The present invention relates to a driving circuit for a display panel, which comprises a pre-charge power supply, a pre-charge switch, a buffer circuit, and a plurality of resistive devices. Time-stamping devices may include correlator circuits in parallel with signal decoders to time-stamp communication sequences. By filling these through-holes with a conductive material, an X-direction-detection electrode is connected to the substrate while an Y-direction-detection electrode is connected to the substrate. The system has no need to use external hardware such as a dual-port Random Access Memory and a register, thus, the requirement of parameter transmission on the external hardware is reduced, and further the area and static power consumption of a chip are reduced. A bored rod is used as a housing member or a layered single outer wall.
