Abstract: Embodiments of this application disclose an electronic device, including a display screen, a display control circuit, an active optical component, and an optical control circuit. The active optical component is located below the display screen. The display control circuit is configured to control refreshing of the display screen, and output a synchronization signal to the optical control circuit. The optical control circuit is configured to receive the synchronization signal, and control the active optical component to start light emission after a predetermined first delay after a moment corresponding to the synchronization signal, so that after a predetermined second delay after the active optical component completes light emission, the display control circuit refreshes to one row of at least one row on the display screen corresponding to the active optical component.

Abstract: A smartwatch and, a method for controlling the smartwatch, where a plurality of capacitive touch sensors is disposed around a screen of the smartwatch. The method includes obtaining a calibrated capacitance value of each capacitive touch sensor, determining a quantity of touch points based on maximum values of calibrated capacitance values of the N capacitive touch sensors, where each touch point corresponds to one capacitive touch sensor, determining a location of each touch point based on a calibrated capacitance value of a capacitive touch sensor corresponding to the touch point and a calibrated capacitance value of a capacitive touch sensor neighboring to the capacitive touch sensor, and executing a control instruction matching the quantity of touch points and the location of each touch point.
