Claim:
1. A method of controlling a touch panel including a plurality of drive lines, a plurality of orthogonal sense lines, and a plurality of sensors, the method comprising: simultaneously applying a drive signal to each of a group of drive lines of the touch panel, each of the drive signals being applied to a corresponding drive line in the group during a time slot and all the applied drive signals having the same electrical characteristics over the time slot; sensing over multiple time slots sense signals generated on the sense lines in response to the applied drive signals, the applied drive signals having the same electrical characteristics over all the multiple time slots; processing only the sense signals generated during the multiple time slots to detect touches of the touch panel; applying a drive signal to a first drive line during a first time slot; and applying a drive signal to a last drive line during a last time slot, wherein the first and last time slots are twice as long as the time slots between the first and last time slots.
