Abstract: An apparatus and a method of driving a touch panel that increases an analog-digital converting range includes a first resistive layer having first and second electrodes formed facing each other along opposing edges of the first resistive layer in a first direction, and a second resistive layer having third and fourth electrodes formed facing each other along opposing edges of the second resistive layer in a second direction. The apparatus also includes a high potential controller for selectively connecting one of the first and third electrodes to a high potential voltage supplied from a high potential voltage source and a low potential controller for selectively connecting one of the second and fourth electrodes to a low potential voltage. Further, a variable resistor is employed for reducing a voltage of the high potential voltage between the high potential controller and the high potential power voltage source.
