Abstract
An optical fingerprint authentication device includes at least a light source and an image sensor and detects diffused light. The light source is an organic electroluminescence panel. The organic electroluminescence panel comprises a light emitting portion region and a light-transmitting non-light emitting portion, the light emitting portion region being shaped by an organic electroluminescence element. A fingerprint information reader having the image sensor arranged at a position adjacent to the non-light emitting portion is provided.
Claims13
An optical fingerprint authentication device which comprises at least a light source and an image sensor that detects diffused light from a finger surface side of the optical fingerprint authentication device and optically reads an entire fingerprint information of a specimen that is used to perform fingerprint authentication,
- wherein the light source is an organic electroluminescence panel,
- wherein the organic electroluminescence panel comprises a light emitting portion region and a light-transmitting non-light emitting portion, the light emitting portion region being shaped by an organic electroluminescence element, and
- wherein a fingerprint information reader having the image sensor arranged at a position adjacent to the non-light emitting portion is provided and an entire surface of the image sensor facing the finger surface side receives the diffused light.
