Abstract
The present invention provides a system for identifying an individual provided with a portable communication device. In a system for identifying an individual using a portable communication device with a display, the display is a sensor-incorporated display, the sensor-incorporated display reads the biological information of a user, and, based on the read information, identifies an individual.
Claims18
A portable information device comprising:
- a display;
- a sensor configured to read biological information of a user, the sensor comprising a plurality of pixels;
- and
- a first circuit configured to identify the user by checking the biological information,
- wherein each of the plurality of pixels comprises a semiconductor layer and a metal layer over the semiconductor layer,
- wherein the semiconductor layer includes a first impurity region and a second impurity region,
- wherein a first edge of the metal layer is aligned with an edge of the first impurity region, and
- wherein a second edge of the metal layer is aligned with an edge of the second impurity region.
