Patent ID: 8743082

Claim:
An apparatus, comprising: a substantially transparent substrate; a handwriting and touch sensor formed in a first zone of the substantially transparent substrate, the handwriting and touch sensor including a first plurality of substantially transparent electrodes; a fingerprint sensor formed in a second zone of the substantially transparent substrate, the fingerprint sensor including a second plurality of substantially transparent electrodes; and a control system configured for communication with the first plurality of substantially transparent electrodes and the second plurality of substantially transparent electrodes, the control system being further configured for controlling the apparatus to function as the touch sensor, the handwriting sensor, and the fingerprint sensor, wherein the control system is configured to control the apparatus to function as the touch sensor according to changes in capacitance received via the first plurality of substantially transparent electrodes, wherein the control system is configured to control the apparatus to function as the fingerprint sensor according to changes in resistance received via the second plurality of substantially transparent electrodes and wherein at least part of the control system is configured to be switchable from a touch mode configuration to a handwriting mode configuration.
