Abstract
Some touch screens can be formed with rows and columns of touch electrodes. In some examples, during a first time period, a first set of row electrodes are driven while a second set of row electrodes are sensed. In some examples, during a second time period, the first set of row electrodes are sensed while the second set of row electrodes are driven. In some examples, during a third time period, a first set of column electrodes are driven while a second set of column electrodes are sensed. In some examples, during a fourth time period, the first set of column electrodes are sensed while the second set of column electrodes are driven. In some examples, a touch image can be generated based on the data sensed from the first, second, third, and fourth time periods.
