Abstract
A touch sensing circuit and method is provided. The touch sensing circuit discriminates a common voltage change of a display panel couple to the touch sensor in a touch panel display apparatus. The touch sensor comprises a plurality of sensor electrodes. The touch sensing circuit includes a plurality of channel circuits, each of which includes a reset switch and a sensing switch for alternately conducting an associated sensor electrode to a reset voltage and a charge collecting circuit. The channel circuits are divided to different groups that operate according to interleaving timings for encompassing possible common voltage changes.
