Driving process for liquid crystal display
First Claim
1. 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.

Abstract
The provision of a liquid crystal display driving process which prevents the appearance of motion blur without any increase in circuit size or any reduction in panel numerical aperture. A driving process for a liquid crystal display in which a plurality of scanning lines 2 and a plurality of signal lines 3 are disposed in a grid like arrangement, and display of an image corresponding with image data is performed by selecting any one of the scanning lines 2 at one time, and altering the state of a liquid crystal via the signal line 3, wherein an image data selection period t1 and a black display selection period t2 are set within a time frame shorter than the time necessary for scanning any one of the aforementioned scanning lines 2, and an image corresponding with the aforementioned image data is displayed via the aforementioned signal line 3 during the image data selection period t1, and a monochromatic image is displayed via the aforementioned signal line 3 during the black display selection period t2.
