DETAILED DESCRIPTION
[0034] The following describes specific embodiments of the present invention in detail. These described embodiments are illustrative only. Like reference numerals refer to like elements throughout. Relative terms such as outer and outside as used herein are to be understood in relation to the exterior of a bag. Similarly, terms such as inner and inside as used herein are to be understood in relation to the interior of a bag.
[0035] While the embodiments below are discussed primarily in relation to sports bags, it will be readily appreciated that the present invention may equally be applied to other types of bags including, for example, insulated food delivery/transportation bags.
[0036] A first embodiment of the invention is shown in
[0037]
[0038] The display screen module 103 comprises an electronic display 104 and an image controller 106. Preferably the electronic display 104 is a flexible display screen. More preferably, the electronic display 104 is a flexible reflective display such as e-paper or similar. Advantageously, because reflective displays operate by reflecting ambient light rather than emitting light (in contrast to backlit displays), their viewing properties remain consistent under changing ambient lighting conditions. Thus the use of a reflective display in particular enhances the seamless appearance of the bag outer panel element 100. For example, use of reflective display (especially when combined with the sheet of plastic material described below) may disguise the fact that an electronic display is present at all, the bag on which the bag outer panel element 100 is installed appearing as any normal bag until the image displayed on the (reflective) electronic display 104 changes.
[0039] The bag outer panel element 100 also comprises an optically clear element 126, which is optically coupled to the electronic display screen 104 by a non-gaseous optically clear medium (e.g., an optically clear adhesive and/or other optically clear liquid, solid or gel materials). This optical coupling advantageously reduces internal reflections and improves the contrast of images displayed on the electronic display as seen through the optically clear element 126. The optically clear element 126 also serves to provide protection and optionally additional support to the electronic display screen. In the embodiment illustrated in
[0040] Also shown in
[0041] The display controller 108 is configured to control the content displayed on the electronic display 104. For example, the display controller 108 may cause the electronic display 104 to display dynamic/changing advertising content, according to predetermined conditions (for example location or time during a sports competition), or external triggers (such as sale of advertising time). Optionally, the display controller 108 includes, or is communicably coupled to a wireless communication module (not shown) in order to receive external instructions on what content to display of the electronic display 104. Advantageously, the invention can thus dynamically change the content displayed on a bag without the need to manually remove markings from the bag.
[0042] Optionally, the bag outer panel element 100 includes further electronic components such as a location module (e.g. a GPS module) and a motion detection module (e.g. an accelerometer, inertial measurement unit, etc.). In these examples, the display controller 108 is configured to change the content displayed on the electronic display 104 responsive to a signal from the further electronic components. For example if the location of the bag changes, or if the bag moves, a signal can be sent to the display controller 108 from the location module and/or the motion detection module, causing the display controller 108 to change what is displayed on the electronic display 104.
[0043] Though shown as being part of the bag outer panel element 100, the display controller 108, battery 110, and any wireless communication module may be communicably coupled to the electronic display but positioned within the bag remote from the bag outer panel element 100.
[0044] In this embodiment, the display screen module 103 is housed within a recess 128 of the support 102. Advantageously this provides a convenient means for assisting aligning (during manufacture), securing and also protecting the display screen module 103. As shown, the recess 128 has a varying depth to accommodate the electronic display 104 and the image controller 106. However it will be appreciated that a recess having a different profile can be provided according to the profile of the display screen module 103 being housed.
[0045] The support 102 itself is preferably formed from a plastics material. Preferably the support 102 in this embodiment is relatively hard, however the support may have a degree of flexibility. Possible materials for forming the support 102 include composite moulded laminate, polycarbonate, injection-moulded plastic, and vacuum formed plastic. For example, polycarbonate having a thickness of between 0.5 mm and 3 mm is suitable.
