DETAILED DESCRIPTION

[0015] The following description of variously embodied backlit display systems is demonstrative in nature and is not intended to limit the invention or its application of uses. Accordingly, the various implementations, aspects, versions and embodiments described in the summary and detailed description are in the nature of non-limiting examples falling within the scope of the appended claims and do not serve to restrict the maximum scope of the claims. Moreover, among the various depicted embodiments, like reference numbers are used to refer to similar or analogous components.

[0016] Referring initially to FIG. 1, a first embodiment of a backlit display system 10 includes a display framework 20 and a display fabric 50 configured for fitting over the framework 20. The display framework 20 has frame front and rear sides 22 and 24 and an outer and inner perimeter 25.sub.o and 25.sub.i. The inner perimeter 25.sub.i defines a central open space S.sub.O. A plurality of light-emitting elements 28 is disposed along the inner perimeter 25.sub.i of the display framework 20, and peripherally disposed about the central open space S.sub.O, such that, when they are operatively energized, the light-emitting elements 28 emit light into the central open space S.sub.O.

[0017] The display fabric 50a cutaway view of which is depicted in FIG. 1has mutually distinct image-display and back-lighting panels 52 and 54. The image-display panel 52 defines a displayed image I.sub.D (alternatively, image I.sub.D) which is, by way of non-limiting example, printed onto the portion of the display fabric 50 constituting the image-display panel 52 or woven of disparately-colored fibers defining the image I.sub.D. When the backlit display system 10 is operatively assembled, the display fabric 50 is supported by and about the display framework 20 such that (i) the back-lighting panel 54 is adjacent to and rearward of the frame rear side 24 and the image-display panel 52 is adjacent to and forward of the frame front side 22. Moreover, the image-display and back-lighting panels 52 and 54 are mutually opposed with at least a portion of the central open space S.sub.O situated between them.

[0018] With the backlit display system 10 thusly assembled, the image-display panel 52 has an inside surface 52.sub.SI facing the central open space S.sub.O and an outside surface 52.sub.SO facing away from the central open space S.sub.O and forwardly of the display framework 20. The back-lighting panel 54 has at least an interior surface 54.sub.SI that is at least partially reflective (i.e., light-reflective) and an exterior surface 54.sub.SE. The image-display panel 52 is at least partially light-permeable such that a portion of the light L that is emitted from the light-emitting elements 28 and reflected by the interior surface 54.sub.SI of the back-lighting panel 54 impinges upon the inside surface 52.sub.SI of the image-display panel 52 and exists through the outside surface 52.sub.SO of the image-display panel 52. The displayed image I.sub.D is thusly illuminated (i.e., backlit) by the passage of light L through the fabric image-display panel 52.

[0019] In various embodiments, the display fabric 50 is comprised of tension fabric. Tension fabric is somewhat stretchable and exhibits a memory property. Accordingly, a display fabric 50 that is properly sized and configured relative to the display framework 20 is such thatwhen supported by the display framework 20 in a display-operative modeat least the image-display panel 52 is taut (e.g., stretched under tension). It will be appreciated that configuring the display fabric 50 and display framework 20 in observance of such parameters facilitates a displayed image I.sub.D that is smooth and free of creases and wrinkles. Still additional embodiments are such that both the back-lighting and image-display panels 54 and 52 are taut when the display fabric 50 is supported by the display framework 20 in a display-operative mode.

[0020] In still more specific versions, the image-display and back-lighting panels 52 and 54 are mutually joined along their peripheries so as to define a slip-cover having an opening 56 through which the display framework 20 can be introduced. With reference to the illustrative version of FIG. 1, each of the image-display and back-lighting panels 52 and 54 is generally rectangular. The image-display panel 52 is bounded by a display-panel periphery 52.sub.P, while the back-lighting panel 54 is bounded by a lighting-panel periphery 54.sub.P. The peripheries 52.sub.P and 54.sub.P are joined to one another along three of four edges in order to define a display fabric 50 that resembles a pillow case. The particular means by which the panel peripheries 52.sub.P and 54.sub.P are joined is of no direct materiality to the points of novelty, but they could be permanently joined by stitching, for example, or temporarily joinable and separable by snaps or a zipper, by way of non-limiting example.

[0021] In various embodiments discussed with principal reference to the illustrative version of FIG. 2, the display framework 20 is modular. More specifically, in the version of FIG. 2, the display framework 20 is comprised of a plurality of frame segments 30, which in the particular illustrative, non-limiting embodiment shown, are tubular. Each tubular frame segment 30 includes a segment male end 32 and a segment female end 34 between which ends 32 and 34 there extends a hollow interior segment channel 35. Two adjacent frame segments 30 are joined by fitting the segment male end 32 of a first segment 30 into the segment female end 34 of the adjoining frame segment 30, in very much the same manner in which various types of tent and canopy poles are configured and assembled. Although tubular frame members are frequently cylindrical, tubular frame segments 30 of various alternative cross-sectional geometries are within the scope and contemplation of the invention.

[0022] Referring to FIG. 2A, some embodiments include tubular frame segments 30 that are themselves comprised of tubular frame sub-segments 40. Like the frame segments 30 of which they form a part, each frame sub-segment 40 includes a sub-segment male end 42 and a sub-segment female end 44 between which ends 42 and 44 there extends a hollow interior sub-segment channel 45. Two adjacent sub-segments 40 are joined by fitting the sub-segment male end 42 of a first sub-segment 40 into the sub-segment female end 44 of the adjoining frame sub-segment 40. The top portion of FIG. 2A shows an assembled frame segment 30, while the bottom portion of FIG. 2A depicts a disassembled frame segment 30.

[0023] It will be readily appreciated that, when at least two frame sub-segments 40 are cooperatively coupled to form an assembled frame segment 30 (top portion of FIG. 2A), the sub-segment male end 42 of the frame sub-segment 40 at one end of the frame segment 30 constitutes the segment male end 32, while the sub-segment female end 44 at the opposite end of the frame segment 30 constitutes the segment female end 34. In various configurations, the frame sub-segments 40 of a frame segment 30 are mutually linked by a flexible tether 46. More specifically, a first end 46A of the tether 46 is joinedwithin the sub-segment channel 45to a frame sub-segment 40 at one end of the frame segment 30, while a second end 46B of the tether 46 is joinedwithin the sub-segment channel 45to a frame sub-segment 40 at the opposite end of the frame segment 30. Furthermore, the tether 46 passes through the sub-segment channels 45 of all sub-segments 40 by which the frame segment 30 is defined. In addition to being flexible, the tether 46 is preferably elastic in order to accommodate the separation of sub-segments 40, while avoiding slack as the sub-segments 40 are mutually joined.

[0024] The foregoing is considered to be illustrative of the principles of the invention. Furthermore, since modifications and changes to various aspects and implementations will occur to those skilled in the art without departing from the scope and spirit of the invention, it is to be understood that the foregoing does not limit the invention as expressed in the appended claims to the exact constructions, implementations and versions shown and described.
