The large-area display device or transparent media facade has at least one transparent element, wherein the transparent element comprises at least one transparent substrate and at least on a part of the transparent substrate, lighting means are mounted.

Out DD 293 595 A5 For example, a method of making conductive polymers is known. For their preparation, iodine is mixed with an anhydrous polymer-bound nitrogen donor compound. This results in a polymer plastic, which is characterized by a high mechanical stability and therefore can be used as a non-metallic, electrically conductive polymeric material.

Out DE 10 2012 111 937 A1 For example, an electrically conductive polymer composition having a good film-forming property is known. The electroconductive polymer composition contains an electroconductive polymer doped with a dopant, a water-soluble polymer resin and an organic solvent.

From 102 04 257 A1 discloses a housing for a device of consumer electronics is known. In this case, the required connection lines without problems to the housing or the device of consumer electronics can be connected by the lines are arranged directly in or on the housing of the device, without these being immediately recognizable as such. For this purpose, the consumer electronics device has a transparent or opaque housing, on which the electrically conductive components are arranged. The electrically conductive components in / on the housing are made of indium tin oxide or are partially transparent or consist of a thin metal layer or are design elements at least of parts of the housing. The electrically conductive components are located in the interior of the housing or the housing is formed at least in the region of the electrically conductive components as an insulator and the electrically conductive components are parallel to each other.

There is a Flächenheiztextil present, which is disposed on a side facing away from the honeycomb core at least on one of the cover layers and at least one decorative layer which covers the Flächenheiztextil and forms a surface of the interior trim component.

In or on such plastic components for use in a motor vehicle, electrical components, such as sensors, lighting means or input means for inputting operating commands for controlling a component in the motor vehicle are often arranged or arranged intended. These electrical components require an electrical power supply and possibly also control lines. So far, corresponding electrical lines have to be laid along the components for this purpose and to be electrically connected to the electrical components during installation.

The disadvantage here is that cables for the power supply for the electrical components and the possibly existing control lines are connected before installation in the motor vehicle, these cables are to be laid along the component and then connected to the electrical components. This is very time consuming and costly. When designing and developing the component, care should be taken to ensure that the cables are largely invisible to a user after installation, while not compromising the function and shape of the component.

The fact that the fibers have different dimensions, these go in the manufacture of the component from the plastic with the mixed fibers in addition mechanical connections by the fibers get caught with each other. Due to the linear polymers, the fibers are incorporated directly into the molecular chains of the plastic which form when the plastic cools.

The slat 1-1 consists of two different thermoplastic materials, the lamella 1-1 made by a 2-K injection molding process.

The first thermoplastic material essentially forms the shape of the lamella 1-1 out. This area 1-4 The lamella is non-conductive and consists of thermoplastic material, which is added to its reinforcement and to influence the mechanical properties of the plastic with additives. There are also two more areas 1-2 and 1-3 in the lamella 1-1 introduced, which are electrically conductive and in 1 quasi form a conductor, the lamella 1-1 runs in the longitudinal direction, but approximately in the middle 1-9 the slat 1-1 is interrupted. The two electrically conductive areas 1-2 . 1-3 the slat 1-1 consist of thermoplastic material which is electrically conductive by the addition of additives and / or additives.

It has proved in a particular embodiment of the invention to be particularly advantageous, this thermoplastic material, which preferably consists of polyamide, with fibers and / or fiber sections made of metal, in order to provide an electrically conductive structure in the lamella 1-1 contribute.

Around the slat 1-1 to supply with electricity, are from the journals 1-7 . 1-8 protruding wire sections 1-5 . 1-6 or supernatants of the electrically conductive thermoplastic provided laterally over the bearing pin 1-7 . 1-8 protrude and connect with electrical contact points, so that the two conductive areas 1-2 and 1-3 electrical energy can be supplied or discharged.

In the area of the middle 1-9 the slat 1-1 are contact surfaces 1-10 . 1-11 educated. About these contact surfaces 1-10 . 1-11 is an electrical consumer, in the specific embodiment according to 1 in the form of an LED 1-12 arranged.

The slat 1-1 exists in the non-electrically conductive area 1-4 , as already described, made of thermoplastic material, wherein introduced into the thermoplastic fibers of different types and lengths and mixed with the corresponding thermoplastic resin granules. However, additives may additionally or alternatively be admixed with the thermoplastic.

So that the lamella 1-1 is designed to be light and yet stable, it is provided that the lamella 1-1 is made of thermoplastic material which is mixed with fibers and / or additives, wherein the fibers and / or additives are selected such that the lamella 1-1 after the production of which has a modulus of elasticity of at least 42,000 MPa. However, it has proven to be particularly effective to select the fibers and / or additives such that the lamella 1-1 has a modulus of elasticity of at least 36,000 MPa after its production; it is even intended, the lamella 1-1 to give a Young's modulus of 48,000 MPa.

