Flexible electronic devices
Flexible electronic devices may be provided. A flexible electronic device may include a flexible display, a flexible housing and one or more flexible internal components configured to allow the flexible electronic device to be deformed. Flexible displays may include flexible display layers, flexible touch-sensitive layers, and flexible display cover layers. The flexible housing may be a multi-stable flexible housing having one or more stable positions. The flexible housing may include a configurable support structure that, when engaged, provides a rigid support structure for the flexible housing. The flexible internal components may include flexible batteries, flexible printed circuits or other flexible components. A flexible battery may include flexible and rigid portions or may include a lubricious separator layer that provides flexibility for the flexible battery. A flexible printed circuit may include flexible and rigid portions or openings that allow some rigid portions to flex with respect to other rigid portions.
1. An electronic device, comprising:
a housing having first and second rigid portions joined by a flexible portion, wherein the first rigid portion is moveable relative to the second rigid portion;
a flexible display configured to flex with the housing;
at least one sensor that detects flexing of the flexible display; and
control circuitry that gathers sensor signals from the at least one sensor and performs user input functions based on the sensor signals.
2. The electronic device defined in claim 1 wherein the at least one sensor comprises first and second sensors and wherein flexing of the flexible display is detected based on a distance between the first and second sensors.
3. The electronic device defined in claim 2 wherein the control circuitry determines based on the sensor signals whether the distance between the first and second sensors is below a threshold.
4. The electronic device defined in claim 3 wherein the control circuitry turns off the flexible display when the distance between the first and second sensors is less than the threshold.
5. The electronic device defined in claim 3 wherein the control circuitry turns on the flexible display when the distance between the first and second sensors is greater than the threshold.
6. The electronic device defined in claim 1 wherein the at least one sensor comprises a light sensor.
7. The electronic device defined in claim 1 wherein the at least one sensor comprises a pressure sensor.
8. The electronic device defined in claim 1 wherein the at least one sensor comprises a capacitive sensor.
9. The electronic device defined in claim 1 wherein the at least one sensor comprises a switch and wherein the flexing of the flexible display activates the switch.
10. The electronic device defined in claim 9 wherein a portion of the housing contacts the switch when the flexible display is flexed to thereby activate the switch.
11. The electronic device defined in claim 9 wherein a portion of the flexible display contacts the switch when it is flexed to thereby activate the switch.
12. An electronic device, comprising:
a housing having a rigid portion and a flexible portion;
a flexible display;
at least one internal component that senses deformation of the flexible display; and
control circuitry that changes an operating mode of the electronic device in response to the deformation of the flexible display.
13. The electronic device defined in claim 12 wherein the flexible display comprises:
a flexible display layer; and
a flexible touch-sensitive layer.
14. The electronic device defined in claim 12 wherein the flexible portion of the housing comprises an elastomer.
15. The electronic device defined in claim 12 wherein the housing comprises a multi-stable housing having at least first and second stable positions.
16. A method for operating an electronic device having a flexible display and a housing, wherein the housing includes a rigid portion and a flexible portion, comprising:
with at least one sensor in the housing, receiving user input from a user by detecting deformation of the flexible display; and
with control circuitry in the housing, performing a user input function in response to sensor signals from the at least one sensor.
17. The method defined in claim 16 wherein the flexible display comprises an array of pixels and a touch sensor.
18. The method defined in claim 17 wherein performing the user input function in response to the sensor signals comprises changing display content that is displayed on the flexible display in response to the sensor signals.
19. The method defined in claim 16 wherein the at least one sensor comprises first and second sensors and wherein detecting the deformation of the flexible display comprises detecting a change in distance between the first and second sensors.
20. The method defined in claim 19 further comprising:
with the control circuitry, activating the flexible display when the distance between the first and second sensors is greater than a threshold; and
with the control circuitry deactivating the flexible display when the distance between the first and second sensors is less than the threshold.
