This application is a 35 U.S.C. § 371 national stage application of PCT International Application No. PCT/GB2019/000091, filed on Jun. 28, 2019, which claims the benefit of Great Britain Application No. 1810799.5, filed Jun. 29, 2018 and Great Britain Application No. 1817103.3, filed Oct. 19, 2018. The contents of the above patent applications are hereby incorporated by reference in their entirety.
The present invention relates to a display screen mounted to a vehicle, to its method of manufacture and to its method of use. More particularly but not exclusively, it relates to a display screen integrated into bodywork of a car, especially a racing car. It further relates to such a display screen incorporated into a vehicle rider's protective clothing.
In the field of racing cars, whether Formula 1, Indycar, Le Mans or other types of racing, the bodywork of the car has two significant roles. The carefully-designed curvature of the bodywork provides an aerodynamic surface to optimise airflow over the car, reducing drag and providing aerodynamic downforce to hold the car to the track. Additionally, in the highly commercial area of motor sport, the bodywork provides advertising space to show sponsors' names and/or logos to best effect. For many types of racing car, these are the main roles of the bodywork, with structural loads being taken up by an internal chassis, mainly concealed within the bodywork.
Race car construction falls broadly into two main categories. One category of race car is mostly derived from production motor cars, which nowadays have a unitary metal construction to which additional components are bolted, usually including a supplementary internal roll cage for additional driver protection. This category will be referred to herein as the “GT car” category.
The other main category makes extensive use of custom-built carbon fibre composite materials, usually consisting of a strong and relatively heavy chassis of carbon fibre composites and aluminium honeycomb, to which the engine and suspension/wheels are mounted, with lightweight body panels of carbon fibre composite and polymer honeycomb being bolted around the chassis to create the aerodynamic bodywork and to provide an aesthetic outer surface to bear the team colours and sponsor logos, etc. This category will be referred to herein as the “Formula Car” category.
Popular examples of GT Cars include Nascar and International Touring Car, while popular examples of Formula Cars include Formula 1, Indycar and Le Mans Prototype (LMP). For some time now, Formula 1 has been considered to be the pinnacle of Formula Car racing, with much cutting-edge automotive technology being developed in Formula 1, before trickling down to other racing car categories, and often (eventually) to mass-production motor vehicles. (Note: Formula 1 is a registered trade mark of Formula One Licensing BV; Indycar is a registered trade mark of Brickyard Trademarks, Inc; Nascar is a registered trade mark of National Association for Stock Car Auto Racing, Inc).
Weight reduction plays a crucial part in the Formula Car category, with the result that the outer body panels are usually constructed from two very thin plies of carbon fibre composite sandwiching a core of honeycomb Nomex sheet or the like (Nomex is a registered trade mark of EI Du Pont for its meta-aramid flame-resistant woven and non-woven materials). The bodywork panels are hence very light but relatively stiff, and since they only have to cope with aerodynamic loads not major structural loads, this is sufficient. However, they are susceptible to damage from other causes. The panels are particularly prone to puncture and abrasion damage, as well as delamination. This is not only an issue during races, but also during maintenance, including paint refinishing and replacement of vinyl sponsorship graphics.
For example, the force required to pull a vinyl graphic off the bodywork can be such that the outer ply of carbon fibre delaminates from the honeycomb core. Removing old paint for refinishing a bodywork panel generally involves scraping with a bladed tool. This can breach the outer surface of the carbon fibre ply, greatly weakening it and possibly leading to delamination of the carbon fibre ply from the honeycomb core during a race. The painting process also includes a sanding step for removing old paint and for preparing the surface to apply a new primer, and it is all too easy to sand through into the carbon fibre ply below.
Repair of such damage usually requires the application of additional layers of carbon fibre over the damage, or the use of structural adhesives and fillers to bond the damaged areas back together. Further filler will also be needed to restore the shape of the bodywork panel. All of these repairs add weight to the panel, which is to be avoided, either to maximise power to weight ratios, or to allow more of a rules-defined weight limit to be used on performance-enhancing components.
