<p>A tile meant for the building industry, especially as an informational and advertising tool, consists of at least two layers, one of these layers at the front is transparent and at least one transparent layer and/or layer adjacent to it has at least one graphic element placed on the surface adjacent to the next layer. The improved visibility of the information placed on the tile is achieved by light emitting diodes arranged on the side of the trasnparent layer. The transparent layer is preferably made of glass, the non-transparent layer is preferably made of ceramics. Individual layers are connected by a transparent binding material. The graphic element can be a drawing and/or a letter and/or a number.</p> |
