A device for driving an LCD panel comprises: a gray level voltage generation circuit, for generating gray level voltages, and determining whether the gray level voltages are generated by utilizing a first set of reference voltages or a second set of reference voltages according to a polarity inversion control signal, where the gray level voltage generation circuit determines whether a gray level voltage is generated by utilizing a maximum of the first set of reference voltages or a maximum of the second set of reference voltages, and determines whether another gray level voltage is generated by utilizing a minimum of the first set of reference voltages or a minimum of the second set of reference voltages; and a source driving circuit, for selecting a gray level voltage according to display data or inverted data of the display data to drive a source of a display cell of the LCD panel.
