Abstract
A display is integrated with a touch screen and a fingerprint sensor having a plurality of substantially parallel drive lines configured to transmit a signal into a surface of a proximally located object and a plurality of substantially parallel pickup lines oriented proximate the drive lines and electrically separated from the pickup lines to form intrinsic electrode pairs that are impedance sensitive at each of the drive and pickup proximal locations. The display may comprise an OLED display with an OLED injector layer and an OLED emissive layer disposed between the drive lines and pickup lines.
