Abstract: A touch screen panel includes a plurality of sensing electrodes arranged in a touch active area, a charge pump circuit for generating an output voltage based on an input voltage and at least one clock signal, a clock signal generator for generating the clock signal, and a touch driver for generating touch driving signals by using the output voltage and applying the touch driving signals to the sensing electrodes. In the touch screen panel, the clock signal and the touch driving signals are synchronized with each other.
