Abstract

The embodiment of the invention provides a micro-light-emitting-diode display panel and a display device. With a composite metal layer as a touch electrode, the space utilization rate of the display panel is improved and the lightening and thinning design of the display panel is realized. The micro-light-emitting-diode display panel comprises a plurality of light emitting elements arranged in a matrix. Each light emitting element consists of a first electrode, a semiconductor layer and a second electrode that are laminated successively; and the semiconductor layer is arranged between the first electrode and the second electrode. Each semiconductor layer includes a first semiconductor layer, an active layer and a second semiconductor layer that are laminated successively. In addition, each light emitting element also includes a metal layer encircling the side of the semiconductor layer; the metal layer and the first electrode are insulated with each other and the metal layer and the second electrode are insulated with each other. The plurality of light emitting elements are divided into a plurality of light emitting element groups, each of which includes a plurality of light emitting elements; and the metal layers of the plurality of 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...
