Patent ID: 7893901

Claim:
An apparatus for driving a hold-type display panel, the apparatus comprising: an LCD (liquid crystal display) panel comprising a plurality of gate lines and a plurality of intersecting data lines forming a matrix of pixels displaying an image corresponding to data signals applied to the data lines according to gate pulses applied to the gate lines; a signal controlling unit generating a gate control signal for selecting the gate lines and image data to be displayed on the LCD panel and generating predetermined dummy data during a dummy data display interval set within a blank interval of a vertical synchronization signal; a gate driving unit applying selected gate pulses to the gate lines; and a data driving unit generating the data signals corresponding to the image and applying the data signals to corresponding data lines, wherein the signal controlling unit shifts the selected gate line by a predetermined number of gate lines to a shifted gate line when a frame is changed when it is determined that a location of an area currently being scanned has entered an effective data display interval and the gate driving unit subsequently applies the selected gate pulses to the shifted gate line rather than to the originally selected gate line, and when the shift of the predetermined number of gate lines is such that the selected gate line is shifted past a final gate line, shifting is continued from a first gate line.
