Abstract:
1. A touch screen, comprising: a first plurality of sensor segments coupled to first scan lines; and a second plurality of sensor segments being subsections of one of the first plurality of sensor segments, the second plurality of sensor segments including second scan lines that are bundled by a multiplexer configured to aggregate output of the second plurality of sensor segments into a single transmission channel of a first scan line, wherein the multiplexer is configured to process signals of the second scan lines individually; wherein the first scan lines and the second scan lines are configured to be in communication with a controller; wherein the controller is configured to drive a scan of the first scan lines to determine receipt of an input to one of the first plurality of sensor segments; wherein the controller is configured to drive a scan of the second scan lines individually when input to the one of the first plurality of sensor segments is determined; and wherein the controller is in communication with a memory configured to store a plurality of applications, wherein the controller is configured to selectively drive scans of the second scan lines depending upon which of the plurality of applications is processed by the controller.
