CONTACT IDENTIFICATION AND TRACKING ON A CAPACITANCE SENSING ARRAY |
摘要 |
Active stylus operation when there is no physical connection between the stylus and the touch array requires communication and synchronization. It is possible to use the touchscreen stack-up itself to communicate synchronization signals or other information optically by outfitting the active stylus with an optical receiver and transmitting signals either with additional diodes or by modulating the display clock itself.