A further issue for motor racing teams is to keep down costs. Formula 1 teams, for example, usually travel directly from one track to the next during the season, rarely returning to their base of operations. Damaged bodywork may well require separate return to the base of operations for repair or refinishing in addition to normal logistic requirements. If a painted graphic on a bodywork panel is to be changed between races, e.g. due to new sponsorship deals, then the panel would again have to be returned to base to be modified and sent on to meet the team at its next event. Additional body panels will need to be carried, in case those being repaired or refinished are not ready in time or cannot be repaired. Thus, many different additional costs will occur as a result of the need to refinish panels or to change panels finishes voluntarily.
Yet another issue is time management. At many events, such as Formula 1 Grands Prix, limited amounts of time are available to work on the car. Time spent on processing bodywork repairs is time not spent on more fundamental issues. It is possible that bodywork panels and the like may not be available at convenient times, requiring unscheduled transportation or simply not being available for a race, due to insufficient time between events.
The business models of most motor racing teams are heavily dependent on sponsorship and hence on graphics on the cars to display this sponsorship. It is similarly essential to display the team's own branding on the cars. Advertising revenue will be dependent on showing relevant marks and graphics to best effect, and as responsively as possible to any changes. Voluntary changes in graphics are hence just as important as remedial work.
The application of graphics such as logos to race cars is currently carried out by two main methods, painting them on or applying pre-formed “graphics” of self-adhesive vinyl sheet.
Painted graphics give a very good visual finish, but disadvantages include the time taken to paint a design on to a bodywork panel; that complicated designs are difficult to apply and some have been found impossible to paint; and changing a graphic requires repainting. Overpainting is unacceptable, for example on weight grounds, and the old design has been known to show through the new one on top. Stripping off an old painted design produces a significant time delay before the new design can be applied. In any case, stripping the old paint causes wear and tear on the relatively fragile body panels. This can lead to more delay for repairing the wear and tear—which then adds to the weight of the panel anyway. Also, complex repainting requires specialist facilities not available at the race track, so panels have to be sent away, wasting time and increasing costs.
Thus, changing painted graphics has weight, cost and time implications. In extreme cases, these constraints may make it preferable to buy or produce extra bodywork parts for painting with different graphics. Ultimately, if an advertiser changes, and it is not possible to display the new advertising at the next race, the new advertiser will not pay and the old advertiser will benefit from free publicity.
Self-adhesive vinyl graphics have the benefit of rapid application and removal, but also have several disadvantages. A vinyl graphic has a significant thickness, causing a step on the surface of the bodywork. Such a step can be sufficient to interfere with smooth airflow across the surface of the bodywork, having an appreciable adverse effect on the aerodynamics of the race car. Such steps are frequently visible, producing a poor visual aesthetic. Close up to the car, the steps can be felt if a hand is run across the panel.
As referred to above, the removal of a vinyl graphic causes stresses in the underlying substrate, which can cause the underlying paint finish to peel off Thus, stripping and repainting will be needed, which themselves can result in wear and tear on the bodywork, leading to repairs, which add weight. The stress of peeling off a vinyl graphic can even lead to delamination of the structure of the bodywork panel itself, again requiring repair and added weight, or even replacement.
Application of a vinyl graphic has a finite chance of trapping air bubbles beneath the vinyl sheet, leading to an inferior visual aesthetic, or the need to peel off and reapply the graphic. This naturally runs a further risk of peeling off the paint or delaminating the layered bodywork structure.
In any case, vinyl graphics cannot be made with the high gloss levels of automotive paintwork, and are less smooth on a visible scale, both effects making the vinyl graphics stand out visually from the painted bodywork, making them appear low quality and aesthetically compromised.
Thus, the use of vinyl graphics also has weight, cost and time implications, largely arising from the real chance of damage to paint and bodywork laminates during removal. This leads to the same set of problems as for painted graphics, ultimately leading to the choice of having to procure more spare bodywork panels or being unable to change a graphic in time for the next race.
