Patent ID: 8643580

Claim:
A method for driving a liquid crystal display device, comprising the steps of: supplying first image signals to pixels in first to n-th rows through first data lines sequentially and supplying second image signals to pixels in (n+1)-th to 2n-th rows through second data lines sequentially during a first period; supplying a part of third image signals corresponding to the pixels in the first row to the first data lines and supplying a part of fourth image signals corresponding to the pixels in the (n+1)-th row to the second data lines while deselecting the pixels in the first to 2n-th rows during a second period; supplying the third image signals to the pixels in the first to n-th rows through the first data lines sequentially and supplying the fourth image signals to the pixels in the (n+1)-th to 2n-th rows through the second data lines sequentially during a third period; lighting first light sources with a first color in a backlight during the step of supplying the first image signals; and lighting second light sources with a second color in the backlight during the step of supplying the second image signals, wherein the supplying the first image signals and the supplying the second image signals during the first period are performed concurrently, wherein the supplying the third image signals and the supplying the fourth image signals during the third period are performed concurrently, wherein the first image signals and the second image signals are positive voltages, wherein the third image signals and the fourth image signals are negative voltages, wherein the second period is between the first period and the third period, wherein the first image signals are signals corresponding to the first color, wherein the second image signals are signals corresponding to the second color, wherein n is a natural number of 2 or more, and wherein each of the first data lines and each of the second data lines correspond to one column of pixels.
