Definitions
- the present invention generally relates to flexible displays.
- the present invention specifically relates to an efficient incorporation of a flexible display into a wrap display system.
- Rolling display systems currently employ flexible displays that are rolled into a case for facilitating a storage of the flexible display therein, and unrolled out of the case for facilitating an operation of the flexible display.
- An example of such a rolling display system is disclosed in U.S. Patent Application Publication No. 2002/0196205 Al.
- the flexible display can be wrapped around various display driving components within the case whereby either a rolling radius of the flexible display must be large enough to support immobile display drive components within the case and/or movement among display drive components within the case is required to facilitate the rolling/unrolling of the flexible display.
- One drawback to this rolling/unrolling approach of the flexible display are the limitations imposed on a construction of an optimal shape of the case with minimal dimensions for purposes of achieving a highest degree of portability of the case at minimal cost.
- One solution to this drawback is a wrap display system having a flexible display that is wrapped around a stick for facilitating a storage of the flexible display and unwrapped from the stick for facilitating an operation of the flexible display.
- the unwrapping of the flexible display from the stick requires the flexible display being flat and straight to facilitate an adequate readability of the flexible display.
- the display industry is therefore continually striving to improve upon an incorporation of a flexible display into a display system in view of achieving an adequate readability of the flexible display.
- the present invention provides new and unique structural forms of a wrap display system having a flexible display that is wrapped around a stick for facilitating a storage of the flexible display and unwrapped from the stick for facilitating an operation of the flexible display.
- the wrap display system further includes a hinged frame structurally configured to support the flexible display.
- the hinged frame has a curvilinear configuration for fixing the flexible display in a storage position with respect to the stick in response to the flexible display being wrapped around the stick.
- the hinged frame has a planar configuration for fixing the flexible display in an operational position with respect to the stick in response to the flexible display being unwrapped from the stick.

- One inventive principle of the present invention is to structurally configure a flexible display foil including an integration of a flexible display and a display cover that can be wrapped and unwrapped from around a stick.
- the present invention does not impose any limitations or restrictions as to the integration of the flexible display and the display cover.
- the term "integration" is broadly defined herein as an assembly of the flexible display and the display cover as a single unit, such as, for example, a mounting of the flexible display onto an external surface of the display cover, or a positioning of the flexible display within a multi-layered display cover where the flexible display is viewable through an open window or a transparent window of the display cover.
- a flexible display of the present invention can be a device provided by a company presently being organized called Polymer Vision Ltd., which has a layered flexible display consisting of a back layer of a thin/organic film serving as a base, a middle layer of organic electronics serving as an active matrix for driving the images of the flexible display, and a top layer of an electronic ink printed on a sheet of plastic.

- a layered flexible display consisting of a back layer of a thin/organic film serving as a base, a middle layer of organic electronics serving as an active matrix for driving the images of the flexible display, and a top layer of an electronic ink printed on a sheet of plastic.
- a flexible display foil 20 employs a flexible display 21 and a display cover 22 integrated relative to a display section 23 of display cover 22.
- An attachment section 24 of display cover 22 facilitates a coupling of flexible display foil 20 to a stick in any conventional manner.
- the dimensions of attachment section 24 can be selected to be less than, equal to or greater than a perimeter of the stick.
- a portion of attachment section 24 can be coupled to an external surface and/or an interface surface of the stick, and/or a portion or an entirety of attachment section 24 can be permanently wrapped around the stick.
- An optional control section 25 of display cover 22 facilitates a construction of a keyboard or any other type of mechanism for controlling flexible display 21 as needed.
- a second inventive principle of the present invention is to structurally configure a hinged frame having a curvilinear configuration for fixing a flexible display in a storage position with respect to a stick when the flexible display is wrapped around the stick (i.e., a body having a tubular configuration having a circular, elliptical, rectangular with rounded corners, square with rounded corners or any other curvilinear cross-section).
- the hinged fringe is further structurally configured under the second inventive principle of the present invention to have a planar configuration for fixing the flexible display in an operational position with respect to the stick when the flexible display is unwrapped from around the stick (i.e., a flat and straight configuration of a viewing screen of the flexible display within a single plane).
- a hinged frame of the present invention employs one or more rigid base supports and one or more hinge supports for supporting a flexible display.
- FIG. 2 provides an exemplary embodiment of a hinged frame employing two (2) rigid base supports and two (2) hinge supports.
- a hinged frame 30 of the present invention partially encircling flexible display foil 20 with attachment section 24 being unobstructed by hinged frame 30.
- Hinged frame 30 employs two (2) rigid base supports 31 and 32 and two (2) hinge supports 33 and 34, with each support 31-34 vertically extending across flexible display foil 20.
- Hinge support 33 is hinged to rigid base support 31 whereby hinge support 33 is pivotable relative to rigid base support 31.
- Hinge support 33 may also be hinged to a stick whereby hinge support 33 would be additionally pivotable relative to the stick.
- Hinge support 34 is hinged to rigid base supports 31 and 32 whereby hinge support 33 is pivotable relative to rigid base supports 31 and 32.
- FIG. 3 illustrates three (3) display segments DS1-DS3 of a flexible display in a curvilinear profile of the flexible display involving display segments DSl and DS3 having a planar shape and display segment DS2 being in a curved shape of an approximately constant radius Rl designed to uniformly wrap display segment DS2 around a stick.
