DRIVING METHOD OF FLAT SURFACE DISPLAY PANEL AND FLAT SURFACE DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a driving method of a flat surface display panel and a flat surface display capable of preventing generation of ghost and reverse transition by improving the fact that development of an OCB type liquid crystal display having high response speed and a wide visual field angle is proceeded instead of an TN type liquid crystal display and insufficient charge is generated in a blanking period and thereby a ghost and reverse transition of a white solid are generated even though black insertion for periodically applying high voltage is performed including the blanking period since driving voltage applied between a display pixel electrode and a counter electrode is made to be in a reverse transition state if a low voltage state is continued. SOLUTION: An intermediate gradation is set by providing a signal gradation setting means capable of setting gradation of the signal in the blanking period in a controller 13 controlling a gate driver 15 and a source driver 16 driving the flat surface display panel 17, or a black signal insertion period in the blanking period is set also in a part corresponding to a video signal writing period by a black signal insertion timing setting means 21 provided in the controller 13.
