Abstract
This disclosure provides systems, methods and apparatus implementations of a display device with a cover glass apparatus that serves as a single or multi-touch sensor, as a handwriting (or note capture) input device, and in some configurations as a fingerprint sensor. Sensor functionality and resolution can be tailored to specific locations on the cover glass apparatus. In some such implementations, the area in which the fingerprint sensing elements are located may provide not only fingerprint detection, but also handwriting and touch functionality. In some other implementations, the fingerprint sensor may be segregated into a separate, high-resolution zone that only provides fingerprint functionality.
