Method of driving liquid crystal display device

1. 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.

2. The method of claim 1 , wherein the data voltages displaying the image are supplied every N frames and the period comprises N frames.

3. The method of claim 2 , wherein the data voltages displaying the image alternate with an opposite polarity in every N frames.

4. The method of claim 3 , wherein N is an even number.

5. The method of claim 3 , wherein a first polarity pattern of the data voltages of first N frames is opposite to a second polarity pattern of the data voltages of next N frames.

6. The method of claim 5 , wherein each of the first and the second polarity patterns immediately follows a same polarity of the last frame in a preceding N frames, and afterwards followed by an alternating pattern of opposite polarities for the remaining N frames.

7. 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.

8. The method of claim 7 , wherein N is an even number.

9. The method of claim 7 , wherein a first polarity pattern of the first data voltages is opposite to a second polarity pattern of the second data voltages.

10. The method of claim 9 , wherein each of the first and the second polarity patterns are an alternating patterns in opposite polarities in at least every one frame.

11. 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 is of N number of frames and N is an even number;

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 displaying the image have opposite polarities for each of the periods of the N frames and having a last frame of the N frames displaying the image preceded by a remaining background frames, 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.

12. The method of claim 11 , wherein a first polarity pattern of the data voltages during first N frames is opposite to a second polarity pattern of the data voltages during next N frames.

13. The method of claim 12 , wherein each of the first and the second polarity patterns is an alternating patterns in opposite polarities in at least every one frame.