[0046] Optionally, some electronic components such as the battery 110 and the display controller 108 are positioned between the support 102 and a protective panel 114, the protective panel 114 and the support 102 being attached by means of a frame 112. The protective panel may be formed of any suitable material, such as a rigid or semi-rigid plastics material. Preferably the protective panel has a material and dimensions such that its stiffness is the same as or similar to the stiffness of the support 114. The protective panel 114 may be attached to the frame 112 by any suitable attachments means, for example by an adhesive and/or one or more screws. In the event that the electronic component protected by the protective panel 114 include a wireless communication module, the protective panel 114 is preferably substantially transparent to, or includes a window that is substantially transparent to, electromagnetic radiation at wireless communication frequencies. Because the electronic display 104 is positioned on the opposite side of the support 102 to other electronic components, holes (not shown) are included in the support 102 to allow appropriate cabling to pass between components.
[0047] Optionally, any voids 130 between the support 102, the frame 102 and protective panel 114 not occupied by other components are filled or partially filed with a foam (not shown) or other material configured to support the various components and provide cushioning in the event of impact to the bag outer panel element 100.
[0048] To secure the bag outer panel element 100 to a bag outer panel or bag, the bag outer panel element 100 includes attachment means 116. The attachment means 116 can be any suitable attachment means, for example: a zip fastener/clasp locker configured to interact with a corresponding zip fastener/clasp locker on the bag; magnets/magnetic material configured to interact with a magnetic material/magnet on the bag; a hook/loop fastener configured to interact with a loop/hook fastener on the bag; an adhesive; staples; press studs; and sewn seams or holes configured to receive a thread for sewing to the bag. As will be appreciated, other suitable means can be provided to attach the bag outer panel element to a bag. The attachment means 116 are shown located proximate to a perimeter of the bag outer panel element 100 (for example extending around all or part of the perimeter of the bag outer panel element 100), though it will be appreciated that attachment means 116 could be located at other positions on the bag outer panel element 100.
[0049] Optionally, the bag outer panel element 100 includes a lip portion 118, such as a flange, the lip portion 118 extending from at least part of a periphery of the support and extending substantially towards an interior of a bag in use. As shown, the lip portion 118 generally extends at an angle with respect to the outer surface of the bag outer panel element 100/support 102. In the example of
[0050] In alternative examples, the attachment means 116 is attached directly to the support 102 without an intermediate tab.
[0051] Also shown in
[0052] As shown in
[0053] Alternatively, the optically clear element 126 is formed from an optically clear filler material (for example an optically clear epoxy), which is deposited onto the display screen module 103. Once the optically clear filler material has dried and/or cured, it is then sanded, ground or machined to the desired profile, and then polished such that the display module 103 is clearly visible through the optically clear filler material. In this arrangement, the optically clear filler material functions as both the optically clear element 126 and the optically clear medium that ensures optical coupling with the electronic display screen.
[0054] Though the extent of the optically clear element 126 is shown as corresponding to the extent (e.g. area) of the display screen module 103 in
[0055] Advantageously, the present embodiment allows for the bag outer panel element 100 to have a curved outer profile above the display screen module 103, as shown in
[0056] The optically clear element 126 is curved on an inside surface 127a and an outside surface 127b, in the first plane xz, to match the curvature of the electronic display screen 104.
[0057] To provide a compound curvature (i.e. curvature in more than two planes) on the outer surface of the bag outer panel element 100, the electronic display screen 104 and the inside surface 127a of the optically clear element 126 have little or no curvature in the second plane yz, while the outside surface 127b of the optically clear element 126 is provided with curvature in the second plane yz. Advantageously, this allows the bag outer panel element 100 to exhibit complex and compound curves (for example matching the natural curves that a bag would ordinarily have in absence of a bag outer panel element including a display), without subjecting the flexible electronic display to significant mechanical stress. To achieve the desired surface profile, in one example the optically clear element 126 is formed from optically clear epoxy resin applied to the display screen module 103 that, when set, is ground, sanded or machined to the correct profile and then polished to an optically clear finish.
[0058]
[0059] Optionally, the bag outer panel element 100 also comprises a solar panel (not shown), for example located within a further recess in the support 102 and electrically connected to the battery 110. The bag outer panel element 100 is thus beneficially a self-contained display unit which can function when attached to a bag even in the absence of external power connections.
