Electronic device and authentication method of electronic device
View Patent ↗An electronic device having an authentication method with high security is provided. The electronic device includes a pixel portion, a sensor portion, and an authentication portion. The pixel portion includes a display element and a light-receiving element. The pixel portion includes a first region and has a function of making the display element of the first region emit light. The pixel portion has a function of obtaining first authentication information by capturing an image of an object that is in contact with the first region with the use of the light-receiving element. The sensor portion includes a second region and has a function of obtaining second authentication information by capturing an image of an object that is in contact with the second region. The authentication portion has a function of performing first authentication processing using the first authentication information. The authentication portion has a function of performing second authentication processing using the second authentication information.
1 . An electronic device comprising:
a pixel portion comprising a first region;
a sensor portion comprising a second region; and
an authentication portion,
wherein the pixel portion comprises a light-emitting element, light-receiving element, and a light-blocking layer comprising openings at positions overlapping with the light-emitting element and the light-receiving element,
wherein the pixel portion is configured to light up the light-emitting element in the first region,
wherein the pixel portion is configured to capture an image of an object that touches the first region using the light-receiving element, and obtain a first authentication information,
wherein the first authentication information includes color information,
wherein the sensor portion is an ultrasonic sensor,
wherein the sensor portion is configured to capture an image of the object that touches the second region and obtain a second authentication information,
wherein the authentication portion is configured to both perform first authentication processing using the first authentication information and second authentication processing using the second authentication information, and
wherein the pixel portion and the sensor portion are provided on the same surface.
