The present application provides a display apparatus and a control method therefor. The display apparatus includes a mainboard, a power board, and a display panel, where the mainboard acquires a refresh rate of to-be-displayed video data, and adjusts a backlight control signal according to the refresh rate; and the power board drives a backlight source of the display panel according to the received backlight control signal.

Systems, methods, and non-transitory computer readable media including instructions for selectively controlling display of digital objects are disclosed. Selectively controlling display of digital objects includes generating a plurality of digital objects for display in connection with use of a computing device operable in a first display mode wherein the plurality of digital objects are displayed via a physical display and in a second display mode wherein some of the plurality of digital objects are displayed via the physical display, and at least one other of the plurality of digital objects is displayed via a wearable extended reality appliance; determining a usage status of the wearable extended reality appliance; selecting a display mode based on the usage status of the wearable extended reality appliance; and in response to the display mode selection, outputting for presentation the plurality of digital objects in a manner consistent with the selected display mode.

Methods, systems, apparatuses, and computer-readable media are provided for enabling collaboration between physical writers and virtual writers. In one implementation, the computer-readable medium includes instructions to cause a processor to receive, from an image sensor, image data representing a hand of a first physical writer holding a physical marking implement and engaging with a physical surface to create tangible markings. Information based on the image data is transmitted to a computing device associated with a second virtual writer, to thereby enable the second virtual writer to view the tangible markings created by the first physical writer. Annotation data are received from the computing device, and represent additional markings in relative locations with respect to the tangible markings created by the first physical writer. In response to receiving the annotation data, a wearable extended reality appliance overlays the physical surface with virtual markings in the relative locations.

Systems, methods, and non-transitory computer readable media including instructions for performing duty cycle control operations for a wearable extended reality appliance are disclosed. Performing the duty cycle control operations includes receiving data representing virtual content in an extended reality environment associated with a wearable extended reality appliance; identifying in the extended reality environment a first display region and a second display region separated from the first display region; determining a first duty cycle configuration for the first display region; determining a second duty cycle configuration for the second display region, wherein the second duty cycle configuration differs from the first duty cycle configuration; and causing the wearable extended reality appliance to display the virtual content in accordance with the determined first duty cycle configuration for the first display region and the determined second duty cycle configuration for the second display region.
