Abstract: Provided are a display panel and a display device. The display panel has a display region and includes a substrate, light-emitting elements located in the display region, pixel circuits, and at least one driving circuit. The light-emitting elements, the pixel circuits and the at least one driving circuit are located at a side of the substrate. The light-emitting elements are connected to the pixel circuits, and each driving circuit includes shift registers. The pixel circuits includes at least one first pixel circuit including a first driving circuit, and the at least one first pixel circuit and at least one shift register are located in the display region. In the display region, the at least one first pixel circuit is arranged at a side of the shift registers of the first driving circuit close to an edge of the display panel.

Abstract: A display panel and a display device are provided. The display panel is a flexible bendable or foldable display panel. In order to improve the anti-bending performance of a bending region, a flexible thin-film encapsulation unit in the bending region is divided into a plurality of first thin-film encapsulation units and a plurality of second thin-film encapsulation units extending in a direction of the bending axis, thereby solving the problems of a large stress caused by the integrated encapsulation units in the original bending region, and a poor anti-bending performance caused thereby.

Abstract: A display panel and a display apparatus are provided. An exemplary display panel includes a display area having light-emitting areas and non-light-emitting areas and divided into a fingerprint identification area and a non-fingerprint identification area; an array layer including pixel driving circuits; a display layer disposed on a side of the array layer adjacent to a light-emitting surface of the display panel and including light-emitting devices; and a light-sensing device disposed in the fingerprint identification area and the non-light emitting area. A number of the light-emitting devices in an unit area in the fingerprint identification area is smaller than that in the unit area of the non-fingerprint identification area; and under a same gray scale driving signal, an absolute value of a difference N between a brightness of the fingerprint identification area and a brightness of the non-fingerprint identification area is smaller than or equal to 100 nit.
