CHARGE PUMP AND DISPLAY SYSTEM COMPRISING THE CHARGE PUMP

摘要

PURPOSE: A charge pump and a display system comprising the charge pump are provided to prevent an output voltage from suddenly dropping due to current consumption by increasing current supply capacity. CONSTITUTION: In a charge pump and a display system comprising the charge pump, a first conversion unit(210) generates a first pumping voltage. The first conversion unit outputs the first pumping voltage to first and second terminals alternately. A second conversion unit(220) generates a second pumping voltage. The second conversion unit supplies the second pumping voltage to the output terminal. The second pumping voltage is supplied to the output terminal during the half period of a second or a third clock.
