| titleOfInvention | Capacitive touch panel and capacitance sensing apparatus and method for the same |
| abstract | A capacitive touch panel and capacitance sensing apparatus and method for the same are disclosed. The capacitive touch panel includes a plurality of electrodes, a multiplexer and a capacitance sensing apparatus. The multiplexer selectively connects one of the electrodes to the capacitance sensing apparatus. The capacitance sensing apparatus includes a reference voltage source and a comparator, where the reference voltage source generates a modified reference voltage according to noise on stray capacitance of the capacitive touch panel. In a discharging process, the comparator compares an input voltage from the selected electrode and the modified reference voltage. The capacitance change in the electrode can be precisely detected because the noise is eliminated by differential comparison. |
