    摘要: 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.

    摘要: Disclosed are a near-eye display apparatus. The near-eye display apparatus comprises: a display screen; a polarization converter; an imaging lens group; a semi-transparent and semi-reflective layer arranged between the polarization converter and the first lens; a reflective polarized layer arranged on the side, facing away from the polarization converter, of the semi-transparent and semi-reflective layer, the polarization direction of the first linearly polarized light is vertical to the polarization direction of the second linearly polarized light; and a liquid crystal lens arranged between the semi-transparent and semi-reflective layer and the reflective polarized layer. When the liquid crystal lens is switched between the first phase retardation amount and the second phase retardation amount, the light path of light in the near-eye display apparatus changes, so that the near-eye display apparatus can image at two focal lengths.
