The OLED display has a front surface and a back surface. The computing device includes a moveable display support connected to the back surface of the display. In some implementations, the moveable display support is configured to limit bending in one direction to a first bend radius and to limit bending in another direction to a second bend radius. In some implementations, the moveable display support is formed by a plurality of unit cells. ## Claims ### Claim 1 A computing device, comprising: a flexible display including a thin film transistor matrix having a front surface and a back surface; and a moveable display support connected to the back surface of the display and configured to limit bending in one direction to a first bend radius while maintaining strain on the thin film transistor matrix below a predetermined amount of strain by elongating the moveable display support during bending. ### Claim 2 (depends on 1) The computing device of claim 1, wherein the moveable display support includes a plurality of interlocking elements. ### Claim 3 (depends on 1) The computing device of claim 1, wherein the moveable display support extends between a first edge of the flexible display and a second edge of the flexible display. ### Claim 4 (depends on 1) The computing device of claim 1, wherein the flexible display has a dimension from a first edge to a second edge and wherein the moveable display support extends from within five percent of the dimension of the first edge of the flexible display to within five percent of the dimension of the second edge of the flexible display. ### Claim 5 (depends on 1) The computing device of claim 1, wherein the moveable display support extends from a first edge of the flexible display to a second edge of the flexible display. ### Claim 6 (depends on 1) The computing device of claim 1, wherein the moveable display support is attached to the back surface of the flexible display. ### Claim 7 (depends on 1) The computing device of claim 1, wherein the flexible display includes a layer adjacent one or more front layers, and one or more back layers, to form a stack. ### Claim 8 (depends on 7) The computing device of claim 7, wherein the stack is foldable between infinite radius to a radius of 2 mm without additional support. ### Claim 9 (depends on 8) The computing device of claim 8, wherein the moveable display support and the flexible display cooperate to reduce the radius to which the stack is foldable by 1 mm. ### Claim 10 (depends on 1) The computing device of claim 1, wherein the moveable display support is formed of a material having sufficient hardness to prevent strain above 0.5% of the predetermined amount of strain. ### Claim 11 (depends on 1) The computing device of claim 1, wherein the moveable display support is formed by additive manufacturing. ### Claim 12 A computing device, comprising: a flexible display having a front surface and a back surface; and a moveable display support connected to the back surface of the display, the moveable display support formed by a plurality of unit cells. ### Claim 13 (depends on 12) The computing device of claim 12, wherein the moveable display support includes a second unit cell. ### Claim 14 (depends on 13) The computing device of claim 13, wherein the second unit cell is connected to the first unit cell. ### Claim 15 (depends on 12) The computing device of claim 12, the plurality of unit cells extends in rows and columns. ### Claim 16 (depends on 15) The computing device of claim 15, wherein a first row of unit cells of the plurality of unit cells and a second row of unit cells of the plurality of unit cells are interconnected. ### Claim 17 (depends on 15) The computing device of claim 15, wherein a first row of unit cells of the plurality of unit cells and a second row of unit cells of the plurality of unit cells are linked. ### Claim 18 (depends on 15) The computing device of claim 15, wherein a first row of unit cells of the plurality of unit cells and a second row of unit cells of the plurality of unit cells are pinned. ### Claim 19 (depends on 15) The computing device of claim 15, wherein a first row of unit cells of the plurality of unit cells and a second row of unit cells of the plurality of unit cells are directly connected. ### Claim 20 A computing device, comprising: an organic light-emitting diode (OLED) display including a thin film transistor matrix having a front surface and a back surface; and a moveable display support connected to the back surface of the display and configured to limit bending in one direction to a first bend radius and to limit bending in another direction to a second bend radius, the moveable display support formed by a plurality of unit cells, the moveable display support including a plurality of interlocking elements, wherein the OLED display has a dimension from a first edge to a second edge and wherein the moveable display support extends from within five percent of the dimension of the first edge of the OLED display to within five percent of the dimension of the second edge of the OLED display, wherein the moveable display support is attached to the back surface of the OLED display.
