ABSTRACT:
A power control method for polarity inversion in an LCD panel comprises the step of providing a storage capacitor on a circuit board. Thereafter, the storage capacitor is charged to a first middle voltage. Next, the voltage of the VCOM channel is pulled up by a common output amplifier, only from the first middle voltage to a first upper voltage during a positive polarity period. Also, the voltage of the VCOM channel is pulled down by the common output amplifier, only from the first middle voltage to a first lower voltage during a negative polarity period.