[0060]
[0061] The installation jig 140 may be flexible and/or shaped to conform to the profile of a perimeter of the outer surface of the display screen module 103, (preferably with, but alternatively without the optically clear element 126 attached (for example following the curvature of the display screen module 103 or optically clear element 126 shown in
[0062] Preferably the optically clear element 126 is formed from sheet material or otherwise preformed, and is removably affixed to the installation jig 140 prior to assembly of the other components of the display screen module 103. Advantageously this allows the installation jig 140 to act as a support while assembling the other components of the display screen module 103. Alternatively, the optically clear element 126 is removably affixed to the installation jig 140 after two or more of the other components have been assembled (e.g. after the optically clear element 126 has been affixed to the flexible display screen 104). In a less preferred alternative, the display screen module 103 is removably attached to the installation jig 104 directly, and the optically clear element 126 is added after the display screen module 103 has been attached to the recess 128.
[0063] Optionally the optically clear element 126 (or display screen module 103) is removably affixed to the installation frame 340 using a temporary adhesive, for example using a double-sided adhesive tape between the optically clear element 126 (or display screen module 103) and the installation jig 140.
[0064] An adhesive is applied at a position proximate to the perimeter of the electronic display 104. The adhesive may either be applied: to a perimeter portion of the floor of the recess 128; to a perimeter portion of an inside surface (a surface facing the recess 128 in use) of the electronic display 104 or display screen module 103; to a perimeter portion of an inside surface (a surface facing the recess 128 in use) of the optically clear element 126 (particularly where the optically clear element 126 extends beyond the perimeter of the display module 103, as noted above); or a combination of the above. Alternatively the adhesive may be positioned at other locations between the recess 128 and the display screen module 103.
[0065] The installation jig 140 is then manoeuvred so as to position the display screen module 103 in the recess 128.
[0066] Preferably the installation frame 140, along with the electronic display screen 104, is flexible. In this example, when the electronic display screen 104 is brought into contact with the recess 128 using the installation frame 140, both the installation frame 140 and electronic display 104 are caused to flex, such that the electronic display screen 104 conforms to the shape of the recess and consequently the electronic display 104 is conformal with a surface profile of the recess 128 (for example continuing a profile of the support 102, in turning continuing or matching a surface profile of the bag outer panel). Alternatively, the installation frame 140 can be pre-formed to a shape that corresponds to the shape of the support 102.
[0067] In some examples a further external mounting jig (not shown) may be connected to the installation jig 140 and configured to hold the installation frame (and thus the assembled display screen module 103) in place during curing of the adhesive. Optionally such an external mounting jig can also be shaped to conform to the contours of the specific display screen module 103 being fitted. Alternatively, a temporary adhesive or other removable attachment means can be provided to temporarily secure the installation frame 140 to the support 102 during curing of the adhesive.
[0068] As shown in
[0069] In an example, the adhesive applied to the recess 128 and/or to the display module 103 is a UV curable adhesive, and the means for removably affixing the display screen module 103 (or optically clear element 126) to the installation frame 340 is at least partially transparent to UV radiation (for example double-sided adhesive tape). In this case, following positioning of the display screen module 103 within the recess 128, the adhesive is subjected to UV radiation (e.g. through the optically clear portion) through until cured. In this example, the mounting frame 140 optionally includes one or more UV light sources (for example a series of UV LEDs), configured to provide UV radiation to cure the UV adhesive.
[0070] After the adhesive has cured, the installation frame 140 is then removed from the optically clear element 126 (or display screen module 103). Any join line between the support and the now installed display screen module 103 is preferably then filled using a suitable filler material. The filler material is then smoothed if required.
[0071] Advantageously, use of the installation frame 140 increases the speed with which the bag outer panel element 100 can be accurately assembled, while ensuring that the outer surface of the optically clear element 126 is flush and in line with the contours of the surrounding support 102.
