Liquid crystal panel drive and method of driving liquid crystal panel

A method of driving a plurality of pixels in a liquid crystal panel according to an input image signal, said method improving a hysteresis of the liquid crystal panel and comprising the steps of:

• storing a frame memory signal including:
• (1) a reference peak level corresponding to a hysteresis generation level,
• (2) a duration of time that a peak level of the input image signal has equaled the stored reference peak level, and
• (3) a duration of time that an intermediary level of the input image signal, which is less than the stored reference peak level, has persisted;
• sequentially revising said frame memory signal on the basis of a present level of the input image signal;
• and
• driving the liquid crystal panel by a drive signal determined on the basis of a voltage brightness correction characteristic of the liquid crystal panel selected according to both the revised frame memory signal, and the present level of the input image signal,
• wherein the liquid crystal panel is driven by the drive signal in said driving step so as to be capable of producing for each of the plurality of pixels, a multi-level display.
