1. A touch display device, comprising:
- a substrate;
a plurality of sub-pixels disposed on the substrate; and
a first sense electrode disposed on the substrate, wherein the first sense electrode is corresponding to the plurality of sub-pixels, and the first sense electrode comprises;
a first sub-electrode extended along a first direction;
a second sub-electrode extended along the first direction and adjacent to the first sub-electrode; and
a third sub-electrode extended along the first direction and adjacent to the second sub-electrode,wherein the first sub-electrode, the second sub-electrode, and the third sub-electrode are directly connected, the second sub-electrode is disposed between the first sub-electrode and the third sub-electrode, there is no sub-electrode located between the first sub-electrode and the second sub-electrode, and there is no sub-electrode located between the second sub-electrode and the third sub-electrode,wherein a pitch between the first sub-electrode and the second sub-electrode in a second direction perpendicular to the first direction is defined as a first pitch, a pitch between the second sub-electrode and the third sub-electrode in the second direction is defined as a second pitch, and the second pitch is greater than the first pitch.

Abstract
A touch sensor input device includes a first and second array of electrodes, the electrodes in the first array being orthogonal to the electrodes in the second array. A capacitor sensing arrangement senses an electrode capacitance signal which varies in the presence of a touch input. The capacitance signals for groups of electrodes in each array are combined in order to derive respective individual sense signals. This arrangement has electrodes with a finer resolution than the sensing resolution, and this gives improved ability to sense accurately the position of the touch input.
