摘要： A liquid crystal display according to the present invention can prevent interference fringe on a display panel due to a switching noise of a DC/DC converter, therefore a high-quality image can be displayed. Either of input signals for a timing control circuit is also supplied to a PLL circuit and the DC/DC converter is controlled by an output signal of the PLL circuit, thereby enables to synchronize a switching frequency of the DC/DC converter and control signal.
