Uniform signals from non-uniform patterns of electrodes

摘要

Apparatuses and methods of sense arrays with non-uniform patterns are described. One capacitive-sense array includes a first set of electrodes and a second set of electrodes. The first set of electrodes intersect the second set of electrodes to form a unit cells each corresponding to an intersection of a pair of electrodes comprising one electrode from the first set and one electrode from the second set. At one of the second set of electrodes includes a non-uniform conductive pattern including a first region being located at the intersection of the respective unit cell and a distal region being at a location within the respective unit cell that is farther away from the intersection than the first region. The first region includes a first conductive surface area and the distal region includes a second conductive surface area that is greater than the first conductive surface area.
