Abstract: The present disclose provides a wearable display device and a method of determining a gaze position, relating to the field of virtual reality technology. Because the wearable display device has a high efficiency in processing electric signals transmitted by each of photoelectric sensor assemblies, the wearable display device may quickly determine the gaze position of eyes of a user on the display panel based on an electric signal transmitted by each of photoelectric sensor assemblies. In this way, the efficiency of displaying images by the display panel, and thus a higher refresh rate of the display panel is achieved.

Abstract: The present disclosure provides a display device, a wearable display device, and method for determining gaze positions, and relates to the field of virtual reality technologies. Because the display device has a high efficiency in processing an electric signal transmitted by each of photoelectric sensor assemblies is high, the display device is capable of quickly determining a gaze position of eyes of a user on a display panel based on the electric signal transmitted by each of the photoelectric sensor assemblies. In this way, the efficiency of displaying images by the display panel is further improved, and thus a higher refresh rate of the display panel is achieved.

Abstract: The present disclosure provides a wearable display device that relates to the field of virtual reality technology. Because the wearable display device has a high efficiency in processing electric signals transmitted via each of the photoelectric sensor assemblies, the wearable display device can quickly determine a gaze position of eyes of a user on the display panel based on an electric signals transmitted via each of the photoelectric sensor assemblies. In this way, the efficiency of the display panel in displaying images is improved, and the refresh rate of the display panel is higher. Moreover, as the photoelectric sensor assembly receives an optical signal, reflected via the eyes of the user, via a target structure in s lens assembly, it is possible to avoid the optical signal received by each of photoelectric sensor assemblies from being transmitted from different structures, ensuring the reliability of the optical signal received by each of photoelectric sensor assemblies, and thus the accuracy of determining the gaze position.
