NOVELTY - The coating, which is applied on a carrier (15), comprises a functional layer (11), which is protected by a protective layer (12) and has a cell structure, which is constructed from individual cells. Between the individual cells, cell interstices are provided, in which a barrier medium (14) is provided. The cells are formed in quadratic-, rectangular-, triangular-, parallelogram-, rhombus-, honeycomb- or are circular manner or consist of mathematic confessed form for a penrose-parquetting. The functional layer is oxide layer, which consists of transparent, conductive oxide.    USE - Coating useful in flat object, a facade element or glass disc or solar collector (all claimed) for architecture or the automotive industry.    ADVANTAGE - The coating can be economically produced with good durability.    DETAILED DESCRIPTION - The coating, which is applied on a carrier (15), comprises a functional layer (11), which is protected by a protective layer (12) and has a cell structure, which is constructed from individual cells. Between the individual cells, cell interstices are provided, in which a barrier medium (14) is provided. The cells are formed in quadratic-, rectangular-, triangular-, parallelogram-, rhombus-, honeycomb- or are circular manner or consist of mathematic confessed form for a penrose-parquetting. The functional layer is oxide layer, which consists of transparent, conductive oxide such as indium oxide or tin oxide or zinc oxide. The protective layer consists of silicon oxynitride. The barrier medium has the chemical composition of protective layer. The functional layer is produced through physical or chemical vapor deposition. The cell structure of the functional layer is produced through using a mask during coating process, through wearing out after the coating by laser or mechanically produced through a lithographic process. The carrier is a glass or a glazed material or a plastic or ceramic or a metal.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of a coating applied on a carrier.
