Abstract
A touch sensing apparatus for accelerating a sensing signal processing operation is provided. The touch sensing apparatus includes a plurality of sets of horizontal sensing lines, a plurality of sets of vertical sensing lines, a plurality of processing circuits, and a plurality of sensing units. The plurality of sensing units output a plurality of sets of horizontal and vertical sensing signals via the plurality of sets of horizontal and vertical sensing lines respectively. Each processing circuit is coupled to corresponding sets of horizontal and vertical sensing lines. Furthermore, disclosed is a sensing signal processing method essentially including scanning the plurality of sets of horizontal sensing lines in synchronization for synchronously fetching the plurality of sets of horizontal sensing signals during a first interval, and scanning the plurality of sets of vertical sensing lines in synchronization for synchronously fetching the plurality of sets of vertical sensing signals during a second interval.