[0072] A second embodiment of the invention is shown in
[0073] The second embodiment provides a bag outer panel element 200a, 200b comprising, a display screen module 203 (comprising an electronic display 204), an image controller 206 and a display controller 208 (in this case shown as an integrated component), a battery 210, a protective panel 214, and an attachment means 216. These elements are substantially as described above in relation to the corresponding components of the first embodiment of
[0074] Again, any voids 230 between the support 202, the frame 202 and protective panel 214 not occupied by other components are optionally filled or partially filed with a foam (not shown) or other material configured to support the various components and provide cushioning in the event of impact to the bag outer panel element 200.
[0075] The bag outer panel element 200a, 200b comprises a support 202, which differs from support 102 of the first embodiment above. The support 202 includes an integral optically clear element 226 (in a preferred example the entire support 202 is made from optically clear material, such as optically clear plastics material). The display screen module 203 is non-releasably mounted to an underside of the optically clear element 226, such that images displayed on the electronic display 204 are visible through the optically clear element 226.
[0076] The support 202 itself is preferably formed from a plastics material. Preferably the support 202 in this embodiment is relatively hard and stiff, however the support may have a degree of flexibility. Possible materials for forming the support 102 include composite moulded laminate, polycarbonate, injection-moulded plastic, and vacuum formed plastic. For example, polycarbonate having a thickness of between 0.5 mm and 3 mm is suitable. Preferably the support 202 is produced as a curved panel with a perimeter shape and profile matching a desired final shape, using, for example vacuum forming techniques.
[0077] A frame 212 is also provided. The frame 212 optionally extends around a periphery of the support 202, for example at or proximate an edge of the support 202/around the outside of a periphery of the electronic display 204. The frame 212 is preferably made from a plastics material and has a stiffness (i.e., the extent to which an object resists deformation in response to an applied force) similar to (e.g., the same as) or greater than stiffness of the support 202. In some examples, the frame 212 is made from an injection-moulded or 3D-printed thermoplastic such as ABS or similar, or an injection-moulded fibre-reinforced thermoplastic, and has a thickness of around 10 mm. The material and shape of the frame 212 is chosen such that it exhibits a stiffness that it is similar to, equal to or greater than the stiffness of the support 202it will be appreciated that the precise shape and dimensions of the frame 212 will also depend on the desired end shape of the outer bag panel element 200a, 200b.
[0078] In addition to providing additional rigidity to the bag outer panel element 200a, 200b, the frame 212 advantageously provides for efficient manufacture of the bag outer panel element 200a, 200b. During manufacture, the frame 212 is preferably preformed, and the support 202 is subsequently bent around and affixed to the support. Thus, the frame 212 can be shaped so as to hold the support 202 in a desired curved profile, without having to otherwise shape, mould or preform the support 202 itself. In some examples, the frame 212 is affixed to the underside of the support 202 as shown in
[0079]
[0080]
[0081] As with the first embodiment, the second embodiment advantageously provides a means for providing a bag outer panel element 200a, 200b having compound curves without introducing undue stress to the electronic display 204. As shown in
[0082] Preferably, the support 202 including optically clear element 226 is preformed to the desired profile (e.g. having a compound curved profile). In this example, during manufacture, an optically clear adhesive is applied to the inside surface of the support 202 proximate to the optically clear element 226. The electronic display screen 104 is then flexed (e.g. with curvature in one plane) if required, and brought into contact with the adhesive. Alternatively, the optically clear adhesive can be applied to the electronic display screen in addition to/instead of support 202 before bringing the two components together. This ensures good optical coupling between the optically clear element 226 and the electronic display screen 204.
[0083]
[0084]
[0085] The third embodiment provides a bag outer panel element 400 comprising, a display screen module 403 (comprising an electronic display 404), an image controller 406 and a display controller 408 (either as a single integrated component or as individual components), a battery 410, a protective panel 414, and an attachment means 416. Optional solar panel 432 is also provided. These elements are substantially as described above in relation to the corresponding components of the first embodiment. Further optional electronic components (e.g. wireless communication, location detection and motion detection modules) as described in relation to the first embodiment above are similarly optionally provided in this second embodiment.
