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.

Claims

1. 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.

2. The portable information device according to claim 1, wherein the biological information is a fingerprint.

3. The portable information device according to claim 1, wherein the biological information is a palm pattern.

4. The portable information device according to claim 1, wherein the sensor is incorporated in the display.

5. The portable information device according to claim 1, wherein the display is an organic EL display.

6. The portable information device according to claim 5,

wherein the organic EL display comprises a first substrate and a second substrate over the first substrate,

wherein a first sealing material is provided between the first substrate and the second substrate, and

wherein a second sealing material is provided outside the first sealing material.

7. The portable information device according to claim 1, further comprising an operating key, wherein the sensor works by pushing the operating key.

8. The portable information device according to claim 7, wherein the operating key is provided on a side of the portable information device.

9. The portable information device according to claim 1, further comprising a second circuit configured to select whether the sensor reads the biological information.

10. A portable information device comprising:

a display;

a sensor configured to read biological information of a user, the sensor comprising a plurality of pixels;

a first circuit configured to identify the user by checking the biological information; and

an antenna configured to transmit an identification information of the user,

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.

11. The portable information device according to claim 10, wherein the biological information is a fingerprint.

12. The portable information device according to claim 10, wherein the biological information is a palm pattern.

13. The portable information device according to claim 10, wherein the sensor is incorporated in the display.

14. The portable information device according to claim 10, wherein the display is an organic EL display.

15. The portable information device according to claim 14,

wherein the organic EL display comprises a first substrate and a second substrate over the first substrate,

wherein a first sealing material is provided between the first substrate and the second substrate, and

wherein a second sealing material is provided outside the first sealing material.

16. The portable information device according to claim 10, further comprising an operating key, wherein the sensor works by pushing the operating key.

17. The portable information device according to claim 16, wherein the operating key is provided on a side of the portable information device.

18. The portable information device according to claim 10, further comprising a second circuit configured to select whether the sensor reads the biological information.
