Abstract

A control system is provided for a touch panel with a plurality of sensing units. The control system includes a compensation circuit, a charge amplifier, and a signal processing circuit. The compensation circuit has a plurality of matching impendent networks. The compensation circuit receives a touch signal from a specific sensing unit among the plurality of sensing units and selects one of the plurality of matching impendent networks to serve as a transmission path of the touch signal for generating a compensated touch signal. The charge amplifier receives the compensated touch signal from the transmission path to generate an amplified touch signal. The signal processing circuit receives the amplified touch signal and detects whether the specific sensing unit is touched.