[0086] As with the second embodiment, a support 402 is provided to which the display screen module 403 is non-releasably mounted, the support 402 including an integral optically clear portion 426 (for example the entire support 402 may be made from optically clear material, such as optically clear plastics material). The display screen module 403 is mounted to an underside of the optically clear portion 426 (for example using optically clear adhesive such as a suitable double-sided adhesive tape, or a liquid adhesive), such that images displayed on the electronic display 404 are visible through the optically clear portion 426. As with the above embodiments, the electronic display screen 404 is optically coupled to the optically clear portion 426, such that any gap between the electronic display screen 404 and the optically clear portion 426 is substantially filled with a non-gaseous optically clear intermediate medium (e.g. a gel, solid or liquid material such as a suitable adhesive). A frame 412 is preferably provided, which optionally has the same properties and functionality as the frame 212 described above in relation to the second embodiment. Alternatively, the frame 412 has a similar or lower stiffness than the support 402, so as not to impede flexing of the support 402in some examples, the frame 412 is made from a flexible foam material.
[0087] In a variation of this embodiment, the frame 412 is omitted, and the protective panel is attached directly to the support 402. This is shown in
[0088] Any, voids 430 between the support 402, and protective panel 414 not occupied by other components are optionally filled or partially filed with a foam (not shown) or other material configured to support the various components and provide cushioning in the event of impact to the bag outer panel element 400.
[0089] In this embodiment, the electronic display 404, the support 402 and the protective panel 414 are all flexible, allowing the bag outer panel element 400 to flex. This arrangement is particularly advantageous for use on bag panels which typically undergo flexing in use. In a preferred embodiment, the support 402 is made from a flexible plastics material with a modulus of elasticity of less than 100 MPa, for example less than 50 MPa or less than around 30 MPa (at room temperature), for example around 1.5 to 15 MPa or around 1.5 to 20 MPa, such as PVC-P (plasticized polyvinylchloride) TPU (thermoplastic polyurethane), or PEVA (polyethylene vinyl acetate). PVC-P at thicknesses between 0.25 and 1 mm has been found to display suitable deformation properties. Alternatively, other suitable plastics materials and thicknesses may be used.
[0090] In this embodiment, the non-gaseous optically clear intermediate medium comprises an optically clear stiffening layer 405 disposed between the support 402 and the electronic display screen 404. The stiffening layer 405 is fabricated from an optically clear plastics material, and is fixed to the optically clear portion 426 and the electronic display screen 404 in such a way as to ensure good optical coupling to both the optically clear portion 426 and the electronic display screen 404 (for example by using an optically clear adhesive. The intermediate stiffening layer 405 has a stiffness that is greater than the stiffness of the support 402, and less than the stiffness of the flexible electronic display 404. In one example, the intermediate layer is a sheet of optically clear polycarbonate with a thickness of less than 1 mm. Advantageously, the intermediate stiffening layer 405 provides a transition in stiffness between the (preferably flexible) electronic display screen 404 and a more flexible support 402, such that any discrepancy between the stiffness of the electronic display screen 404 and the support 402 is less apparent. In particular, the use of the intermediate stiffening layer 405 helps reduce or avoid occurrence of a sharp bend in the support 402 at the point where the support 402 meets a peripheral edge of the electronic display screen 404, when the display screen module 403 as a whole is bent. Instead, the intermediate stiffening layer 405 ensures a less discontinuous curvature across the display screen module 403.
[0091] In this embodiment, the support 402 optionally does not include a lip portion, thereby enhancing the flexibility of the bag outer panel element 400.
[0092] As shown in
[0093] In any of the first, second or third embodiments, the support 102, 202, 302, 402 and/or the optically clear element 126, 226, 426 may include surface coating or decoration to disguise the edges of the display screen module 103, 203, 403, further seamlessly integrating the display screen module 103, 203, 403 into the bag or bag outer panel.
