Abstract
A display panel and fabrication method, and a display device are provided. The display panel includes a base substrate and a plurality of first units formed over the base substrate. A first unit includes an organic light-emitting diode, a fingerprint recognition unit, and a first micro-cavity. The organic light-emitting diode includes an anode, a cathode disposed opposite to the anode, and an organic light-emitting layer disposed between the anode and the cathode. The display panel also includes a plurality of first film layers formed over the base substrate. A first film layer is disposed between two adjacent mutually insulated anodes. The cathode covers the anode and the first film layer, and the first micro-cavity is formed between the first film layer and the cathode. The fingerprint recognition unit is disposed over a side of the first film layer away from the cathode.
