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 panel comprises:
• a display region and a peripheral region surrounding the display region:
• a plurality of photoelectric sensor assemblies, disposed in the peripheral region, wherein 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
• a processing circuit, connected to each of the photoelectric sensor assemblies, wherein the processing circuit is configured determine a gaze position of the eyes of the user on the display panel based on a signal value of the electric signal transmitted by each of the photoelectric sensor assemblies and a position of at least one of the photoelectric sensor assemblies;
• and
• light-exiting 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 and a peripheral region surrounding the display region;
• a plurality of photoelectric sensor assemblies, disposed in the peripheral region, wherein 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
• a processing circuit, connected to each of the photoelectric sensor assemblies, wherein the processing circuit is configured determine a qaze position of the eyes of the user on the display panel based on a signal value of the electric signal transmitted by each of the photoelectric sensor assemblies and a position of at least one of the photoelectric sensor assemblies:
• the method comprising:
• receiving an optical signal reflected via eyes of a user;
• converting the optical signal into an electric signal;
• and
• determining a gaze position of the eyes of the user on a display panel based on a signal value of the electric signal and a position of at least one photoelectric sensor assembly.
