摘要
A common voltage generation circuit includes a common voltage adjusting circuit adjusting a level of a common voltage in response to a compensation signal and providing the adjusted common voltage to a liquid crystal panel, and a common voltage compensating circuit including a resistor producing potential differences between the adjusted common voltage and each of the positive and negative polarity data voltages, a first voltage detector detecting a potential difference between the adjusted common voltage and the negative polarity data voltage, a second voltage detector detecting a potential difference between the adjusted common voltage and the positive polarity data voltage, and a voltage comparator comparing output signals of the first and second voltage detectors and feeding the compensation signal back to the common voltage adjusting circuit.
