Abstract: The present invention relates to a driving method for flat panel display devices, particularly a driving method combining a Multi Line Addressing (MLA) technique and a Frame Rate Control (FRC) technique, for flat panel display devices such as Liquid Crystal Display (LCD). In an embodiment the method of driving an image display device comprises the following steps: dividing row electrodes of an image device, having a plurality of row electrodes and a plurality of column electrodes, into a plurality of subgroups; selecting one of the plurality of said subgroups having a prefixed number of electrodes; performing a gray scale display by a frame rate control (FRC) by using a prefixed number of frames and a prefixed number of bits representing the gray levels; decomposing one of said frame in a number of time instants proportional to said prefixed number of electrodes; putting the bits representing the gray levels equally distributed in said prefixed number of frames.
