  • Embedded active matrix organic light emitting diode (AMOLED) fingerprint sensor
    Patent number: 9961178
    Abstract: Various embodiments provide a handheld computing device, such as a cellular phone, that includes a fingerprint sensor embedded in the device's display active area. The fingerprint sensor is composed of a series of PIN diodes that are configured to operate in a photo-receiving mode. In various embodiments, the PIN diodes are formed as active matrix organic light emitting diodes (AMOLEDs) at least partially within the gap between pixels in the display active area.
    Type: Grant
