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: Embodiments of the present disclosure provide an array substrate and method for manufacturing same, a display panel, and a display device, and relate to the field of display technologies. The array substrate includes a color filter layer, such that a distance between a light source on a side, distal from the color filter layer, of the base substrate and the color filter layer is less. Thus, light from regions of the color resist blocks is avoided being emitted from adjacent color resist blocks, and a cross color of the display panel is further avoided, such that the display effect of the display panel is great. In addition, the color resist block is at least partially overlapped with a second portion of a metal oxide pattern in an oxide thin film transistor, such that an overall footprint of the oxide thin film transistor and the color filter layer can be reduced, so as to acquire the display panel of high PPI.
