- the object of the present invention is now to provide an improved display device.
- a display device has at least two display elements and at least one interface.
- the display elements are connected by means of at least one display line to the interface.
- the display lines are designed such that a part of the display device which contains at least one display element can be finally removed from the display device during or after the installation of the display device, without impairing the function of the at least one remaining display element. This ensures that the device can be cut in a completely flexible manner. Even the removal from the functional part of the display device, which contain display elements, is not a problem for the functionality.
- a display device has an embodiment in which the display elements are mounted on the front of the display device and the interface on the rear side. This has the significant advantage that in a finished installation located display devices must be accessible only from the rear to ensure the revisionability. The complete wiring during installation and maintenance can take place in an area which remains hidden to the viewer of the image on the display device according to the invention.
- control logic unit which controls the at least two display elements via the at least one interface.
- This control logic unit thus serves to represent the image part provided for the display device. Accordingly, communication between the control logic unit and the individual display element takes place via the display status of the individual display element.
- the control logic unit exclusively controls the power supply to the individual display elements and thus switches these on and off.
- a qualitative control of the display elements in the context of the present invention is conceivable.
- the provision of a single control logic unit for all provided display elements also facilitates installation. Thus, after the physical installation of the display device, the wiring can be done centrally via the control logic unit.
- the connection between control logic unit, interface and Display elements can then be prepared already in, for example, industrial frame on the assembly line.
- a control logic unit advantageously has at least one power connection and at least one data input.

- control logic unit is physically separated from the display device.
- the control logic unit is connected to the display lines and display elements only via the control terminals.
- the physical separation of the control logic unit from the display device achieves the highest level of flexibility of the display device in terms of free cuttability.
- each interface is provided for each display element, a part can be cut out even in the display device with a plurality of display elements, which is arranged centrally in the display device and contains any number of or few display elements.
- the provision of more than one control logic unit is also conceivable within the scope of the present invention.
- control logic units are also physically separate from the same display device and connected to it only through the control terminals.
- the result is a display device according to the invention which, at least in a part in which the control logic unit is physically separated from the display device, has the highest level of flexibility with regard to the free separability of parts.
- a feature of the unrestricted functionality after disconnecting a part of the display device with at least one display element is the arrangement of the display lines on the display device.
- these display lines extend linearly at least in one direction from the interfaces to the display elements.

This minimizes the costs on the one hand and the space requirement on the other.
- CPU Central Processing Unit
- One way to arrange the control unit is to attach it directly to one of the display devices located in the display system.
- An alternative to this is the separate arrangement to the display device.
- both the other and the other alternative may be the more meaningful variant.
- the arrangement of the control unit on one of the display devices has the advantage that the space requirement of the entire display system is further reduced.
- the arrangement of the control unit separately from the display device has the advantage that even greater flexibility in the design of the display system is possible. Also, in this case, the maintenance of the display system is even easier to design, since the maintenance work, which concern only the control unit, can be performed directly on this, which can be mounted much more accessible.

- a precise addressing possible display device failures can be returned to the failure of individual display elements.
- detailed information about possible faults is available in the control unit.
- the joints between the individual display devices are provided with a joint element.
- This joint element fixes the display devices to each other and at the same time defines a constant distance between these points.
- the joint element serves to level the entire surface of the display system.
- Such a joint element has, for example, a substantially T-shaped cross-section with an additional, centrally arranged transverse bar. Between this transverse line and the upper T-bar, a groove is thus formed on the left and right in each case, into which parts of the two adjacent display devices, in particular the circuit board, can be introduced. The web located between these two grooves defines the fixed joint width.
- an inventive joint element made of flexible plastic for a joint width of in particular 3 mm is designed.
- joint widths such as 1 mm, 2 mm, 4 mm or 5 mm are possible. It is particularly advantageous if the joint element is made substantially watertight. Thus, the back of the display system can be protected by the surface of the individual display devices and sealed sealed joint elements against water.
- the invention relates to a display area consisting of at least two display systems.
- a central unit is provided. see which is connected to the control units of the individual display systems.

This cascade allows on the one hand a central control on the other hand, a high data speed in a variety of display elements to be controlled. Each display element thus provides a pixel for the central unit.
- connection between the central unit and the control unit is preferably carried out by means of fiber optic cable.
- a simple wiring with high speed of data transmission can be made.
- the central unit can control each individual display element of a display device via the control unit and the interface or the control logic unit.

