To shorten a period necessary for a plurality of photosensors arranged in a display and data input region to receive light. In a first period, a reset operation is concurrently performed and then a storage operation is concurrently performed in a plurality of first photosensors while a plurality of first light-emitting elements emit light concurrently and a plurality of second light-emitting elements do not emit light. In a second period, the reset operation is concurrently performed and then the storage operation is concurrently performed in a plurality of second photosensors while the plurality of second light-emitting elements emit light concurrently and the plurality of first light-emitting elements do not emit light. In a third period, a selection operation is sequentially performed in the plurality of first photosensors and the selection operation is sequentially performed in the plurality of second photosensors.
