Abstract

An example electronic display device comprises a flexible display panel, a support panel supporting the flexible display panel, a guide about which the support panel turns and an actuator to apply a local stimulus to selected portions of the support panel that are in proximity with the guide to facilitate changing the selected portions of the support panel from a rigid planar shape to a bent shape about the guide as the support panel and the display panel are moved about the guide and such that the support panel returns to the rigid planar shape once moved away from the guide.

First claim

What is claimed is:

1. An electronic display device comprising:
a flexible display panel;
a support panel supporting the flexible display panel;
a guide about which the support panel turns;
an actuator to apply a local stimulus to selected portions of the support panel that are in proximity with the guide to facilitate changing the selected portions of the support panel from a rigid planar shape to a bent shape about the guide as the support panel and the display panel are moved about the guide and such that the support panel returns to the rigid planar shape once moved away from the guide; and
a processor, wherein the support panel comprises an intermediate portion turning about the guide, a first portion on a first side of the intermediate portion and a second portion on a second side of the intermediate portion, the processor being sandwiched between the first portion and the second portion.

2. The electronic display device of claim 1 further comprising a housing, wherein the support panel comprises an intermediate portion turning about the guide, a first portion on a first side of the intermediate portion within the housing and a second portion on a second side of the intermediate portion projecting from the housing on an exterior of the housing.

3. The electronic display device of claim 2 , wherein a portion of the housing is transparent to facilitate viewing of the flexible display panel supported by the first portion within the housing.

4. The electronic display device of claim 2 , wherein the intermediate portion comprises a shape memory polymer to change to the bent shape about the guide in response to the stimulus comprising heat, light or electrical field.

5. The electronic display device of claim 1 further comprising a drive mechanism to drive the support panel and the flexible display panel about the guide.

6. The electronic display device of claim 1 , wherein the support panel comprises an open architecture, the open architecture having openings, each of the openings being individually completely surrounded by the support panel.

7. The electronic display device of claim 1 , wherein the support panel comprises a thermo-softening plastic to change to the bent shape about the guide in response to the stimulus comprising heat.

8. The electronic display device of claim 1 further comprising:
a second guide about which the support panel turns; and
a second actuator to apply a second stimulus to selected portions of the support panel that are in proximity with the second guide to facilitate changing the support panel from a rigid planar shape to a bent shape about the second guide as the support panel and the display panel are moved about the second guide and such that the support panel returns to the rigid planar shape once moved away from the second guide.

9. The electronic display device of claim 1 further comprising a housing, wherein the support panel comprises an intermediate portion turning about the guide, a first portion on a first side of the intermediate portion within the housing and a second portion on a second side of the intermediate portion, the housing having a transparent panel through which the flexible display panel supported by the first portion is viewable.

10. The electronic display device of claim 1 further comprising a retractor-extender to selectively move the support panel and the flexible display panel in at least one direction about the guide.

11. The electronic display device of claim 1 , wherein an entirety of those portions of the support panel moved away from the guide remain unbent.

12. The electronic display device of claim 1 , wherein the support panel when extending about the guide and when moved away from the guide has a single overall thickness between an uppermost surface and a lowermost surface of the support panel that remains constant.

13. The electronic display device of claim 1 , wherein the support panel comprises a light induced shape memory polymer.

14. The electronic display device of claim 1 further comprising:
at least one sensor to sense an extent at which at least one of the support panel or the display panel is moved away from the guide;
a processor to output control signals controlling presentation formatting of images on the flexible display panel based upon the sensed extent.

15. An electronic display device comprising:
a flexible display panel;
a support panel supporting the flexible display panel;
a guide about which the support panel turns;
an actuator to apply a local stimulus to selected portions of the support panel that are in proximity with the guide to facilitate changing the selected portions of the support panel from a rigid planar shape to a bent shape about the guide as the support panel and the display panel are moved about the guide and such that the support panel returns to the rigid planar shape once moved away from the guide;
a retractor extender to extend and retract the flexible display panel and the support panel; and
a processor to output control signals controlling extension and retraction of the flexible display panel by the retractor extender based upon a sensed sliding gesture across the flexible display panel.

16. An electronic display device comprising:
a flexible display panel;
a support panel supporting the flexible display panel;
a guide about which the support panel turns; and
an actuator to apply a local stimulus to selected portions of the support panel that are in proximity with the guide to facilitate changing the selected portions of the support panel from a rigid planar shape to a bent shape about the guide as the support panel and the display panel are moved about the guide and such that the support panel returns to the rigid planar shape once moved away from the guide;
a retractor extender to extend and retract the flexible display panel and the support panel;
a sensor to sense an orientation of the electronic display device; and
a processor to output control signals controlling extension and retraction of the flexible display panel by the retractor extender based upon the sensed orientation.

17. The electronic display device of claim 16 further comprising a housing, wherein the control signals that are based upon the sensed orientation move the flexible state panel between a first extended state in which the flexible display panel extends from the housing by a first usable length for viewing outside the housing and a second extended state in which the flexible display panel extends from the housing by second usable length for viewing outside the housing, the second usable length being different than the first usable length.

18. The electronic display device of claim 17 , wherein the sensed orientation comprises a direction at which the flexible display panel extends from the housing.
