Liquid crystal display image presentation

1. A method to present an image on a display device, comprising:

receiving, in a graphics controller, an image comprising at least a first stationary portion and a second moving portion;

separating the first stationary portion from the second moving portion;

presenting the first stationary portion at a first refresh rate, where the first stationary portion has a first number of frames presented within a particular refresh period;

presenting the second moving portion at a second refresh rate, different from the first refresh rate, wherein the second moving portion has a second, larger number of frames presented within the particular refresh period;

generating at least two copies of the second moving portion; and

presenting a first copy of the second moving portion at a first location on the display device during a first refresh cycle and a second copy of the second moving portion at a second location on the display device during a second refresh cycle.

2. The method of claim 1 , wherein separating the first stationary portion from the second moving portion comprises analyzing, by a graphics controller, pixels in successive image frames received by the graphics controller to separate low-motion pixels from high-motion pixels, the method further comprising a framer producing, from the image, the first number of frames and the second number of frames.

3. The method of claim 1 , further comprising:

generating a third copy of the second moving portion; and

presenting the third copy of the second moving portion at a third location on the display device during a third refresh cycle.

4. The method of claim 3 , wherein:

the display device comprises a matrix of pixels;

different ones of first, second, and third copies of the second moving portion is shifted by a predetermined number of pixels during different ones of the first, second, and third refresh cycles.

5. The method of claim 4 , wherein the second refresh rate is multiple times greater than the first refresh rate.

6. The method of claim 1 , wherein the second number is multiple times the first number.

7. The method of claim 1 , wherein the first number is one, and the second number is three.

8. The method of claim 1 , wherein the first number of frames and the second number of frames contain data of the image.

9. The method of claim 1 , wherein the second number of frames includes the at least two copies.

10. A display device, comprising:

a liquid crystal module comprising a matrix of pixels;

a backlight assembly; and

a controller comprising logic to:

receive an image comprising at least a first stationary portion and a second moving portion;

separate the first stationary portion from the second moving portion;

present the first stationary portion at a first refresh rate;

present the second moving portion at a second refresh rate, larger than the first refresh rate, wherein the second refresh rate is multiple times the first refresh rate;

generate at least two copies of the second moving portion; and

present a first copy of the second moving portion at a first location on the display device during a first refresh cycle and a second copy of the second moving portion at a second location on the display device during a second refresh cycle.

11. The display device of claim 10 , wherein the controller further comprises logic to analyze pixels in successive image frames to separate low-motion pixels from high-motion pixels to identify the first stationary portion and the second moving portion.

12. The display device of claim 10 , wherein the controller further comprises logic to:

generate a third copy of the second moving portion; and

present the third copy of the second moving portion at a third location on the display device during a third refresh cycle.

13. The display device of claim 12 , wherein:

the controller further comprises logic to shift different ones of the first, second, and third copies of the second moving portion by a predetermined number of pixels during different ones of the first, second, and third refresh cycles.

14. The display device of claim 13 , wherein the second refresh rate is three times greater than the first refresh rate.

15. The display device of claim 10 , wherein the first stationary portion includes a first number of frames containing data of the image, and wherein the second moving portion includes a second, larger number of frames containing data of the image, the controller to present the first number of frames in a particular refresh period, and to present the second number of frames in the particular refresh period.

16. The display device of claim 15 , wherein the second number is an integer multiple of the first number.

17. A computing device, comprising:

a processor; and

a display device, comprising:

a liquid crystal module comprising a matrix of pixels;

a backlight assembly; and

a controller comprising logic to:

receive an image comprising at least a first stationary portion and a second moving portion;

separate the first stationary portion from the second moving portion;

present the first stationary portion at a first refresh rate, where the first stationary portion has a first number of frames to be presented within a particular refresh period;

present the second moving portion at a second refresh rate, different from the first refresh rate, wherein the second moving portion has a second, larger number of frames to be presented within the particular refresh period;

generate at least two copies of the second moving portion; and

present a first copy of the second moving portion at a first location on the display device during a first refresh cycle and a second copy of the second moving portion at a second location on the display device during a second refresh cycle.

18. The computing device of claim 17 , wherein the controller further comprises logic to analyze pixels in successive image frames received by the controller to separate low-motion pixels from high-motion pixels.

19. The computing device of claim 17 , wherein the controller further comprises logic to:

generate a third copy of the second moving portion; and

present the third copy of the second moving portion at a third location on the display device during a third refresh cycle.

20. The computing device of claim 19 , wherein:

the controller is to shift different ones of the first, second, and third copies of the second moving portion by a predetermined number of pixels during different ones of the first, second, and third refresh cycles.

21. The computing device of claim 20 , wherein the second refresh rate is three times greater than the first refresh rate.
