Abstract
A micro LED display panel defines a display area and a border area surrounding the display area. The micro LED display panel includes a TFT array substrate, a plurality of micro LEDs on the TFT array substrate, a common electrode on the TFT array substrate, the common electrode covering and electrically coupling to all of the micro LEDs; a metal layer on a side of the common electrode away from the TFT array substrate and electrically coupling to the common electrode, and a black photoresist layer on a side of the metal layer away from the TFT array substrate. The black photoresist layer defines through holes. Each through hole extends through both the black photoresist layer and the metal layer and aligns with one micro LED. The metal layer and the black photoresist layer cover the display area and the border area.
