Abstract: A display panel includes a display layer, a photosensitive layer and an infrared mask. The display layer is configured to display an image, the display layer has light-transmitting portions, and the light-transmitting portions are configured to transmit infrared light. The photosensitive layer is disposed on a side of the display layer. The infrared mask is disposed on a side of the photosensitive layer proximate to the display layer, the infrared mask has hollowed-out regions, the hollowed-out regions are configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions is configured to prevent transmission of the infrared light. The photosensitive layer is configured to receive infrared light passing though the hollowed-out regions and the light-transmitting portions, and convert the infrared light into an image signal.
