Abstract: A display panel and the display device are provided in the present disclosure. The display panel includes a photosensitive display circuit. The photosensitive display circuit includes a light-emitting diode, a pixel driving circuit, and a photosensitive circuit. By multiplexing the light-emitting diode, can not only achieve normal display function under the condition that the light-emitting diode is forward biased, but also achieve light detection according to the photo-generated current following through the light-emitting diode under the condition that the light-emitting diode is reverse biased or no biased. This alleviates the need for an additional light sensor, thereby reducing the cost and size of the display product.
