description An aspect of the disclosure provides a cover glass configured to overlie a display screen of a user equipment, UE, device, the cover glass comprising: a substrate arranged to overlie a said display screen for protecting said display screen, wherein the substrate has a display- facing surface and a user-facing surface; and a capacitive biometric skin contact sensor coupled to the substrate and configured to resolve the contours of skin proximal to the sensor, the sensor comprising: a plurality of gate drive channels; a plurality of read-out channels; a sensor array of sensor pixels, wherein each sensor pixel comprises a thin film transistor and an at least partially transparent capacitive sensing electrode coupled to the thin film transistor, and wherein each of the sensor pixels is coupled to both: (i) a gate drive channel to receive a scanning signal; and (ii) a read-out channel to provide a read-out signal; and conversion circuitry configured to process read-out signals received from sensor pixels to obtain biometric skin contact data therefrom; wherein the cover glass is arranged to couple to said UE device to enable transmission of biometric skin contact data from the conversion circuitry to a processor of said UE device.