[0094]
[0095]
[0096]
[0097] Though the electronic displays 504, 604 shown in
[0098] In general, the bag outer panel elements 100, 200a, 200b, 300, 400 described above may be attached to an existing bag outer panel on a bag, or replace an existing bag outer panel (that is, attaching the bag outer panel element 100, 200a, 200b, 300, 400 to the bag completes the bag). In this way, traditional bag construction is maintained by the invention: the embodiments above augment an existing bag or bag design, rather than replace it with an entirely new bag design.
[0099] Preferably outside surfaces of the bag outer panel elements 100, 200a, 200b, 300, 400 described above are covered with a sheet of clear plastic (e.g. vinyl) film (not shown) comprising a surface texture that matches, or is complimentary to a surface texture on a part of the bag that the bag outer panel element 100 is being attached to. The clear plastic film preferably includes a clear section (positioned at least partially above the optically clear portion) and at least one coloured section (the colour preferably chosen to match a colour to be displayed on the electronic screen 104 204, 304, 404). Optionally the sheet of clear plastic film includes a marginal region fading from the coloured section to the clear section. The clear plastic film may be pre-coloured, or alternatively painted or printed to as to have the achieve the required coloured and marginal section. These features advantageously disguise the presence of the electronic screen 104 204, 304, 404 on the bag.
[0100] Thus, there are a wide range of economic and effective systems in the present invention that allow the display of images that appear to be seamlessly present within a bag outer panel, yet can be altered at will. This permits their use as part of a sponsorship or advertising deal, such that selected images can be displayed at different positions or times during a sports competition or any other commercially desirable conditions.
[0101] In one example, the content displayed on the electronic display screen 104, 204, 304, 404, 504, 604 is determined and controlled according to method 700 as shown in
[0102] At step S704 one or more instructions for generation of an image (e.g. an advertising image) on the display screen module 103, 203, 403 are provided to the display controller 108, 208, 308, 408. Such instructions include the data required for the display controller 108, 208, 308, 408 to cause the electronic display screen 104, 204, 304, 404, 504, 604 to display the image.
[0103] At step S706, one or more conditions under which an image is to be displayed are defined. The one or more conditions optionally include any combination of the following: a specific time, date or period of time; the bag being at a first location, wherein the control means includes a location determining means; and receipt, by the display controller 108, 208, 308, 408, of a signal from an external source (for example an external server or from a local sensor).
[0104] At step S708, the defined one or more conditions are then provided to the display controller 108, 208, 308, 408 (for example by storing the one or more conditions at the display controller 108, 208, 308, 408, and/or transmitting the one or more conditions to the control means from an external server, in which case a wireless communications module is preferably provided at the bag outer panel element 100, 200, 300, 400, 500, 600).
[0105] It will be appreciated that steps S704, S706 and S708 may be performed in different temporal sequences. For example, rather than send instructions first in step S704, the instructions may be provided to the display controller 108, 208, 308, 408 at the same time as the conditions (i.e. step S706 is performed, then steps S704 and S708 are performed together).
[0106] In step S710, the display controller 108, 208, 308, 408 then controls the electronic display screen 104, 204, 304, 404, 504, 604 such that the image is displayed responsive to the display controller detecting that the one or more conditions are satisfied. This optionally involves the display controller 108, 208, 308, 408: detecting that a specific time, date or period of time has been reached (for example corresponding to the time/date/period of time of a sporting event or a particular match, using an internal clock or based on a received signal indicative of time); detecting that the bag is at a first location (for example the bag 50, 60 has arrived at a sports venue, at a press conference area, etc., using an optional location detection module); or receiving a signal from a local/internal sensor (e.g. a motion detection module) or from an external source (e.g. an external server), the signal indicative that the image is to be shown. For instance, advertising time using the bag outer panel element 100, 200, 300, 400, 500, 600 may be sold on a timed basis, and an external server may send a signal to the display controller 108, 208, 308, 408 to display a particular image in accordance with an advertising time slot being sold.
[0107]
[0108] At step S802, a support 102, 202, 302, 402 is provided. The support 102, 202, 302, 402 is optionally preformed to the desired shape or profile, for example by vacuum forming or moulding. Where the support 202 includes an optically clear element 226 (or where the support 202 is entirely optically clear), the support 202 is alternatively affixed to a frame 212, which frame may be preformed such that the support takes on the desired shape or profile when it is affixed to the frame (e.g., the support 202 is bent around the frame 212).
