1. A functional panel comprising:
a first driver circuit;
a second driver circuit; and
a pixel set,
wherein the first driver circuit is configured to supply a first selection signal and a second selection signal,
wherein the second driver circuit is configured to supply an image signal and a control signal,
wherein the control signal comprises a first level and a second level,
wherein the pixel set comprises a first pixel,
wherein the first pixel comprises a first element and a first pixel circuit,
wherein the first pixel circuit is supplied with the first selection signal, the second selection signal, the image signal, and the control signal,
wherein the first pixel circuit obtains the image signal on the basis of the first selection signal,
wherein the first pixel circuit obtains the control signal on the basis of the second selection signal,
wherein the first pixel circuit is configured to hold a first state to a third state,
wherein the first level is held in the first state,
wherein the second level is held in the second state,
wherein the image signal is held in the third state,
wherein the first element is electrically connected to the first pixel circuit,
wherein the first element performs display with first brightness on the basis of the first state,
wherein the first element performs display with second brightness on the basis of the second state,
wherein the first element performs display using the image signal on the basis of the third state, and
wherein the first brightness is darker than the second brightness.
