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.