These LEDs can be both pure black and white LEDs for generating a stationary or moving image in grayscale, as well as colored LEDs, in particular RGB LEDs (RGB are the primary colors red green and blue) to represent high-quality color representations on the display device.
- RGB LEDs RGB are the primary colors red green and blue
- the present invention is not limited to the type of the display elements.
- organic LEDs (oLED) can also be used in a display device according to the invention.

- a board layout can be created, which allows an even more flexible cutting of the display device. For example, network structures are possible even allow the cutting out of individual display elements of the display device without affecting the functionality.
- Another advantage is when the board is at least partially thermoplastically deformable even in the installation state, without the display line and the LEDs are affected. In this way, even curved surfaces, such as transitions to door frames or even the inner lining of tunnel-like aisles over the entire surface will be equipped with a display device according to the invention. There is, so to speak, the possibility of an arbitrarily large and freely adaptable, as completely flexible cut-to-size displays.
- predetermined breaking points which are designed for separating individual parts of the display device.
- material weakening to complete materialless areas are conceivable, which at the same time give the installer an indication in which area and in which direction a cutting is possible and in which not.

- the predetermined breaking points are designed for a width of exactly 3 mm. Also, larger or smaller values such as 1 mm, 2 mm, 4 mm, or 5 mm are conceivable, It is only essential that all display devices according to the invention used have the substantially same predetermined breaking point width. This is the only way to ensure that when using a plurality of display devices, there is no misalignment between the individual devices during installation. Such an offset would have the significant disadvantage in displaying the still or moving image that the real displacement of the display devices would be perceived as a pixel offset and thus an unaesthetic shift in the image.
- control logic units are also physically separate from the same display device and connected to it only via the control terminals.
- the result is a display device according to the invention which, at least in a part in which the control logic unit is physically separate from the display device, has the highest level of flexibility with regard to the free separability of parts.
- a feature of the (unrestricted) functionality after separating a part of the display device with at least one display element is the arrangement of the display lines on the display device.
- these display lines extend linearly at least in one direction from the interfaces to the display elements.
- Another embodiment is the star-shaped arrangement of the display lines between the display element and interface.

