LED display panel with high contrast and high brightness. [0004] A micro light-emitting diode display panel of the present invention includes: a substrate, at least one light-emitting unit, a reflective layer and a light-absorbing layer. At least one light-emitting unit is arranged on the substrate to define at least one pixel, and each light-emitting unit includes a plurality of miniature light-emitting diodes. The reflective layer is disposed on the substrate and is located between each micro-LED, wherein the reflective layer has a plurality of ...
