Abstract
Provided is a display device including a display panel and a plurality of photoelectric sensor assemblies. The display panel includes a display region, a first region disposed outside the display region and extending along a first direction, and a second region disposed outside the display region and extending along a second direction, wherein the first direction is intersected with the second direction. Each of the photoelectric sensor assemblies is provided with a strip-shaped photosensitive region. One portion of the plurality of photoelectric sensor assemblies are disposed in the first region, the other portion of the photoelectric sensor assemblies are disposed in the second region. Each of the photoelectric sensor assemblies is configured to receive an optical signal reflected via eyes of a user and convert the optical signal into an electric signal.
