1. A display device with touch sensor input, comprising:
- a display layer; and
a touch sensor structure on top of the display layer, comprising a first and second array of electrodes, the electrodes in the first array being non-parallel to the electrodes in the second array,wherein the first array of electrodes occupies a first fraction of a touch sensor area, and the second array of electrodes occupies a different second fraction of the touch sensor area, wherein the arrays of electrodes each comprises straight electrode lines, with enlarged portions along the lines, with a spacing between the enlarged portions corresponding to the pitch between the electrode lines of other array, and wherein in reference to the touch area, the enlarged portions in one array have a different area and a same shape compared to the enlarged portions in the other array.

Abstract
A display device with touch sensor input has a touch sensor structure on top of the display layer. The touch sensor structure includes a first and second array of electrodes, the electrodes in the first array being non-parallel to the electrodes in the second array. The first and second arrays of electrodes occupy different fractions of a touch sensor area. These asymmetric fill factors give improved sensitivity.
