Abstract:
1. A display panel, comprising: image display elements disposed in an effective display area of a display screen, wherein the image display elements comprise liquid crystal elements, wherein the effective display area comprises a color filter layer of a plurality of colors; a first light-shielding layer disposed in a frame area around the effective display area, the first light-shielding layer transmitting invisible radiation while shielding visible light; a second light-shielding layer disposed in the effective display area, the second light-shielding layer transmitting invisible radiation while shielding visible light; and photo-detection elements disposed in the effective display area or in both of the effective display area and the frame area, wherein the photo-detection elements are disposed below the second light-shielding layer, the photo-detection elements detecting the invisible radiation, wherein a liquid crystal layer and a pair of electrodes applying a voltage to the liquid crystal layer are disposed in a region corresponding to the second light-shielding layer, thereby achieving a black display.
