Abstract
An electronic device is provided. The electronic device includes a processor. The electronic device includes a display including a display driving circuit and a display panel. The electronic device includes a proximity sensor positioned below an active area of the display panel.
Claims20
An electronic device comprising:
- a display;
- and
- a proximity sensor for sensing an external object,
- wherein the proximity sensor includes:
- at least two light sources, positioned under an active area of the display, having different wavelengths, and
- at least one light-receiving circuitry configured to receive reflection light of the wavelengths, and
- wherein the at least two light sources are selectively driven in accordance with a state of the electronic device.
4 more elements
An electronic device comprising:
- at least one processor comprising processing circuitry;
- a display including display driver circuitry and a display panel;
- and
- a proximity sensor positioned under an active area of the display panel, wherein the proximity sensor is configured to:
- while a black color is provided through a portion of the active area over the proximity sensor, emit first light having a first wavelength to obtain data indicating whether an external object is adjacent to the display panel,
- wherein the first light is emitted while displaying an image on the display panel is deactivated, and is emitted while scanning of the display driver circuitry is ceased,
- obtain, from the display driver circuitry, a synchronization signal provided from the display driver circuitry to the at least one processor to indicate a timing for providing an image to the display driver circuitry, while the first light is emitted, and
- emit second light having a second wavelength longer than the first wavelength to obtain the data, in response to the synchronization signal.
