A bendable device is provided. The device comprises: a display stack which comprises a window layer and at least one active layer, and a body which comprises an extendable bending region. The active layers are fixed to the window layer at the bottom side of the window layer. Edges of the window layer extend outwards in relation to the at least one active layer at two or more sides of the display stack, and the window layer is rigidly fixed to the body at the edges which extend outwards at the bottom side of the window layer. A method for assembling a bendable device comprising a display is disclosed.

1. A bendable device comprising: a display stack comprising a window layer and at least one active layer, anda body positioned under the display stack and comprising a casing, the body that includes an extendable bending region configured for extending in one direction and bending in another directi
1. A bendable device comprising: a display stack comprising a window layer and at least one active layer, anda body positioned under the display stack and comprising a casing, the body that includes an extendable bending region configured for extending in one direction and bending in another direction along a single axis to allow the display stack to bend,wherein: the at least one active layer is fixed to the window layer at a bottom side of the window layer,edges of the window layer extend outwards in relation to the at least one active layer at two or more sides of the display stack,the window layer is fixed to the body at edges, wherein the body extends outward,the casing encloses the body, the at least one active layer, and the bottom side of the window layer,the extendable bending region comprises a different material than the casing. 2. The device of claim 1, wherein the at least one active layer is one of a plurality of layers of the display stack that are fixed to each other by an optically clear adhesive. 3. The device of claim 1, further comprising a space filled with nonadhesive material between the at least one active layer of the display stack and the body. 4. The device of claim 1, wherein: the at least one active layer is separated from the body by a space, and said space is filled with nonadhesive material. 5. The device of claim 1, wherein the extendable bending region of the body is a hinge. 6. The device of claim 1, wherein the extendable bending region of the body is an elastic component. 7. The device of claim 1, operable in at least two states including: a first state in which the display stack and the body are substantially flat, and the extendable bending region of the body is unextended,a second state in which the display stack and the body are bent,wherein in the bent state the inner bending curvature of the device is on the top side of the window layer. 8. The device of claim 7, wherein the device is bendable about at least one axis which lies in a same plane as the window layer in the first state of the device. 9. The device of claim 8, wherein the display stack and the body are bendable at least 20 degrees. 10. The device of claim 1, wherein the display stack and the body are bendable more than 90 degrees. 11. The device of claim 1, wherein the display stack comprises an active display layer and an active touch sensing layer. 12. The device of claim 11, wherein the active display layer comprises a flexible organic light-emitting diode display. 13. The device of claim 11, wherein the display stack further comprises a polarizing layer. 14. The device of claim 1, wherein the window layer comprises a viscoelastic material selected from the group of: polyethylene terephthalate and polyimide. 15. The device of claim 1, wherein the window layer is fixed to the body by an adhesive selected from the group of: pressure sensitive adhesive, epoxy, and ultraviolet cured adhesive. 16. The device of claim 1 implemented as a portable electronic device. 17. A bendable electronic device, comprising: a display stack comprising a window layer and at least one active layer, anda body positioned under the display stack and comprising a casing, the body with an extendable bending region configured for extending in one direction and folding in another direction along a single axis to allow the display stack to bend,wherein: the at least one active layer is fixed to the window layer at a bottom side of the window layer,edges of the window layer extend outwards in relation to the at least one active layer at two or more sides of the display stack,the window layer is fixed to the body at peripheral edges, wherein the body extends outward,the casing encloses the body, the at least one active layer, and the bottom side of the window layer,the extendable bending region comprises a different material than the casing. 18. A bendable electronic device, comprising: a display stack comprising a window layer and at least one active layer, anda body positioned under the display stack and comprising a casing, the body with an extendable bending region configured for extending in one direction and folding in another direction along a single axis to allow the display stack to bend,wherein: the at least one active layer is fixed to the window layer at a bottom side of the window layer,edges of the window layer extend outwards in relation to the at least one active layer at two or more sides of the display stack,the window layer is fixed to the body at peripheral edges, wherein the body extends outward,the casing encloses the body, the at least one active layer, and the bottom side of the window layer,the extendable bending region comprises a different material than the casing. 19. The bendable electronic device of claim 18, further comprising a space filled with nonadhesive material between the at least one active layer of the display stack and the body. 20. The bendable electronic device of claim 18, wherein the display stack further comprises a polarizing layer.
