Discriminative controller and driving method for touch panel with array electrodes
A touch panel device includes a two dimensional array of electrodes comprising a plurality of electrodes, and a controller electrically coupled to the two dimensional array of electrodes. A first portion of the electrodes are assignable by the controller as drive electrodes or unused electrodes, and...

| description | A touch panel device includes a two dimensional array of electrodes comprising a plurality of electrodes, and a controller electrically coupled to the two dimensional array of electrodes. A first portion of the electrodes are assignable by the controller as drive electrodes or unused electrodes, and a second portion of the electrodes are assignable by the controller as sense electrodes or unused electrodes. The controller is configured to: assign drive electrodes and sense electrodes during a plurality of measurement periods, wherein a pattern of assigned drive electrodes and sense electrodes is different during different measurement periods, and form mutual capacitances over a plurality of coupling distances during the plurality of measurement periods; measure mutual capacitances formed between the drive electrodes and the sense electrodes during the measurement periods; and detect and determine a position of an object that is touching or in close proximity to the touch panel device based on the measured mut |
