Display device, wearable display device and method for determining gaze positions

A wearable display device, comprising:

• a display device, a lens disposed on a display side of the display device, and a plurality of light-emitting elements disposed on an edge of the lens;
• wherein
• the display device comprises:
• a display panel, comprising 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;
• and
• a plurality of photoelectric sensor assemblies, each of the photoelectric sensor assemblies being provided with a strip-shaped photosensitive region;
• wherein one portion of the plurality of photoelectric sensor assemblies are disposed in the first region, extension directions of the photosensitive regions of the portion of the photoelectric sensor assemblies being parallel to the second direction;
• the other portion of the photoelectric sensor assemblies are disposed in the second region, extension directions of the photosensitive regions of the other portion of the photoelectric sensor assemblies being parallel to the first direction;
• and 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;
• and
• emitting directions of the plurality of light-emitting elements face away from the display device.

A method for determining gaze positions, applicable to a display device, wherein the display device comprises:

• a display panel, comprising 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;
• and
• a plurality of photoelectric sensor assemblies, each of the photoelectric sensor assemblies being provided with a strip-shaped photosensitive region;
• wherein one portion of the plurality of photoelectric sensor assemblies are disposed in the first region, extension directions of the photosensitive regions of the portion of the photoelectric sensor assemblies being parallel to the second direction;
• the other portion of the photoelectric sensor assemblies are disposed in the second region, extension directions of the photosensitive regions of the other portion of the photoelectric sensor assemblies being parallel to the first direction;
• and 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;
• and
• the method comprises:
• receiving a first electric signal transmitted by the photoelectric sensor assembly within the first region, wherein the first electric signal is converted, by the photoelectric sensor assembly within the first region, from a first optical signal reflected via eyes of a user;
• receiving a second electric signal transmitted by the photoelectric sensor assembly within the second region, wherein the second electric signal is converted, by the photoelectric sensor assembly within the second region, from a second optical signal reflected via the eyes of the user;
• and
• determining a gaze position of the eyes of the user on a display panel based on the first electric signal and the second electric signal.