The need to change bodywork logos and other graphics so often stems from current methods for arranging advertising on race cars. While major teams usually have major sponsors and advertisers able to pay for a space on a car for a complete season of races, minor teams tend to rely more on a larger number of smaller advertisers, many of which will only be able to afford to rent space on the car for a few races. There is hence a need for frequent changes of graphics, every time one of the advertisers changes.
As shown above, it is difficult to change the graphics quickly and any changes can lead to bodywork damage. It is hence preferable to try to book advertising to appear over many races, and the most visible (and hence valuable) locations on the bodywork would ideally be committed to one advertiser/sponsor. This allows little commercial flexibility and it is hard to earn as much as if multiple advertisements could be shown. It would also tend to restrict advertising to multi-national companies, rather than allowing an advertiser to buy space on the bodywork for only its “home” Grand Prix, for example.
Ideally, one might want to show several alternative advertisements during the same race, especially for the minor teams that are unable to attract the “high value” sponsors. However, current application methods require physical contact for a significant time. In a Formula 1 Grand Prix under 2018 rules, cars stop in the pits to change tyres once or twice a race, typically for a few seconds at a time, so no graphic changes are possible—even a few more seconds stopped to replace damaged bodywork can be enough to ruin a driver's chances in a race, so extra time to change graphics would not be possible.
Nevertheless, if it were to be possible to sell advertising in blocks of a few laps, rather than a few races, then the overall value of the advertising space would rise. The economics of advertising (in cases where changes are simple and low cost) almost always shows that for example a dozen five minute slots competed over by multiple advertisers are more valuable than a single slot one hour long that fewer could afford anyway.
Similar considerations apply to the sport of motorcycle racing, in particular for track racing formulas such as MotoGP and Superbike racing. Motorcycles designed for these races have significant areas of curved cowlings and other bodywork, on which is displayed team logos, sponsors' branding, advertisements, rider identification and so forth, in a similar manner to racing cars. These cowlings, etc., are normally made from sheets of carbon fibre composites, similar to formula car bodywork. The problems and opportunities set out above for racing cars are thus equally applicable to racing motor cycles, with the added issue that the area of bodywork on a racing motorcycle being significantly less than on a racing car, so advertising space is at a premium.
Since the rider of a racing motorcycle is far more exposed to view than the driver of a racing car, the rider's protective gear, especially his or her protective bodysuit, the “leathers”, has also become a prominent site for advertising and other graphics. It would thus be just as useful if any method and equipment suitable for improved display of advertising material on racing cars and racing motorcycles could also be applied to a rider's or even a driver's protective clothing and other gear.
It is hence an object of the present invention to provide apparatus for displaying such graphics on bodywork of a vehicle, such as a racing car or a racing motorcycle, and/or on the protective gear of a driver/rider, that obviates the above disadvantages of existing approaches and allows graphics to be changed responsively, rapidly, effectively, cheaply, and without risking the integrity of the bodywork panels at every change. It is also an object of the present invention to provide a method for manufacturing such apparatus. It is a further aspect of the present invention to provide an improved method of arranging the sale and presentation of advertising space on a vehicle, using such apparatus.

In a preferred embodiment, the bodywork element has a plurality of apertures formed therein, each aperture being filled by a corresponding inset panel and having a respective display screen means mounted to the inner face of each inset panel.

Embodiments of the present invention will now be described more particularly and by way of example, in which:
Referring now to the Figures and to
In the present invention, as shown in
When the bodywork panel 13 is subsequently painted in the team or sponsor colours, the paint finish can be extended over the join between the bodywork panel 13 itself and the optically clear panel 16 and feathered inwardly over a marginal region of the optically clear panel 16. This is partly to conceal the joint between the bodywork panel 13 and the optically clear panel 16, both visually and on a microscopic physical scale to maintain aerodynamics smoothness (a further benefit is described below).
