Liquid crystal display with pre-writing and method for driving the same |
摘要 |
An object of the invention is to provide a method of driving a liquid crystal display in which optimum pre-writing can be performed on a first line during a vertical blanking line based on a data enable signal from a system. In a method of driving a liquid crystal display for controlling timing for outputting grayscale data to a predetermined pixel based on a data enable signal Enab, a period of the data enable signal is measured as a horizontal period (steps S<bold>2 </highlight>through S<bold>5</highlight>); a virtual enable signal is generated during a vertical blanking period based on the horizontal period (steps S<bold>6 </highlight>through S<bold>8</highlight>); the sum of the data enable signal and virtual enable signal is held as a vertical period (step S<bold>10</highlight>); and pre-writing of a predetermined grayscale data is performed at least in a pixel at a display starting line at a point in time that precedes the vertical period by an amount which is an integral multiple of the horizontal period (steps S<bold>11 </highlight>through S<bold>15</highlight>).
