Description

technical field [0001] The present invention relates to the field of display technology, in particular to a micro LED display panel. Background technique [0002] Micro-LED (Micro Light Emitting Display), also known as micro LED or μLED, is an emerging flat panel display technology. At present, a micro LED display panel usually includes a layered N-type doped inorganic light-emitting material layer and a P-type doped inorganic light-emitting material layer, and a transparent conductive film layer ( as cathode), a metal layer (as anode) connecting said P-doped phosphor layer. However, current micro LED display panels are generally not provided with in-cell touch sensing electrodes. SUMMARY OF THE INVENTION [0003] In view of the above, the present invention provides a micro LED display panel, which includes: [0004] The transparent conductive layer, the micro LED layer and the first metal layer are stacked in sequence; [0005] The micro LED layer includes a plurality...
