Abstract: A display panel includes a display substrate. The display substrate includes: a base substrate; a display structure layer including a plurality of pixel circuits and a plurality of light-emitting devices on the base substrate; and a light detection layer located at a non-light exit side of the light-emitting devices. A pixel circuit in the plurality of pixel circuits is electrically connected to a respective light-emitting device to drive the light-emitting device to emit light. The light detection layer is configured to detect a luminous intensity of at least one light-emitting device. The display substrate further includes: a transparent cover plate at a light exit side of the light-emitting devices; and a polarizer and a first quarter-wave plate between the display substrate and the transparent cover plate. The polarizer is closer to the display substrate than the first quarter-wave plate.
