Abstract:
A device includes a touch screen display comprising a touch sensitive panel and a display. The touch sensitive panel receives a touch event, and records the touch event as touch panel data. The device analyzes the touch panel data to identify the touch event as a valid or a non-valid touch event, determines, if the touch event is a non-valid touch event and based on the touch panel data, one or more regions of a touch panel display associated with the non-valid touch event, and turns off or dims the determined one or more regions of the touch panel display.
