8. A method, comprising:
- driving an array of first electrodes with a first drive signal, the first electrodes distributed across an active area of a touchscreen assembly such that the density of first electrodes increases in a first direction across the touchscreen;
driving an array of second electrodes with a second drive signal, the second electrodes distributed across an active area of the touchscreen assembly such that the density of second electrodes decreases in the first direction across the touchscreen; and
wherein the position in the first direction of an input on the touchscreen can be determined by the proportion of first and second density in the area of the input.

Abstract
A touchscreen display assembly has an array of first electrodes distributed across an active area of the touchscreen display assembly such that the density of first electrodes increases in a first direction across the touchscreen. An array of second electrodes is distributed across an active area of the touchscreen display assembly such that the density of second electrodes decreases in the first direction across the touchscreen. The position in the first direction of an input on the touchscreen can be determined by the proportion of first and second electrodes density in the area of the input.
