1. A touch sensing control apparatus, comprising:
- a logic control module configured to generate a plurality of control signals, wherein each of the plurality of control signals has different control timing;
a driving sensing control module coupled to the logic control module comprising a parallel sensing control unit, wherein the driving sensing control module acts based on a driving sensing control signal of the logic control module;
a signal comparison module coupled to the logic control module and the driving sensing control module comprising at least one amplifier and a signal selecting unit, wherein the signal comparison module acts based on a signal comparison control signal;
a storage control module, coupled to the signal comparison module and the logic control module, wherein the storage control module acts based on a storage control signal of the logic control module;
a parallel timing control module, coupled to the logic control module and the storage control module, wherein the parallel timing control module acts based on a parallel timing control signal of the logic control module; and
an analog/digital converter, coupled to the logic control module and the parallel timing control module, wherein the analog/digital converter is configured to transmit a digital signal to the logic control module.
