摘要:
The present invention is related to a driving apparatus for a liquid crystal display, and a liquid crystal display including the same. A gate-on voltage generator includes first and second resistors connected between a predetermined reference voltage and a ground voltage, a voltage follower connected to a contact between the first resistor and the second resistor, a charge pump circuit connected to an output terminal of the voltage follower, and a gate-on voltage output terminal connected to the charge pump circuit. The voltage follower is disposed in front of the charge pump circuit such that an influence due to load changes is blocked to thereby prevent an excessive increase of the gate-on voltage during a blank time. Furthermore, two resistors having the same resistance are used to divide the reference voltage such that stress on the resistors may be minimized.
