Embodiments of the present invention provide a micro light-emitting diode display panel and a display device. By multiplexing a metal layer as a touch electrode, the space utilization rate of the display panel is improved, which is beneficial to the light and thin design of the display panel. The micro-light-emitting diode display panel includes a plurality of light-emitting elements distributed in a matrix, and each light-emitting element includes a first electrode, a semiconductor layer and a second electrode stacked, and the semiconductor layer is located between the first electrode and the second electrode; the semiconductor layer It includes a first semiconductor layer, an active layer and a second semiconductor layer stacked in sequence; each light-emitting element also includes a metal layer, the metal layer surrounds the side of the semiconductor layer, the metal layer and the first electrode are insulated from each other, and the metal layer and the second electrode are insulated from each other. The electrodes are insulated from each other; multiple light emitting elements are divided into multiple light emitting element groups, and each light emitting element group includes multiple light emitting elements; metal layers in the multiple light emitting elements in each light emitting element group are connected to each other to form a touch electrode.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to a micro light emitting diode display panel and a display device. 【Background technique】 [0002] Micro-LED (Micro-LED) technology refers to the technology of micro-sized light-emitting diode (Light Emitting Diode, LED) arrays integrated with high density on the substrate. The size of each Micro-LED is only about 1 to 10 μm. This technology can form a high-resolution Micro-LED display panel. Micro-LED has the advantages of high luminous efficiency, low energy consumption and high resolution. [0003] In the current Micro-LED display panel, in order to realize the touch function, the touch electrode needs to be provided separately, and the separately provided touch electrode will occupy a large space, which is not conducive to the light and thin design of the display panel. 【Content of invention】 [0004] In view of this, the embodiments of the present invention provide a mic...
