Zusammenfassung: | The utility model discloses a display device, which comprises a lower substrate, an upper substrate and a cover plate which are sequentially overlapped from bottom to top, a light sensing unit is arranged above the lower substrate outside a display area, and the light sensing unit is electrically connected with the lower substrate. Because the light sensing unit is arranged on the lower substrate outside the display area, when external ambient light changes, amorphous silicon or PIN junctions in the light sensing pixels show different current changes, and meanwhile, a light sensing function can be integrated in the display screen through a corresponding driving algorithm, so that light sensing and distance sensing functions are further realized, and the display screen is convenient to use. The photosensitive unit can be synchronously manufactured by using an LCD/OLED process, and a hole does not need to be independently formed in the cover plate, so that a driving IC (Integrated Circuit) can be saved, the pro |
