[0094] FIG. 1 shows, by way of example, various types of utility vehicles with respective utility vehicle structures in a perspective view from the rear side.

[0095] FIG. 2 shows, by way of example, a side sectional view of a display field, in which a multiplicity of LEDs or SMDs 33 are arranged as display pixels on a module 31. On the side on which motifs can be presented by the display field, a display pixel protection 34 is fastened over the display field. The display field is fixed by a display frame 18, which is connected to a display rear wall 29. In addition, display protection elements 36 may be present. The display field can be supplied with data and power via an interface 32, for example via a cable 9 from a data unit 7, which has connections for a data line and a power cable 10. A cooling fan 15 can be installed in the vicinity of the display field for cooling.

[0096] FIG. 3 shows a perspective illustration of the installation of a display unit explained on the basis of FIG. 2 on door or wall panels 19 of a utility vehicle structure.

[0097] FIG. 4 shows a perspective illustration, based on door leaves 2, 3, fixing screws 27 and connecting screws 26 for attaching a display field.

[0098] FIG. 5 additionally shows, in a perspective illustration the attachment of a data unit 7, for example with a computer, and of a power converter 12 to a component of a utility vehicle structure.

[0099] FIG. 6 shows, in a side sectional illustration, an advantageous, vibration-damped attachment of a pixel-technological display field, for example on a side wall 38 or a rear wall 40 of a utility vehicle structure. The display field 5 is encapsulated with respect to the inside of the vehicle structure via a display rear wall 29. On the front side, on which motifs can be presented by the display field, the latter is covered by a display pixel protection 34. The latter is structurally fixed with the screen 44 of the outer frame 18 to the panels 19 of the rear wall 40 or side walls 38 in terms of damping technology. The vibration damping and the tightness of the structure are realized by rubber seals 16 and rubber-bonded metals or shock absorbers 28.

[0100] FIG. 7 shows different embodiments of the attachment of a pixel-technological display field 5 to a cover 38, 39, 40. For example, the cover can have a continuous recess in which the display field 5 is arranged. The display field 5 is covered by a respective protective film 17 on both sides of the cover. The protective films 17 are connected to the cover 38, 39, 40 via material connections 47 (FIG. 7a). In addition, the display field can be encapsulated in an extra display cell 48.

[0101] While in the embodiment of FIG. 7a both protective films 17 are attached to different sides of the cover, FIG. 7b shows an embodiment in which both protective films 17 are attached to the same side of the cover, for example to the outside, by means of the material connections 47 on the cover 38, 39, 40.

[0102] FIG. 7c shows an embodiment in which the recess in the cover is not made continuous, but rather in the manner of a blind hole. A certain layer thickness of the cover thus remains throughout, which means that the cover continues to be sealed. In this case, the display field 5 can either be covered with a protective film 17 on only one side, or, as shown in FIG. 7c, similar to the variant according to FIG. 7b, with a front and a rear protective film 17. The protective films 17 are then in turn connected to the cover 38, 39, 40 via the material connections 47.

[0103] FIG. 7d shows the arrangement of a display field 5 on the outer surface of a cover 38, 39, 40. In this case, the cover does not have to be prepared with a recess. Instead, the display field 5 can simply be placed on the surface of the cover. Here, too, it is advantageous to cover the display field 5 in each case on the front side and the rear side with a protective film 17. The protective films 17 are in turn connected to the cover 38, 39, 40 via material connections 47.
