Abstract
Disclosed is a touch screen and a method of touch screen having 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. The individual output of the multiplexed sensor segments subsections can be either combined into a single signal for processing during a normal scan, or their individual output can be processed individually for higher resolution. Using two scans, the first a normal scan, and the second a higher resolution scan, the disclosed touch screen and methods zoom in on the proximity of the touched area and scans with a higher resolution the proximity only where it is needed.
