Abstract:
A driving process for a liquid crystal display in which a plurality of scanning lines and a plurality of signal lines are disposed in a grid arrangement, and display of an image corresponding with image data is performed by selecting any one of said scanning lines at one time, and altering a state of a liquid crystal via a signal line, the driving process comprising:setting a first scanning period and a second scanning period within a time frame for scanning any one of said scanning lines; displaying an image corresponding with said image data via said signal line during said first scanning period of said time frame on a first of said scanning lines; displaying a monochromatic image via said signal line during said second scanning period on a second of said scanning lines within said time frame, wherein said first and second scanning lines are separated by a predetermined number of scanning lines; and applying a varying voltage to a common electrode to allow the voltage of said signal line to be reduced, wherein the varying voltage is applied to the common electrode for one scanning period for displaying image data and another period for displaying a black image.
