Benefits of technology
[0012]It is an object of the invention that a textile surface structure will realize electroluminescent light sources of large dimensions and activatable displays with high efficiency and simple production. Due to its technologically simple manageability, the textile surface structure can be integrated into such consumer goods as textile materials for interior decoration, protective work clothes, advertising banners or other such similar commodities.
[0025]By design and arrangement of the conductive threads as well as the connection elements, it would be possible to create a display matrix having pixels able to be activated individually or by group.
[0034]The surface structure produced by the method according to the invention can be readily sewn directly onto a textile base material or be mass-produced like conventional fabrics. The actual textile product, e.g. an item of clothing, interior linings for automobiles, a technical textile, etc., forms a unit together with the electroluminescent light source. The structure created is more mechanically resilient and, as previously mentioned, substantially more flexible than the structures known to date from films or so-called electroluminescent fibers (ELF) with diameters in the range of >2 mm.
Problems solved by technology
The flexibility of such electroluminescent arrangements is limited and mandates that the outer surrounding electrode is to be configured of a transparent material.
It has been shown, however, that the output of visible light is extremely small given such an embodiment of a textile surface structure having an inorganic electroluminescent layer.
This is due to the coating material penetrating into the gaps between the fibers to thereby result in attenuation by shadow effect.
If one were to now apply greater quantities of electroluminescent material based on the prior art, this would result in the desired flexibility and typical haptics of a textile structure being lost.

Embodiment Construction
[0044]FIG. 1 sets out from a conductive textile thread having a diameter of ideally 20 μm to 50 μm, with a maximum diameter of 500 μm, leading to outer electrodes 1. The coating is identified here by reference numeral 7 and the thread by reference numeral 8.
[0045]The electroluminescent textile surface structure according to FIG. 2 assumes alternatingly introduced conductive 1 and non-conductive 2 weft threads. Outer conductive warp threads 3 are threaded through for laminar contact.
[0046]The comb-like electrode structure is achieved by alternating and excluding left and right side flotation of the conductive weft threads in flotation region 4.
[0047]The basic representation according to FIG. 3 clearly shows how producing a multi-layer fabric, parts of which exhibit electrically conductive weft and warp threads insulated from one another by the fabric construction, provides for crossings of wefts and warps which are individually selectable and thus generate as it were points of light....

Abstract
The invention relates to a surface textile structure comprising an arrangement of a plurality of conductive threads or threads exhibiting conductive properties. Insulating sections are arranged between the conductive threads or insulating threads are incorporated into the structure. The structure also comprises an inorganic electroluminescent material and electric connection elements. According to the invention, the electroluminescent material is incorporated into intermediate areas of the structure or is embodied inside the structure in the form of coated threads. The structure is also provided with a coating which is also selective made of a fluorescent material and / or optical brightening agents. The overall arrangement comprises a transparent, elastic, covering protective layer.
