Abstract
Systems, methods and apparatuses may provide for a flexible display assembly including a flexible display and a backplane coupled to the flexible display, wherein at least a portion of the backplane comprises a super elastic sheet. In one example, the backplane includes a first rigid sheet metal portion and a second rigid sheet metal portion, wherein the super-elastic sheet is joined between the first and second rigid sheet metal portions.
Claims27
A portable processing device, comprising:
- a device body having a front surface, a back surface, a first end of the device body along aligned respective first sides of the front and back surfaces of the device body, and a second end of the device body opposite to the first end of the device body along aligned respective second sides of the front and back surfaces;
- a flexible display coupled to the front surface of the device body at an inner portion of the flexible display, wherein a first outer portion of the flexible display extends beyond the first end of the device body, wherein a second outer portion of the flexible display extends beyond the second end of the device body, a first bend portion of the flexible display is positioned between the inner portion of the flexible display and the first outer portion of the flexible display, and wherein a second bend portion of the flexible display is positioned between the inner portion of the flexible display and the second outer portion of the flexible display;
- a first hinge coupled to the device body proximate to the first end of the device body to support the first outer portion of the flexible display, the first hinge comprising:
- a first cylinder to provide a first bend radius which is greater than or equal to a minimum bend radius of the flexible display;
- and
- a first rigid sheet coupled to the first cylinder to support the flexible display in at least a portion of the first outer portion of the flexible display;
- a second hinge coupled to the device body proximate to the second end of the device body to support the second outer portion of the flexible display, the second hinge comprising:
- a second cylinder to provide a second bend radius which is greater than or equal to the minimum bend radius of the flexible display;
- and
- a second rigid sheet coupled to the second cylinder to support the flexible display in at least a portion of the second outer portion of the flexible display;
- a first super-elastic sheet positioned to support the flexible display at least in a first region corresponding to the first bend portion of the flexible display;
- and
- a second super-elastic sheet positioned to support the flexible display at least in a second region corresponding to the second bend portion of the flexible display.

A portable processing device, comprising:
- a device body having a front surface, a back surface, and an end surface along aligned respective first sides of the front and back surfaces of the device body;
- a flexible display coupled to the front surface of the device body at an inner portion of the flexible display, wherein an outer portion of the flexible display extends beyond the end surface of the device body, and a bend portion of the flexible display is positioned between the inner portion of the flexible display and the outer portion of the flexible display;
- a hinge coupled to the device body proximate to the end surface to support the outer portion of the flexible display through a range of motion from a first position wherein the outer portion of the flexible display is substantially coplanar with the inner portion of the flexible display and a second position wherein the outer portion of the flexible display is folded around the end surface of the device body, the hinge comprising:
- a cylinder to provide a bend radius that is greater than or equal to a minimum bend radius of the flexible display, and
- a rigid sheet coupled to the cylinder to support the flexible display in at least a portion of the outer portion of the flexible display;
- and
- a super-elastic sheet positioned to support the flexible display at least in a first region corresponding to the bend portion of the flexible display.
