1. A functional panel comprising:
a first pixel; and
a second pixel,
wherein the first pixel comprises a first pixel circuit and a light-emitting element,
wherein the second pixel comprises a second pixel circuit and a photodiode,
wherein the first pixel circuit is configured to hold a first state on the basis of a control signal comprising a first level,
wherein in the first state, the light-emitting element does not perform light emission,
wherein the first pixel circuit is configured to hold a second state on the basis of a control signal comprising a second level,
wherein in the second state, the light-emitting element is configured to perform light emission,
wherein the first pixel circuit is configured to hold a third state on the basis of an image signal,
wherein in the third state, the light-emitting element is configured to perform light emission on the basis of the image signal,
wherein the second pixel circuit is configured to be initialized during a first period,
wherein the second pixel circuit is configured to obtain an imaging signal during a second period,
wherein the second pixel circuit is configured to supply the imaging signal during a third period,
wherein during the first period and the second period, the first pixel circuit is in the first state or the second state, and
wherein during the third period, the first pixel circuit is in the third state.