[0109] At step S804, a display screen module 103, 203, 403 comprising an electronic display screen 104, 204, 304, 404, 504, 604 is mounted (preferably non-releasably mounted) to the support 102, 202, 302, 402. Depending on the form of the support 102, 202, 302, 402, step S804 may involve different activities.
[0110] Where the support 202 includes an optically clear element 226 (or where the support 202 is entirely optically clear), an optically clear adhesive is preferably applied to the support 202 proximate to the optically clear element 226 (or to the display screen module 203). The display screen module 203 is then attached to the optically clear element 226 via the optically clear adhesive, such that the display screen module 203 is optically coupled to, and visible through, the optically clear element 226 (step S805). The optically clear adhesive preferably fills any gap between the display screen module and the optically clear element 226. Optionally, the display screen module 203 is flexed so as to have curvature in at least one plane prior to attaching to the optically clear element 226. Accordingly the method enables effective manufacture a bag outer panel element 200 where the display screen module 203 is positioned beneath a support 202, having good optical properties and a surface profile with complex, e.g. compound curvature.
[0111] Where the support 102 includes a recess 128, at step S806 the display screen module 103 is preferably removably attached to an installation jig or frame 14 (either with or without an optically clear element 126 affixed). Optionally, the optically clear element 126 is already attached to, and forms part of, the display module 103 prior to the display module 103 being removably attached to the installation jig in step S806. The installation jig 140 is configured to lie substantially flush with at least a perimeter of an outer surface of the optically clear element 126 (either because the installation jig 140 is flexible, or preformed to the appropriate shape, or both), and the installation jig 140 has outside dimensions 152 greater than corresponding outside dimensions 150 of the display screen module such that the installation jig 140 extends beyond edges of the display screen module 103. Step S806 further comprises affixing the display screen module 103 to the recess 128, e.g. by means on an adhesive, while the electronic display screen 104 is attached to the installation jig 140 (for example by bringing the installation jig 140 into contact with the support 102 such that the installation jig 140 overlaps both the support 102 proximate to the recess 128 and the display screen module 103); and removing the installation jig 140 from the display screen module 103. As shown, the installation jig 140 has a central cut-out, though it will be appreciated that the installation jig 149 may alternatively be continuous, and have a variety of shapes/profiles according to the shape of the support 102 and other components of the bag outer panel element. Advantageously, use of the installation jig 140 enables accurate alignment of components during manufacture, and helps ensure a flush join between the display screen module 103 and the support 102. The method thus provides an effective and accurate means for manufacturing bag outer panel elements 100. Optionally, the installation jig 140 comprises one or more UV radiation sources, and step S806 also comprises: applying UV curable adhesive to at least one of the display module 103 and the recess 128; positioning the electronic display screen 104 within the recess 128; and applying UV radiation to the UV curable adhesive using the one or more UV radiation sources. Advantageously this provides a particularly convenient means for securing the display screen 103 module to the recess 128.
[0112] Either before, during or after step S804 (e.g. involving either step S805 or step S806), step S808 is performed, in which an attachment means 116, 216, 316, 416, 516 configured for attachment to a bag outer panel or a bag 50, 60 is connected to the support 102, 202, 302, 402. For example, the attachment means 116, 216, 316, 416, 516 is either connected directly to the support 102, 202, 302, 402, or connected via an intermediate tab 120, 220. The attachment means 116, 216, 316, 416, 516 or tab 120, 220 is optionally attached to the support 102, 202, 302, 402 using adhesive and/or a sewn seam.
[0113] Either before, after, or contemporaneously with the steps above, at step S810 a control means (for example a display controller 108, 208, 308, 408) is provided, which is operatively connected or connectable to the display screen module 103, 203, 403. The control means is adapted to control the electronic display screen 104, 204, 304, 404, 504, 604 to display a selected image, for example using the method 700 described in relation to
