Abstract
One embodiment provides a touch driving device for driving a touch panel that generates an auxiliary signal using a voltage source and a resistor, and generates a touch driving signal by combining the auxiliary signal and PWM driving pulses. Such touch driving device may change the voltage level of the voltage source or change the resistance value of the resistor to compensate for the characteristic deviation between channel circuits.