Such e-paper flexible display screens 17 can nowadays be made to display colours, as well as the original black and white displays to simulate ink on paper. When images are displayed on the flexible display screen 17 (see below), a background to the images can be made substantially the same colour as the paint finish of the bodywork panel 13, and in combination with the feathered edge to the paint finish around the margin of the optically clear panel 16 (described above), this should make the optically clear panel 16 visually blend seamlessly into the bodywork panel 13, making it appear as if the displayed images were displayed on the surface of the bodywork panel 13.
NB: It is considered beneficial to use reflective display screens 17 in this invention because it allows an image to be displayed at the same brightness level as the surrounding bodywork in all lighting conditions (including the artificial lighting experienced in night racing, as at some Grands Prix). Thus, the image can more readily be made to simulate a painted design, while remaining controllably changeable as desired.
An alternative approach is for the paint finish to be extended over the join between the bodywork panel 13 and the optically clear panel 16, but for a shape of the inner edge of the paint finish not to correspond to a shape of the outer edge of the optically clear panel 16 or to a shape of an outer edge of the display screen 17 beneath the optically clear panel 16. (Typically, the aperture 14, the optically clear panel 16 and the display screen 17 would all be generally rectangular). Thus, the join is camouflaged and the shapes of the optically clear panel 16 and display screen 17 are obscured.
This allows the creation of an illusion of a standalone painted graphic on a background having a colour contrasting with a remainder of the bodywork. (For example, in the 2018 version of the traditionally all-over red Ferrari livery, there is a trapezoidal or “keystone” shaped white area on the nose that acts as a contrasting background for the car number.) A similar shape for an inner margin of the paint finish of a bodywork panel of the present invention would create a “frame”, concealing the rectangular shape of the optically clear panel and the display screen, distracting the viewer's eye from their true shape, and allowing the display of images on a contrasting background of specified shape or on a background of the same colour blending into the overall bodywork paint finish.
The images displayed on the flexible display screen 17 are controlled via a display controller 25, here shown schematically, which is linked by radio to a remote server, located adjacent the racing track, for example in the “pits”. This allows transmission of instructions, via the display controller 25, to change the images shown on the flexible display screen 17 as desired.
In this second embodiment, a flexible reflective display screen 17, such as e-paper, is mounted to an interior surface of the central portion of the optically clear panel 16, by means of a layer of optically clear adhesive 18, very much as in the first embodiment (see above and
This arrangement, like that shown in
In this arrangement, the flexible display screen 17 can readily be removed from the particular bodywork panel 13, either to be replaced if it has become defective or needs to be upgraded, or to allow it to be transferred to a different bodywork panel 13, perhaps having different aerodynamic curvature.
Multiple display screens 17 can be fitted into the same bodywork panel 13, and/or multiple bodywork panels 13 of the car 1 can be fitted with a display screen 17. While each such display screen 17 may be connected to its own individual display controller 25, it would also be possible to have a single display controller 25 controlling multiple display screens 17. The exact balance probably depends on the weight of the display controllers 17 and the weight and complexity of the wiring loom needed if multiple display screens 17 were operatively connected to a small number of display controllers 25.
In a simpler embodiment of the invention (not illustrated), the display controller 25 would not be connected to a remote server, but instead would be set up before a race, pre-programmed with a sequence of images to be shown for specified periods of time. This would not be as responsive as the main embodiments, above, with control in real time from a remote server. However, in less “high-tech” venues than the typical Grand Prix race track, this simpler version of the system might be more practicable.
Each of the arrangements shown in
The images displayed and changed using the arrangements described about can be simple logos or more complicated images including text, although they will mainly be viewed at a distance and on a fast-moving vehicle, so the level of detail that is worthwhile may be limited. Similarly, moving images would technically be possible, but their usefulness would depend on how far movement of the image could be discerned by a viewer.
