A position sensing display integrates a touch sensor with an active matrix LCD panel. X sense electrodes and y sense electrodes in respective layers on a front panel are coupled capacitatively to respective sense circuits on active rear panel. A common electrode is driven, and the resulting signal on the x-sense electrodes and y sense electrodes is measured by the respective sense circuits. Changes in the resulting signal when sensed object approaches are measured to locate the sensed object. |
