Abstract:
Disclosed is a liquid crystal display panel configured to include at least one common electrode bar and a plurality of divisional areas defined along a length direction of the at least one common electrode bar; a common voltage controller configured to divide a single frame into a plurality of intervals corresponding to the plurality of divisional areas and generate a common voltage control signal in each interval; and a common voltage compensator configured to generate a compensated common voltage on the basis of the common voltage control signal in each interval and apply the compensated common voltage to the at least one common electrode bar of the liquid crystal display panel.
