Abstract
Signal processing for a touch and hover sensing display device is disclosed. A touch and hover sensing display device can include a sensing panel for sensing a touch or hover event, a display for displaying graphical information to select based on the touch or hover event, and a control system for processing a signal indicative of the touch or hover event. The control system can process the signal to determine to which display location a hovering object is pointing according to a profile of the object's shape. In addition or alternatively, the control system can process the signal to differentiate between a close small object and a distant large object so as to subsequently perform intended actions of the device based, at least in part, on the object distance and/or area (or size). The display can be positioned at a desirable distance from the panel so as to reduce interference from the display to the panel and avoid adverse effects on the signal.