As a general rule, the images will be generated so that they have a background to the logo, text, etc, which corresponds in colour to the paint finish of the respective bodywork panel. Thus, the logo, text, etc will appear to be applied over a continuous background extending over the whole bodywork element. As noted above, the paint finish of the bodywork panel is feathered inwardly around the margin of the inset panel, further concealing the edges of the aperture, the inset panel and the display screen, and further enhancing the illusion that the inset panel and display screen are a continuous part of the bodywork element.
The scale of the right to display an advertisement on a display screen on a car could be structured in several different ways. Advertising space could for example be sold for fixed 10 minute or 20 minute slots during the standard 2 hour maximum duration of a Grand Prix race. The start and the finish of the race are most likely to draw attention, especially for TV viewers, and so slots at these times might have a higher cost, or might be of shorter duration for the same cost. A further approach would be to sell a particular display location for the entire race, but only as a default, with another advertiser being able to substitute its own advertisement for a selected period if it paid a higher rate. In versions of the technology where the advertisement to be shown is controllable from a remote server, a live auction of time slots and locations on the car could be carried out during the race. A variation of this would have the current highest bidder's advertisement shown, until such a point that its bid was beaten.
There would be other desirable stages of the race for showing advertisements. Currently, Formula 1 rules require cars to make at least one pit stop during the race, during which the car will be stationary for several seconds, and TV camera angles are already set-up. Thus, some advertising spaces can be guaranteed good visibility during a pit stop. Either an operation monitoring the race could use the remote server system to switch to the advertisement that had been booked for pit stops at the appropriate time, or an external trigger could be used. (For pit stops, there are electronic arrangements at the entry and exit of the pit lane, used to regulate speeds in the pit lane for safety's sake—this could be used to trigger an-on-board display controller to switch to a particular advertisement from entry into the pit lane until the car re-enters the track). Periods when the race cars are not at maximum speed, such as when a safety car is out or when the race cars are operating under the “virtual safety car” system, could also be sold at premium rates, because of the greater visibility of the advertisements on a slow-moving vehicle. Again, this could be controlled by an operator via the remote server, or the signals used to indicate e.g. virtual safety car conditions could be used to trigger on-board display controllers to show different advertisements.
If desired, mathematical algorithms could be programmed into the remote server and/or the on-board display controller(s) to produce changes of advertisement according to a more complex set of rules, or perhaps combining several of the above control criteria.
The advertisements themselves will need to be approved as suitable before they can be loaded into the remote server or the on-board display controllers. Initially, this would be carried out by human staff, although in time, computer programs or artificial intelligence systems could automate this step.
As mentioned above, the display screens could also be used to display vehicle data to spectators, although not on the level of detail provided to a race-car's pit crew by existing telemetry systems. Since this would prevent the same screen being used for advertising, however, this approach would probably be limited in use—maybe to brief intervals between advertisements, or only when there is unusual data to be “reported”.
While the invention has been described above in terms of motor car racing, it is equally applicable to motor cycle racing, particularly track racing, such as MotoGP or Superbike racing (Note: MotoGP is a registered trade mark of Dorna Sports SL). Racing motorcycles have a streamlined cowling around the handlebars, and fairings at the front of the body; above the front wheel and in front of the front forks; in front of the rider's legs; around the fuel tank; and a small fairing at the tail. These are all typically made from sheet carbon fibre composites, similar to those used for motor racing cars.
The display of advertising and sponsorship are just as important to motorcycle racing as they are to motor car racing. As a result, the display panel arrangements described above for installation into the bodywork of racing cars could be incorporated into the cowlings and other bodywork of racing motorcycles, with the same features and benefits.
There is however, a small drawback, in that the overall surface area of a motorcycle available for display of advertising and sponsorship material in this way is quite small, relative to a racing car. Formula 1 bodywork almost totally encloses the car's driver, and a NASCAR driver is entirely within the car's body, while a motorcycle rider has much of his or her body fully or partially outside the bodywork of the motorcycle, effectively forming part of the aerodynamic surface of the motorcycle when crouched down at speed. Thus, the available space on motorcycles for the display panels as described for racing cars is not high.
