Abstract

A computer system includes a first display device to display an image and includes an application program to copy the image displayed on the first display device to a second display device. A selectable control, when selected, initiates that the application program copy the image displayed on the first display device to the second display device.

a housing top connected to the housing base, the housing top having at least a first side and a second side;

wherein the first display device is integrated into the first side of the housing top; and

wherein the second display device is integrated into the second side of the housing top such that the second display device is viewable when the housing top is positioned over the housing base.

8. A computer system as recited in claim 7, wherein the second display device is a non-volatile display configured to maintain the image for display without power applied.

9. A computer system as recited in claim 7, further comprising:

a memory component configured to maintain a second image; and

a second selectable control configured to initiate that the application program generate the second image for display on the second display device.

10. A computer system as recited in claim 9, wherein the second selectable control is accessible when the housing top is positioned over the housing base.

11. A computer system as recited in claim 1, wherein the selectable control is a push-button.

12. A computer system as recited in claim 1, wherein the selectable control is a programmed keyboard input.

13. A computer system as recited in claim 1, wherein the selectable control is rendered with the first display device as a selectable interface control.

14. A portable computing device, comprising:

a display device configured to display one or more images;

a non-volatile display device configured to display any of the one or more images, and further configured to maintain the one or more images for display without power applied; and

a selectable control configured to initiate that an image displayed on the display device be duplicated on the non-volatile display device.

15. A portable computing device as recited in claim 14, further comprising:

a housing base;

a housing top connected to the housing base, the housing top having at least a first side and a second side;

wherein the display device is integrated into the first side of the housing top; and

wherein the non-volatile display device is integrated into the second side of the housing top such that the non-volatile display device is viewable when the housing top is positioned over the housing base.

16. A portable computing device as recited in claim 15, further comprising:

a memory component configured to maintain image data corresponding to a second image;

a second selectable control configured to initiate that a second image be generated for display on the non-volatile display device; and

wherein the second selectable control is accessible when the housing top is positioned over the housing base.

17. A portable computing device as recited in claim 14, further comprising:

a memory component configured to maintain image data corresponding to a second image; and

a second selectable control configured to initiate that a second image be generated for display on the non-volatile display device.

18. A portable computing device as recited in claim 14, further comprising an application program configured to copy the image displayed on the display device to the non-volatile display device.

19. A portable computing device as recited in claim 18, wherein the application program is further configured to copy each bit of image data corresponding to the image displayed on the display device.

20. A portable computing device as recited in claim 18, further comprising a memory component configured to maintain image data, and wherein the application program is further configured to copy the image data corresponding to a second image displayed on the first display device to the memory component.

21. A portable computing device as recited in claim 18, further comprising:

a memory component configured to maintain image data, wherein the application program is further configured to copy the image data corresponding to a second image displayed on the first display device to the memory component; and

a second selectable control configured to initiate that the application program generate the second image for display on the non-volatile display device.

22. A portable computing device as recited in claim 14, wherein the selectable control is a push-button.

23. A portable computing device as recited in claim 14, wherein the selectable control is a programmed keyboard input.

24. A portable computing device as recited in claim 14, wherein the selectable control is rendered with the first display device as a selectable interface control.

25. A method, comprising:

receiving a selectable control input to initiate image copy to a second display device;

copying image data corresponding to the image displayed on a first display device; and

displaying the image on the second display device.

26. A method as recited in claim 25, wherein displaying includes maintaining the image for display on the second display device without power applied.

27. A method as recited in claim 25, wherein displaying includes maintaining the image for display on a non-volatile display device without power applied.

28. A method as recited in claim 25, wherein copying includes copying each bit of image data corresponding to the image displayed on the first display device.

29. A method as recited in claim 25, wherein copying includes reading each bit of image data corresponding to the image displayed on the first display device, and wherein displaying includes writing each bit of image data to the second display device.

30. A method as recited in claim 25, wherein copying includes acquiring the image data as it is communicated to the first display device for display on the second display device.
