    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.

    Abstract: A device for identifying a pattern over a first surface includes a photosensitive layer, and a light-guiding layer disposed between the photosensitive layer and the first surface. The photosensitive layer includes a plurality of photosensitive elements, each configured to convert incident light into an electrical signal. The light-guiding layer includes a plurality of light-guiding units, each positionally corresponding to one of the plurality of photosensitive elements. Each light-guiding unit include a plurality of light-transmitting portions, each configured to guide a light beam reflected from a feature of the pattern positionally corresponding thereto to transmit therethrough and reach one of the plurality of photosensitive elements corresponding to the each of the plurality of light-guiding units. The device can be used for identification of fingerprint, as well as other biometric or non-biometric features, and has a reduced thickness and an improved accuracy for pattern identification.