The slat 1-1 is designed to have a modulus of elasticity of at least 42,000 MPa in the longitudinal direction and / or in the transverse direction and / or in torsional twisting. However, it has proven to be particularly effective to select the fibers and / or additives such that the lamella 1-1 in the longitudinal direction and / or in the transverse direction and / or in torsional torsions has a modulus of elasticity of at least 36,000 MPa after their preparation.

A slat 1-1 with a corresponding modulus of elasticity of at least 42,000 MPa is achieved by adding fibers and / or additives of predefined type and amount to the thermoplastic material. These fibers and / or additives will be discussed in more detail below.

The slat 1-1 consists of the two plastics, which are the two conductive areas 1-2 . 1-3 and the non-conductive area 1-4 form. At the contact surfaces of the two conductive areas 1-2 . 1-3 and the non-conductive area 1-4 an interface forms, in which the two plastics of the conductive areas 1-2 . 1-3 and the non-conductive area 1-4 interlink.

In 2 is a section through a part of the lamella 1-1 from 1 shown; 2 shows a partial section of the section in the region of the contact surface of the two plastics 2-1 . 2-2 , It is the area shown enlarged schematically, in which the two plastics 2-1 and 2-2 the slat 2-3 touch. Both plastics 2-1 . 2-2 are made of thermoplastic material with fibers 2-4 . 2-5 and / or additives is mixed.

The plastic 2-1 are fibers 2-4 , which are designed as preferably "short fibers" admixed, which consist of electrically conductive material, such as metal. The plastic 2-2 are fibers 2-5 admixed as "long fibers" and made of non-conductive material such as carbon fibers, carbon fiber sections, glass fibers, glass fiber sections, plastic fibers or sections of plastic fibers.

In a particular embodiment of the invention, it is provided that in the case of the use of fibers made of plastic or sections of fibers made of plastic, this plastic, from which the fibers or fiber sections are made, has a much higher melting point than the plastic to which they are added.

During the 2-K injection molding process, with which the lamella 3 is produced, forms between the two plastics 2-1 and 2-2 an interface or a boundary layer 2-6 out. At this boundary layer 2-6 there is a toothing between the fibers 2-4 and 2-5 of the two plastics 2-1 and 2-2 , At the time when the second plastic 2-2 at first plastic 2-1 is applied, is the first plastic 2-1 not yet or not cured and / or by the hot and liquid plastic of the second plastic 2-2 melted. It is done so sticking the Molecular chains of the first and second plastic 2-1 . 2-2 in the boundary layer 2-6 and in addition the fibers get caught up 2-4 . 2-5 in the boundary layer 2-6 ,

When producing the lamella 2-3 The plastic used is preferably linear and / or partially aromatic polyamides and mixtures thereof. Short names are eg PA, PAA, PPA. Polyamides are polymers with regularly repeating amide bonds along the main chain. The amide group can be considered as the condensation product of a carboxylic acid and an amine. The resulting bond is an amide bond, which is hydrolytically cleavable again.

Polyamides are often used as construction tools because of their excellent strength and toughness. Good chemical resistance exists over organic solvents. However, there is still the possibility that polyamides are attacked by acids or oxidizing chemicals. In order to influence the properties of the polyamides, that is to say the plastic polyamides, further in the direction of the desired housing stability, fibers and / or further constituents are admixed with the polyamides.

With the fibers 2-4 . 2-5 they are fibers with the same and / or different lengths, as already described. The fibers 2-4 . 2-5 prove in the specific embodiment 2 different lengths, diameters or thicknesses. By choosing the fibers 2-4 . 2-5 , their dimensions and / or the material of the fibers 2-4 . 2-5 The polyamide, to which these fibers are added, can be changed in terms of both physical and chemical properties. The physical properties of the plastic, in particular of the polyamide, can be achieved by admixing the aforementioned fibers 2-4 . 2-5 influence and change and in particular one of the two plastics can be made electrically conductive. In this way, simple and structural properties of the plastic can be changed and adapted to the required specifications. It can in the manner described a power supply line in the lamella 2-3 be introduced.

In plastics technology, an important characteristic of the mechanical property of a plastic is the so-called modulus of elasticity or, for short, the modulus of elasticity, also referred to as Young's modulus - named after the physicist Thomas Young. The modulus of elasticity is a material characteristic value from material technology that describes the relationship between stress and strain in the deformation of a solid body with linear-elastic behavior. The value of the modulus of elasticity is greater, the more resistance a material opposes to its deformation. A material with a high modulus of elasticity is stiff. A low modulus material is compliant. The modulus of elasticity is the proportionality constant in Hooke's law. For crystalline materials, the modulus of elasticity is always directional. Once a material has a crystallographic texture, the modulus of elasticity is anisotropic.

