Abstract:
1. A touch sensing apparatus, comprising: a plurality of pins; a logic control module generating a plurality of control signals having different control timings; at least one driving/sensing control module coupled with the logic control module and the pins, wherein the driving/sensing control module receives a first control signal of the control signals from the logic control module and controls the pins to execute a plurality of pin functions according to a first control timing of the first control signal, so that the pins simultaneously sense a plurality of analog data from a conductive thin film sensor; and at least one storage control module, wherein each storage control module comprises a plurality of storage capacitors, the at least one storage control module is coupled with the logic control module and the at least one driving/sensing control module and stores the analog data sensed by the pins in the storage capacitors according to a second control timing of a second control signal of the control signals; wherein a pin of the pins and a storage capacitor of the storage capacitors have a one-to-one corresponding relationship, so that the analog data sensed by the in is stored in a form of voltage in the corresponding storage capacitor; a buffer is disposed between the pin and the storage capacitor, a sensing switch is coupled with the pin and an input end of the buffer, a storage switch is coupled with an output end of the buffer and the storage capacitor, one end of a ground switch is coupled with the sensing switch and the input end of the buffer and the other end of the ground switch is grounded.
