ABSTRACT:
A method of stably driving a liquid crystal display apparatus and a liquid crystal display apparatus, the apparatus including a liquid crystal display panel having data electrode lines allocated for three colors and scan electrode lines crossing the data electrode lines and a lighting device installed in the back of the liquid crystal display panel to sequentially generate back lights having different colors, so that a unit driving period is divided into first, second, and third color driving periods. The liquid crystal display apparatus sequentially applies a single scan pulse to the scan electrode lines during a two-color driving period, in which the two color driving periods among the three color driving periods are combined, and activate two colors while the single scan pulse is applied to the scan electrode lines.
