Zusammenfassung:An electronic device includes a pixel driving circuit to operate in a light emitting mode or a sensing mode and including a reference voltage line for receiving a reference voltage comprising a first reference voltage and a second reference voltage different from the first reference voltage and a light emitting diode including a first electrode, a light emitting element, and a second electrode. The light emitting diode has in an on-state or an off-state in the light emitting mode, the first reference voltage is applied to the reference voltage line in the light emitting mode, a first voltage is applied to the first electrode in the off-state, a second voltage is applied to the first electrode in the on-state, the sensing mode includes an initialization period and a sensing period, and the second reference voltage is applied to the reference voltage line in the initialization period.