The slat 2-3 is chosen so that by the admixture of fibers 2-4 . 2-5 or alternatively additives the slat produced 2-3 has a modulus of elasticity or modulus of at least 42,000 MPa. This is achieved by giving the thermoplastic the fibers 2-4 . 2-5 and / or other additives, in the fibers 2-4 . 2-5 Fibers with a predefined fiber length and / or type of material, are admixed. The mixture of the plastic and the proportion of fibers 2-4 . 2-5 are chosen so that a lamella made from this mixture 2-3 In addition, in addition to the functionality of integrating an electrically conductive area 2-1 , has a modulus of elasticity of at least 42,000 MPa.

In 3 is a perspective view of a Luftausströmers shown.

Over the two air supply openings 3-3 the air vent is supplied with an air flow in the housing 3-1 over slats that in 3 are not shown, is influenced in its orientation. In front of the air outlet openings 3-2 is a blind 3-4 arranged on the front of the housing 3-1 attachable and with this force and form-fitting connectable.

The housing 3-1 consists of two different thermoplastic materials. The housing 3-1 is therefore produced by means of a 2-K injection molding process. The first thermoplastic material forms the housing 3-1 and is electrically non-conductive. It is thermoplastic material used, which is added to its reinforcement and to influence the mechanical properties of the plastic with additives.

In the case 3-1 or on the housing 3-1 are several areas 3-5 . 3-6 . 3-7 . 3-8 intended. These areas 3-5 . 3-6 . 3-7 . 3-8 consist of electrically conductive thermoplastic and form rectilinear areas that remind of tracks. Each one of these areas 3-5 . 3-6 . 3-7 . 3-8 has two contact surfaces each on, in 3 only one contact surface each 3-9 . 3-10 . 3-11 . 3-12 is visible. The areas 3-5 . 3-6 . 3-7 . 3-8 Each form quasi a conductor, which is the housing 3-1 at least partially circulates or passes through.

The electrically conductive areas 3-5 . 3-6 . 3-7 . 3-8 are formed in pairs and form a power supply and current drain to an electrical consumer, in the housing 3-1 or on the case 3-1 is arranged. Such an electrical load is eg a servomotor for adjusting in the housing 3-1 arranged slats or one or more lighting units in or on the housing 3-1 , In 3 the electrical consumers are not shown.

In an advantageous embodiment of the invention, it has proved to be particularly advantageous for the housing 3-1 and its non-conductive plastic to use a polyamide having a glass fiber content of 30 to 50% for mechanical reinforcement and for the electrically conductive areas 3-5 to 3-8 as well as the contact points 3-9 to 3-12 to use an electrically conductive plastic and there to provide a glass fiber content of 50% for mechanical reinforcement.

The thermoplastic of the housing 3-1 consists, as already described, of thermoplastic material, the fibers of different types and lengths are supplied and mixed with the corresponding thermoplastic resin granules. However, additives may additionally or alternatively be admixed with the thermoplastic.

So the case 3-1 is designed to be light and yet stable, it is provided that the thermoplastic used is mixed with fibers and / or additives, wherein the fibers and / or additives are selected such that the housing 3-1 after its preparation has a modulus of elasticity of at least 42,000 MPa. However, it has proved to be particularly effective to select the fibers and / or additives such that the housing has a modulus of elasticity of at least 36,000 MPa after its production; it is even intended to the housing 3-1 to give a Young's modulus of 48,000 MPa. The modulus of elasticity of the housing 3-1 is present in the longitudinal direction and / or in the transverse direction and / or torsional twists.

In 4 is the perspective view of the housing 3-1 of the air vent according to 3 shown, wherein on the housing 3-1 an electrical connection module is arranged. The electrical connection module 3-13 owns the contact points 3-9 to 3-12 of the housing 3-1 coordinated mating contact points 3-14 to 3-17 , The connection module 3-13 has a plug 3-18 , In the plug 3-18 a counterpart can be inserted, which is connected to a power grid and the mating contact points 3-14 to 3-17 over conductor tracks 3-19 to 3-22 to the plug 3-19 connects.

The connection module 3-13 is in its simplest form of embodiment, a circuit board with the mating contact points 3-14 to 3-17 , The mating contact points 3-14 to 3-17 be with the contact points 3-9 to 3-12 electrically connected by being welded or caulked together.
