Abstract
A touch sensing apparatus is disclosed. The touch sensing apparatus includes a logic control module, at least one storage control module, and at least one decoding control module. The logic control module is used to generate a plurality of control signals having different control timings. The plurality of control signals includes a storage control signal and a decoding control signal. Each storage control module includes a plurality of storage capacitors, and respectively stores each of sensed voltages in different storage capacitors at different times according to a storage control timing of the storage control signal. The sensed voltages are analog data sensed from scan lines of an ITO sensor. The decoding control module performs analog adding process to the sensed voltages stored in the storage capacitors according to a decoding control timing of the decoding control signal to output decoded analog data with high signal-to-noise ratio (SNR).
