ABSTRACT:
Provided is an apparatus for driving a display panel. The apparatus includes a main display control unit, an icon display control unit, a dot-matrix display control unit, first and second oscillators, an icon driver, and a dot-matrix driver. While the first oscillator generates a first clock signal composed of pulses having a first frequency and supplies the same to the dot-matrix display control unit, the second oscillator generates a second clock signal composed of pulses having a second frequency that is lower than the first frequency and supplies the second clock signal to the icon display control unit.
