摘要：
An apparatus includes a polarity reversing section which generates a polarity reversing signal for the liquid crystal drive voltage; a liquid crystal driver which reverses the polarity of the liquid crystal drive voltage based on the polarity reversing signal to drive the liquid crystal display panel; a warning signal generation section which generates a warning signal indicating the polarity reverse before the polarity of the liquid crystal drive voltage is reversed; and a regulator section which controls a supply of the liquid crystal drive voltage in accordance with the warning signal.