Currently, this lack of space on the motorcycle itself is made up for by applying a great deal of sponsorship and advertising material to the rider him- or herself. Racing motorcyclists wear suits of protective clothing, which customarily bear copious amounts of this material on any surface that will be visible to the spectator, either in the normal crouching racing stance or when sitting up on the motorcycle—the classic winner's pose, for example, being a perfect photographic shot to display logos emblazoned across the rider's chest that would be hidden during the race.
This protective clothing is referred to as “leathers”, and much of it is indeed still made from leather. It currently consists of boots, gloves and a one-piece full body suit, an example of which is shown in
The leathers 30 are mainly made up of shaped panels 31 of leather, stitched together. The leathers 30 must allow the rider freely to change position and balance on the motorcycle, while providing protection if the rider comes off the motorcycle, potentially sliding and scraping at great speed across the track surface, or tumbling and rolling across the track and surrounds, depending on the exact circumstances of their departure from the motorcycle. Leathers 30 are hence constructed as a compromise between protective strength, toughness and stiffness on one hand, and comfort and flexibility on the other. At the professional level, leathers 30 are individually fitted to the rider, both for comfort and for aerodynamics.
Current advertising material is incorporated into the leathers permanently, a change of advertiser requiring the complete replacement of the leathers by a set with the new advertiser's graphics applied. This is time consuming and inconvenient. Advertising material still cannot be changed during a race, as there is nothing like enough time at any stage for the rider to change into a fresh set of leathers.
As shown in
Racing leathers 30 have one further feature, a rigid aerodynamic hump 39, located on the rider's back, below the neck and extending from the shoulder blades, down the back, partway to the waist. When the rider is in the racing position, crouched over the motorcycle with his or her body almost horizontal and head held right back to see forwards, the hump 39 meets the back of the rider's helmet, forming an almost continuous aerodynamic fairing behind the helmet and avoiding the turbulence that would otherwise form behind a rounded helmet.
This construction allows the incorporation of a display panel system, similar to that described above for racing car and motorcycle bodywork, into a modified set of motorcycle racing leathers 40, shown in
In place of the rigid optically clear panels 16 used in the bodywork embodiments of the present invention, the flexible display screen 17 can be mounted to one side of a sheet of optically-clear flexible plastics 42, using an optically-clear adhesive 18, as in the system of
It would also be possible to cut an aperture 14 into leather panels 31 of leathers 30, and to insert the optically-clear flexible plastics sheet 42 from within to form a window, with the flexible display screen 17 being mounted to the inside of this window with the optically-clear adhesive 18.
In general, either or both of these options would preferably be used on the portions of the leathers 30 made from stiff leather panels 31, but where some degree of flexibility is expected.
However, on the aerodynamic hump 39, one could use a variant of the display panels shown above incorporated into vehicle bodywork, since the aerodynamic hump 39 is large, substantially rigid and prominent in use during racing. Here, it would be straightforward to incorporate a suitably-profiled optically clear panel 16 into the rigid aerodynamic hump, with the flexible display panel 17 being mounted to its inner face, much as for any of the bodywork-mounted variants described above (see
The interior of the aerodynamic hump 39 is available to hold the display controller 25 and any other electronics and communication equipment that may be required. Indeed, the aerodynamic hump 39 may conveniently be used to hold the display controller 25, etc, for any of the display screen arrangements incorporated into the modified leathers 40, described above.
Thus, suitable display panels can be incorporated in various places on the modified leathers 40, the type of panel depending on the local flexibility needed, and these display panels can be used to display any of the logos, brands, sponsor identification or more factual data that has been described above as being displayed on racing car or motorcycle bodywork.
In the arrangement of
Thus, in both arrangements, a display screen 17 can rapidly be replaced if necessary, or it can be inserted at the last minute to reduce the risk of damage. They also allow removal of the display screens 17 for cleaning of the leathers 40. It is currently envisaged that these arrangements allowing selective insertion and removal of display screens 17 from the leathers 40 would be particularly suitable for use mounted to the more flexible leather panels 31 of the suit as a whole.
