Provided are a display panel and a driving method thereof, and a display device. A light emission control transistor of a pixel driving circuit in the display panel is connected in series between the anode of a light-emitting element and a first power signal line. A cathode switch transistor is connected in series between the cathode of the light-emitting element and a second power signal line. In at least one light emission stage, the time when the cathode switch transistor is turned on lags behind the time when the light emission control transistor is turned on.

Display panel and driving method thereof, and display device

A display panel and a display device are provided. The display panel includes a fingerprint identification area, at least one support unit, and a pixel definition layer. The fingerprint identification area includes a light-transmitting area and a non-light-transmitting area. The support unit is disposed in the light-transmitting area and the non-light-transmitting area. The pixel definition layer includes a plurality of aperture areas each exposing at least one light-emitting unit. Each aperture area has a first neighboring side adjacent to a support unit having a second neighboring side disposed opposite to the first neighboring side. The second neighboring side has an effective length that is parallel to and directly facing the first neighboring side, and the effective length is smaller than a length of the first neighboring side; or, the support unit is disposed adjacent to the first neighboring side, which is a short side of the aperture area.

Display panel and display device

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.
