Claim 6:
7. A method for operation of an electronic device comprising a control portion, a display portion, a memory portion, and a detection portion, comprising the steps of:
obtaining fingerprint data on a touching finger;
comparing the fingerprint data on the touching finger with fingerprint data on a plurality of fingers that is registered in advance; and
executing processing corresponding to fingerprint data that matches the fingerprint data on the touching finger among the fingerprint data on the plurality of fingers in the case where the fingerprint data on the touching finger matches any piece of the fingerprint data on the plurality of fingers,
wherein the detection portion is configured to detect a touch operation and to obtain fingerprint data of the touching finger,
wherein the display portion comprises a plurality of pixels,
wherein the plurality of pixels each include a light-emitting element and a light-receiving element,
wherein the light-emitting element and the light-receiving element are positioned on the same plane,
wherein the light-emitting element comprises a first electrode, a common layer, a light-emitting layer, and a common electrode,
wherein the first electrode, the common layer, the light-emitting layer, and the common electrode are stacked in the light-emitting element,
wherein the light-receiving element comprises a second electrode, the common layer, an active layer, and the common electrode,
wherein the second electrode, the common layer, the active layer, and the common electrode are stacked in the light-receiving element,
wherein the light-emitting layer and the active layer contain different organic compounds from each other,
wherein the first electrode and the second electrode are positioned on the same plane to be apart from each other,
wherein the common electrode covers the light-emitting layer and the active layer, and
wherein the common layer covers the first electrode and the second electrode.
