Abstract:
A fingerprint and proximity sensing apparatus for fingerprint recognizing and proximity sensing is provided. The fingerprint and proximity sensing apparatus includes a display panel, a fingerprint sensor, and at least one proximity sensing light emitting diode. The fingerprint sensor has an optical sensing array. The optical sensing array is configured to receive a first light emitted from the display panel and a second light emitted from the at least one proximity sensing light emitting diode at different time periods. The first light and the second light have different ranges of wave length. A sensing process is also provided.
