• the present invention relates to an insulating glass pane and an arrangement of several insulating glass panes. Furthermore, the invention relates to a method for displaying a static or dynamic image by means of an arrangement of several insulating glass panes. Furthermore, the present invention relates to a building facade with an insulating glass pane arrangement.
• Insulating glass panes are well known. These usually comprise two glass panes, which are arranged by means of spacers plane-parallel to each other and form between them an insulating space, which is usually filled with a noble gas and gas-tight, in particular closed diffusion-tight. Such insulating glass panes are used in windows, but also for the manufacture of particular large-scale glass facades of buildings such. B. office buildings used. The insulating glass insulates the corresponding building to the outside and at the same time allows - depending on the coating of the insulating glass - the view through the respective insulating glass pane and the incidence of daylight through the insulating glass pane.
• Facades are usually used very large display devices for displaying texts, images, videos and the like. These are usually mounted as an opaque LED (light emitting diode) wall on the facade.
• LED light emitting diode

• such a display due to its very large depth, which can be in the range of 40 cm, massively changes the appearance of a facade.
• the invention is therefore based on the object for at least one of the disadvantages described to propose an improvement or at least one alternative, in particular to provide an improved or alternative display option for facades or the like.
• an insulating glass pane according to claim 1 is proposed.
• the insulating glass according to the invention thus has two by means of spacers plane-parallel and spaced from each other arranged glass panes, which form between them a gas-tight sealed isolation.
• a plurality of spaced-apart light strips each having a plurality of spaced-apart light-emitting elements are arranged.

In the case of a mirrored insulating glass pane, even with the light strip switched off, this and its structure are barely visible from the mirrored side. It should be added that such insulating glass panes are intended for the use of large facades and anyway an outside viewer sees the facade and thus the insulating glasses usually from a large distance and even then hardly perceives the luminescent strips and their construction or not at all.

• Windows of the first to third floor according to area 11 are provided with vertically arranged insulating glass panes 9 and horizontally arranged insulating glass panes 9a according to an embodiment of the invention. Between the insulating glass panes 9 and 9a parts of the façade such as facade support 10 can be seen. The total of 56 insulating glass panes 9 and 9a thus form an overall display for the illustrated facade 40.
• the insulating glass panes 9 and 9a are arranged in the facade 40 as a regular glazing so basically as a window. It is clear that even from the fact that the first insulating glass panes 9a begin above the ground floor according to area 12, an observer standing in front of the facade must be at a certain minimum distance even to the lowest insulating glass pane 9a and any light strips are hardly visible when switched off ,
• FIG. 4 is shown only by way of example, and in particular in the case of even larger facades in the lower area, it is possible to leave several floors free and to arrange a large display in a significantly higher area.
• FIG. 5 shows the construction of an insulating glass pane, of which only a detail is shown in a sectional representation.

• a circuit board 20 is fixed by means of a partially electrically conductive adhesive.
• the printed circuit board 20 is formed as a continuous printed circuit board and comprises a first and second end control unit 19A and 19B. These end control units 19A and 19B are shown only schematically and also each include a multi-color LED as a light-emitting element.
• the metal rod 21 is electrically conductively connected to the spacer 15.
• the control data is transmitted from an intermediate control unit 17 via data lines 18 to the printed circuit board 20 and from there forwarded successively to the first end control unit 19A and on to the second end control unit 19B.
• FIG. 6 schematically shows a person standing in front of an insulating glass pane according to the invention.
• the view through the insulating glass depends on the distance between two adjacent light strips, based on two adjacent light-emitting elements, which can also be referred to as pixel pitch, the width and the depth of the light strip, if it is simplistically assumed by a rectangular in cross-section light strip, and the distance of the viewer from the insulating glass pane. From these values results a minimum viewing angle ⁇ , above which a view through the insulating glass pane is possible. Accordingly, there is a clearance angle under which can be seen through the disc.
• a disk width results in which it can at least partially see through the disk and which is referred to below as the transparent width.
• the relationships are additionally illustrated in FIG. Here it is assumed that the light strips are arranged vertically.
• a width of 4mm and a depth of 3mm results in a viewing angle ⁇ of 10.7 ° and a clearance angle of 158.5 °.
• a transparency of 80% can be specified. At a distance of 1 m, this results in a see-through width of 10.5 m and at 5m distance of 52.7 m. If the pixel pitch is increased to 40mm, the viewing angle ⁇ is 4.8 ° and the clearance angle is 170.5 °.
• the transparency with vertical view can be specified with 90%. At a distance of 1 m, this results in a see-through width of 23.9 m or at 5m distance of 119.7m.
• a luminescent strip 60 is arranged in the insulating glass pane 62 between a first and a second glass pane 63 and 64.
• Two final control units with LED 61 are shown symbolically.
• the glass panes 63, 64 are kept at a distance by means of the upper and lower spacers 65, 66.
• the upper spacer 65 is T-shaped in cross section and holds the light strip 60 via a first H adapter 67.
• a splint 68, 69 is provided both for the upper spacer 65 and for the light strip 60, it can also eg a screw can be used.
• the light strip is attached by means of a second H-adapter 70.
• the attachment between the second H-adapter 70 and light strip 60 is effected via a split pin 71, whereas the second H-adapter 70 is fixed by a spring 72 and a pin 73 elastically to the lower spacer. Any temperature-related changes in length of the light strip 60 can thus be compensated by the spring 72 without the spring 72 has to carry the weight of the entire light-emitting strip 60.
• FIG. 9 illustrates in a sectional view the structure of a carrier 80 with attached circuit board 83. Any final control units or light-emitting elements are not shown for clarity.
• the carrier 80 consists essentially of a first and second metal bar 81, 82, which are glued together by means of an electrically insulating adhesive 84 and thereby form a solid, in particular torsionally rigid construction.
• the printed circuit board 83 is fixedly connected to the first and second metal rods 81, 82 by means of a partially electrically conductive adhesive 85.
• the distance from the printed circuit board 83 to the first and second metal rods 81 and 82 is so small that in each case an electrically conductive connection is formed.
• an electrically conductive connection does not exist in the adhesive 85 along the printed circuit board 83 and thus also not between the first and second metal rods 81, 82.
• the metal rods 81, 82 can therefore be used as individual galvanically isolated supply lines.
