BRIGHTNESS AND POWER EFFICIENCY IN AUGMENTED REALITY (AR) DISPLAY DEVICES
This abstract first appeared for US patent application 20250104581 titled 'BRIGHTNESS AND POWER EFFICIENCY IN AUGMENTED REALITY (AR) DISPLAY DEVICES
Original Abstract Submitted
techniques for enhancing brightness and power efficiency in augmented reality (ar) display devices are described. to enhance brightness and power efficiency a near-eye display device's duty cycle may be adjusted based on a type of usage (e.g., world-locked or head-locked); a persistence or a display rate may be varied based on head movement speed; the brightness may be adjusted based on sensed ambient light; ambient brightness may be matched by utilizing camera-based scene understanding determining a user's gaze direction and then decreasing brightness of the gaze's peripheral; the display brightness may be controlled based on gaze and/or eye motion; and/or if the user is moving, world-locked rendering (wlr) targets and/or refresh rates may be altered, or wlr varied for peripheral content based on a comparison of gaze direction and a virtual object location.
