Abstract
A touch structure which is immune to variations in capacitance of a touch electrode to ground includes touch electrodestouch electrodes, auxiliary electrodes, and a driving circuit. The driving circuit drives the auxiliary electrodes with the same driving signal as the touch electrodes but does not read changes in capacitance of the auxiliary electrodes when determining touch events. A touch device using the touch structure and a method for driving the touch structure are also disclosed.
