Abstract: This application provides an antenna, which is particularly used in a millimeter-wave radar or a broadband radar. A convex structure and a concave structure are formed on a side of a wide microstrip line in the antenna. A shape and a size of the convex structure and/or a shape and a size of the concave structure, a distance between convex structures, a distance between concave structures, and/or a distance between the convex structure and the concave structure are designed, to enable the convex structure and the concave structure to resonate at different frequencies. In this way, the convex structure and the concave structure support radiation of signals on different frequency bands, so that broadband radiation of the antenna is implemented.

Abstract: An electronic device includes 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 that is after a moment corresponding to the synchronization signal to enable the display control circuit to refresh to one row of at least one row on the display screen corresponding to the active optical component after a predetermined second delay that is after the active optical component completes light emission.

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.