- approximately constant radius Rl is meant that although preferably the radius Rl of the display segment D2 may be constant, the radius may show a deviation of about max 35% between the connection with the neighboring display segment (DSl, DS3) and the middle of the display segment D2 between both connections.
- the profile of the display segment DS2 is adapted to that of the end portion of the stick and it is still possible to uniformly wrap display segment DS2 around the stick.
- a larger deviation will result in too large risk of damage of the display and for an unacceptable volume of the stick.
- the deviation of Rl is about 3-6%.
- the display segment DS2 may show a substantially elliptical arch with locally a smaller, approximately constant Rl from the connection with the neighbouring display segment DSl, DS3 and a larger Rl in the middle of segment DS2.
- the profile of the display segment is adapted to the profile of the end portion of the stick that shows a somewhat flattened surface at the top.
- FIGS. 3 and 4 illustrates the flexible display in a planar profile involving all of the display segments DSl- DS3 having a planar shape.
- display segments DSl and DS3 are to be adjacent and attached to rigid base supports of a hinged frame and therefore will always be in planar profile irrespective as to whether the flexible display is wrapped around a stick or unwrapped from around the stick.
- display segment DS2 is to be adjacent and unattached to a hinge support of the hinged frame.
- an identification of attachment points API and AP2 as endpoints of display segment DS2 is essential to ensure that display segment DS2 is uniformly stowed over its entire length Ll within an adjacent hinge support in response to being in the curvilinear profile shown in FIG. 3 and to ensure that display segment DS2 is flat and straight over its entire length Ll relative to the adjacent hinge support in response to being in the planar profile shown in FIG. 4.
- FIG. 5 illustrates a hinge support having an arch segment ASl hinged to a rigid base support BSl at a hinged point HPl and an arch segment AS2 hinged to a rigid base support BS2 at hinged point HP3 with arch segments ASl and AS2 being hinged at hinge point HP2.
- a distance Dl between hinge points HPl and HP3 extends across arch segment ASl.
- a distance D2 between hinge points HP2 and HP3 extends across arched segment AS2.
- a distance D3 (shown in FIG. 6) between attachment point API and hinge point HPl extends along rigid base support BSl whereby D3 > 0.
- a distance D4 shown in FIG. 6) between attachment point AP2 and hinge point HP3 extends along rigid base support BS2 with distance D4 preferably equaling distance D3.
- a summation of distances D1-D4 must equal length Ll of display segment DS2 to ensure display segment DS2 is uniformly stowed over it entire length Ll within arch segments ASl and AS2 when display segment DS2 has the curved shape shown in FIG. 5 based arch segments ASl and AS2 being in a closed state, and to ensure that display segment DS2 is flat and straight over its entire length Ll relative to arch segments ASl and AS2 when display segment DS2 has the planar shape shown in FIG. 6 based on arch segments ASl and AS2 being in an open state.
- a wrapped radius of arch segment ASl and arch segment AS2 is based on the wrapped radius Rl of display segment DSl (FIG. 3) and is determinative of distances D3 and D4.
- FIGS. 7 and 8 illustrate a hinge support having a single arch segment AS3 hinged to rigid base support BSl at a hinged point HP4 and hinged to rigid base support BS2 at hinged point HP5.
- a distance D5 between hinge points HP4 and HP5 extends across arch segment AS3.
- a distance D6 between attachment point AP3 and hinge point HP4 extends along rigid base support BSl whereby D6 > 0.
- a distance D7 between attachment point AP4 and hinge point HP5 extends along rigid base support BS2 with distance D7 preferably equaling distance D6.
- a summation of distances D5-D7 must equal length Ll of display segment DS2 to ensure display segment DS2 is uniformly stowed over it entire length Ll within arch segment AS3 when display segment DS2 has the curved shape shown in FIG. 7 based on arch segment AS3 being in a closed state, and to ensure that display segment DS2 is flat and straight over its entire length Ll relative to arch segment AS3 when display element DS2 has the planar shape shown in FIG. 8 based on arch segment AS3 being in an open state.
- a radius of arch segment AS3 is based on the wrapped radius Rl (FIG. 3) of display segment DS2 and is determinative of distance D2 and distance D3.
- a third inventive principle of the present invention is to structurally configure a stick (e.g., any type of hollow body suitable for wrapping an object around) to support an optimal structural configuration of its internal components (e.g., driving electronics, connectors, etc.) and its external components (e.g., buttons and interface slots) without requiring any movement of these components upon a wrapping of a flexible display foil (e.g., FIG. 1) on the stick or an unwrapping of the flexible display foil from around the stick.
- the present invention does not impose any limitations or restrictions to the structural configuration and material composition of the components of a stick of the present invention.
- the specific implementations of a stick of the present invention is dependent upon the commercial implementations of the present invention, and are therefore without limit.
- FIG.' s 9 and 10 provides exemplary embodiments of sticks incorporating the aforementioned third inventive principle of the present invention.
- a stick 40 employs a cylindrical housing 41 defining a cavity 42 therein that facilitates a fixed incorporation of internal components in a standard configuration (e.g., a printed circuit board).
- a cross-section of cylindrical housing 41 can be circular, elliptical, rectangular with rounded corners, square with rounded corners or any other curvilinear cross-section, and an outside radius of cylindrical housing 41 at any point should not be less than a minimum roll-up radius of a flexible display employed within the present invention.
