Abstract

In general, in one aspect, the disclosure describes an apparatus that includes two panels pivotally connected together. The panels can pivot from an open arrangement where the two panels lay side by side to a closed arrangement where the two panels lay one on top of another. The apparatus also includes a flexible display connected to the two panels and having a portion that is mechanically free from the two panels. The apparatus further includes a cavity to receive at least a portion of the free portion of the display when the panels are pivoted into the closed arrangement.

Claims

1. An apparatus comprising

panels pivotally connected together, wherein the panels can pivot from an open arrangement where the panels lay side by side to a closed arrangement where the panels lay one on top of another;

a flexible display connected to the panels and having a portion that is mechanically free from two panels, and

a cavity to receive at least a portion of the free portion of the display when the panels are pivoted into the closed arrangement.

2. The apparatus of claim 1, wherein the cavity is formed between the panels.

3. The apparatus of claim 1, further comprising a hinge connected to the panels.

4. The apparatus of claim 3, wherein the hinge provides electrical signals and power between the panels.

5. The apparatus of claim 3, wherein the display is connected to portions of the panels opposite the hinge and is free from portions of the panels having the hinge attached, and wherein the cavity is formed in the hinge and in the portions of the panels having the hinge attached.

6. The apparatus of claim 1, wherein the cavity is formed within one of the panels and the display enters the one panel when the panels are pivoted into the closed arrangement.

7. The apparatus of claim 6, wherein the cavity includes a roller for wrapping the display around when the display enters the cavity.

8. The apparatus of claim 7, wherein the one panel includes an expanded portion for housing the cavity and the roller.

9. The apparatus of claim 6, wherein the cavity is formed laterally along length of the one panel and includes rollers to laterally guide the display into the one panel.

10. The apparatus of claim 1, further comprising a tensioner to guide the free portion of display into the cavity.

11. The apparatus of claim 1, further including tabs to prevent the free portion of display from flexing out of the apparatus.

12. The apparatus of claim 1, wherein one of the panels provides only mechanical functions relating to protecting and opening the apparatus.

13. The apparatus of claim 1, wherein the panels are curved and the display is connected to opposite sides of the panels and is shorter than surface area of curved panels, and wherein the cavity is provided by space between the display and the curved panels.

14. The apparatus of claim 1, wherein the cavity enables the display to avoid being mechanically folded at a damagingly small radius of curvature when the panels are pivoted into the closed arrangement.

15. An electronic device comprising

panels pivotally connected together, wherein the panels can pivot from an open arrangement where the panels lay side by side to a closed arrangement where the panels lay one on top of another;

a flexible display connected to the panels and having a portion that is mechanically free from two panels,

a cavity to receive at least a portion of the free portion of the display when the panels are pivoted into the closed arrangement, wherein the cavity enables the display to avoid being mechanically folded at a damagingly small radius of curvature when the panels are pivoted into the closed arrangement;

a processor to control the electronic device; and

a battery to provide power to the device.

16. The device of claim 15, wherein the cavity is formed between the panels.

17. The device of claim 15, wherein the cavity is formed within one of the panels and includes a roller for wrapping the display around when the display enters the cavity.

18. The device of claim 15, wherein the cavity is formed within one of the panels and includes a roller to guide the display laterally along the one panel when the display enters the cavity.

19. The device of claim 15, further comprising a user interface.

20. The device of claim 15, further comprising an antenna to communicate.
