Abstract

The invention provides a micro light-emitting diode display panel, a preparation method thereof and a display device. The micro light-emitting diode display panel comprises a micro light-emitting diode binding area, a shading area and a peripheral wiring area, and the micro light-emitting diode display panel further comprises a substrate, a first metal layer located on the substrate, an interlayer insulating layer located on the first metal layer and a second metal layer located on the interlayer insulating layer. An anti-reflection layer used for reducing the reflectivity of the second metal layer is arranged on the second metal layer and corresponds to the micro light-emitting diode binding area and the peripheral wiring area. According to the anti-reflection layer provided by the invention, the reflection of the second metal layer to ambient light can be reduced, the contrast ratio of the micro light-emitting diode display panel is improved, and the display quality of the micro light-emitting diode display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a micro-light-emitting diode display panel, a preparation method thereof, and a display device. Background technique [0002] MLED (Micro, Mini Light Emitting Diode, Micro Light Emitting Diode) is a new generation of display technology, which has higher brightness, better luminous efficiency and lower power consumption than the existing OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology. low, and thus received widespread attention. Large-sized micro-LED display panels are mainly formed by splicing multiple small-sized micro-light-emitting diode display panels, and multiple small-sized micro-light-emitting diode display panels are provided with a plurality of metal wiring pads in the peripheral wiring areas, so that large There are many splicing gaps in micro light-emitting diode display panels of small size. [0003] In addition, the micro-lig...
