The invention relates to a micro LED light-emitting display array pixel
unit structure and a fabrication method thereof. The micro LED light-emitting display array pixel
unit structure comprises a display pixel unit body, wherein the display pixel unit body comprises a light-emitting
diode, a light-emitting
diode driving circuit and a lead, wherein the light-emitting
diode is manufactured by integration of an epitaxial
wafer grown on a substrate, and the lead is used for connecting the outside. Three parts required by manufacturing of the display pixel unit are integrated with the epitaxial
wafer by a
semiconductor processing technology, the pixel light-emitting unit and the
control circuit are integrated, so that the
welding process with complicated process and low reliability is omitted,the fabrication process is simple, and active driving of a micro
LED display array can be achieved without independently fabricating a pixel
driving circuit; and moreover, the integration density andthe reliability of the micro
LED display array are effectively improved, the display effect with high-speed scanning,
high definition and high quality can be achieved, the demand of next-generation display application is satisfied, and industrialization is promoted.
