Abstract
A method of driving a liquid crystal display device includes supplying data voltages to a pixel on a moving path of an image during a scroll operation, wherein the data voltages displaying the image have opposite polarities.
Claims13
A method of driving a liquid crystal display device, the method comprising:
- receiving a moving speed of an image which is moved by a scroll operation along a path over a background;
- determining a period of displaying the image based on the moving speed of the image moved by the scroll operation, wherein the period comprises an even number of frames having a last frame displaying the image preceded by a remaining background frames;
- supplying data voltages to a pixel of the image which is moved by the scroll operation along the path over the background, wherein the data voltages of the pixel exhibit periodic opposite polarities based on the period when displaying the image;
- and
- wherein the liquid crystal display device includes a timing controller supplied with an information from an external system for detecting a moving speed of the scroll operation expressed in M pixel/frame by detecting movement of the image on the background, wherein M is an even number,
- wherein the external system is for supplying control signals including a vertical synchronization signal, a horizontal synchronization signal, a data enable signal and a data clock signal to the timing controller.

A method of driving a liquid crystal display device, the method comprising:
- receiving a moving speed of an image which is moved by a scroll operation along a path over a background;
- determining a period of displaying the image based on the moving speed of the image moved by the scroll operation, wherein the period comprises N number of frames and wherein N is an even number;
- supplying first data voltages to a pixel of the image which is moved along the path over the background during a first period of N frames of a scroll operation determined based on the moving speed;
- and
- supplying second data voltages to the pixel during a next period of N frames of the scroll operation determined based on the moving speed,
- wherein a first data voltage of a last frame of the first period of N frames and a second data voltage of a last frame of the next period of N frames display the image and have opposite polarities, and
- wherein the liquid crystal display device includes a timing controller supplied with an information from an external system for detecting the moving speed of the scroll operation expressed in M pixel/frame by detecting movement of the image on the background, wherein M is an even number,
- wherein the external system is for supplying control signals including a vertical synchronization signal, a horizontal synchronization signal, a data enable signal and a data clock signal to the timing controller.
