Abstract
An apparatus and method are provided to rapidly and accurately measure the variation of capacitance in a panel load of a touch sensor and thus increase touch sensitivity and noise resistance. The apparatus includes a panel driver configured to drive a panel load in the touch sensor according to a reference voltage, and a capacitive load detector configured to measure capacitance of the panel load by sensing a panel load driving current that is applied to the panel load by the panel driver.
