Abstract: A method for controlling a display screen according to an eye focus and a head-mounted electronic device are provided. The method is applicable to the head-mounted electronic device, the head-mounted electronic device includes a display screen, and the display screen is transparent when display is turned off. Furthermore, the method can include displaying an image on the display screen, an eye focus of a user being within a first distance range. The method can further include turning off the display screen, when it is detected that a duration in which the eye focus of the user is not within the first distance range is greater than or equal to a first duration. The method can lower power consumption, and reduce impact of an image on watching a real world.

Abstract: This application discloses a pair of glasses having a wireless charging receiver circuit, a glasses case for glasses, and a system, and relates to the field of terminal technologies. The glasses may automatically perform hardware reset without disposing a reset button. The glasses case includes a housing having a cavity configured to accommodate the glasses, a processor, and a wireless charging transmitter circuit coupled to the wireless charging receiver circuit. The processor is configured to determine that the glasses need to perform power-on reset; and the wireless charging transmitter circuit is configured to send a first signal to the glasses in response to a case in which the processor determines that the glasses need to perform power-on reset, to trigger at least one processor of the glasses to perform power-on reset.