- Fig. 6 illustrates the fastener 100 in its profile.
- a boom 800 is attached, which has a mounting surface 400.
- the planes spanned by the attachment surface 400 and the support surface 200 together enclose the angle ⁇ .
- Between the clamping surfaces 600 and the support surface 200 of the angle ß is included. Together, these two angles add up to a total of 90 °.
- the mounting surface 400 can be brought into a position parallel to the support surface 200.
- FIG. 7 shows a further exemplary embodiment of the present invention, wherein the fastening means 100 shown there shows a profile which is substantially complementary to the profile according to FIG. 6. Also, the embodiment shown here shows two clamping surfaces 600, which together with the support surface 200 include the angle ß.
- the boom 800 also has a mounting surface 400, which together with the support surface 200 include the angle a. In contrast to the embodiment according to FIG. 6, the mounting direction is changed here. While a fastener 100 of FIG. 6 can be pushed from behind on the scaffold-like holder, this process happens in the embodiment of FIG. 7 from the front.
- FIGS. 8, 9 and 10 show three different exemplary embodiments for different values of the parameter y in the fastening situation.
- y is set larger than 0, whereby the attachment surface 400 stands forward (upward in the drawing).
- y is chosen to be 0, so that the fastening surface 400 just comes to rest with the upper edges of the clamping surfaces 6.
- Fig. 10 shows an embodiment with a negative value for y.
- the mounting surface 400 is backward (in the drawing down) back.
- Fig. 11 shows a fastener 100 according to the invention with a web 140 which is attached to the boom. By means of this web 140, the user of the fastener 100 can bend the clamping surfaces 600 apart and thus guide the fastener 100 around the frame-like mount.
- the width of the web 140 decreases at a distance from the clamping surfaces 600, since the burden of the boom 800 decreases to the same extent. In this way, material can be saved.
- an extension 110 can be attached.
- This extension 110 has a second attachment surface 120 which lies substantially in the same plane as the first attachment surface 400.
- two mounting surfaces 400 and 120 are available to fix the planar element.
- FIG. 13 shows an exemplary embodiment of an extension 110.
- the second attachment surface 120 is in this case made along the elongated hole over the entire extension 110. This further increases the flexibility.
- the extension 110 may be attached to the attachment means and is freely rotatable about the attachment surface 400 on the extension 800 prior to fixation and thus adaptable to the real installation situation.
- FIGS. 14a to 14f each show different embodiments of the fastening means.
- a fastening means with only one arm is shown.
- FIGS. 14b to 14d fastening means with two arms are shown.
- Fig. 14e there is shown a fastener with three beams and in Fig. 14f a fastener with four beams is shown.
- the clamping surfaces 600 are inclined inward toward the mounting surface 200 and enclose an angle ⁇ smaller than 90 °.
- the fastener 100 may be attached to a scaffold-like mount.
- Each of the fastening means shown here has 4 arms 800 each with a mounting surface 400.
- the boom can be used to bend apart the clamping surfaces and to facilitate the attachment of the fastener to the scaffold-like support. A separate plant It is no longer necessary to open the clamping surfaces in this case. This facilitates and accelerates the use of the fastening means according to the invention.
- the geometry of the entire fastening means is designed such that the force required to open the clamping surfaces is smaller than the force required for the plastic deformation of the fastening means. This ensures that even when attaching the fastening means no plastic deformation takes place, which could adversely affect the angular relationships of the individual levels to each other.
- the angle a is adapted to the fastening situation such that in the fastened state the planes defined by the fastening surface and the mounting surface are substantially parallel to one another.
- an attachment of the substantially planar elements is ensured in a manner that a flat attachment of the substantially planar elements is ensured by the bias of the fastening means in the attachment situation.
- angle ⁇ between the plane defined by the clamping surface and the support surface planes is less than 90 °.
- This angle ⁇ represents the bias of the clamping surfaces. It correlates directly with the angle a.
- the angle sum of a and ß is substantially equal to 90 °.
- the clamping surfaces are bent in the fastening situation to an angle ß equal to 90 °, whereby the angle ⁇ drops to 0 ° and thus the mounting surface comes to lie substantially parallel to the support surface.
- the difference y can be chosen equal to 0, smaller than 0 or greater than 0.
- the difference y makes it possible to bridge a flexible distance between the frame-like support and the substantially flat surface to be fastened. If one selects a value greater than 0 for y, the boom stands forward from the scaffold-like mount, while it stands back in the case of a choice for y smaller than 0. When y is 0, the substantially flat element can come to rest in a plane with the scaffold-like holder.
- An inventive fastening means is advantageously made of plastic.
- thermoplastic materials are conceivable, wherein the fastening means can be produced in a simple manner by injection molding.
- it is additionally useful to provide at least one screw, which holds the fastening means in place in addition to the clamping.
- an extension for the boom which is formed separately from the boom.
- This extension has at least a second attachment surface.
- This second attachment surface is parallel to the first attachment surface of the cantilever. It is particularly advantageous if, despite the arrangement of the separate extension on the extension arm, the first attachment surface remains usable. In this way, a single boom at least two mounting surfaces and thus two attachment points can be used. This guarantees a simple and secure fixation of the substantially flat element to the scaffold-like holder.
- the difference y of the distance z of the two spanned by the mounting surface 400 and the support surface 200, mutually parallel planes and the width x of the associated clamping surface 600 may be substantially greater than zero.
- the fastening means 100 may be made of a plastic, in particular of a thermoplastic material.
- At least one securing means can secure the fastening means 100 against slipping in the fastening state.
- two cantilevers 800 preferably three cantilevers 800 and more preferably four cantilevers 800 may be formed with at least partially, preferably in pairs, different lengths.
- an extension 110 can be provided for at least one boom 800.
- the extension 110 has at least one second attachment surface 120, which is parallel to the first attachment surface 400.
- the first attachment surface 400 can remain usable.
- the difference y of the distance z between the two planes parallel to each other and spanned by the attachment surface (400) and the support surface (200) and the width x of the associated clamping surface (600) is substantially equal to O.
- the difference y of the distance z of the two planes parallel to one another and the width x of the associated clamping surface (600) spanned by the fastening surface (400) and the mounting surface (200) is substantially smaller than O.
