1. An electronic device comprising:
a display panel having defined therein a display region comprising a first region, a second region adjacent to the first region, and a third region surrounding the first region and the second region, the display panel being configured to operate in a sensing mode, and comprising a first pixel in the first region, a second pixel in the second region, and a third pixel in the third region that comprise a pixel-driving circuit and a light-emitting element, and a first sensor in the first region, a second sensor, and a third sensor that comprise a sensor-driving circuit and a detection element, and
a readout circuit electrically connected to the first sensor, the second sensor, or the third sensor,
wherein, in the sensing mode, the first pixel is configured to emit first light with a first luminance, the second pixel is configured to emit second light with a second luminance that is different from the first luminance, the third pixel is configured to emit no light, and the readout circuit is configured to receive a readout signal from the first sensor.
