Transparent object with a locally limited transparent area, structured, electrically heated, manufacturing process and application

摘要

Transparent object, comprising - at least one electrically insulating transparent substrate (1), - a structured transparent coating (2), which - contains at least one electrically conductive material (2.1) or is composed thereof, - covers the surface with large transparent insulating substrate (1), - has a structure, which is formed by electrically insulating areas (2.2) free of electrically conductive material (2.1) and - comprises at least one transparent, locally limited, structured, structured, electrically heated zone (2.3) and - at least one transparent, electrically conductive zone (2.4), as well as - electrical contacts (3) to apply an electrical voltage to the coating (2), in which - the coating (2) is structured and the electrical contacts (3) they are connected so that when a voltage is applied, a current flows at least through the zone (2.3), characterized in that the zone (2.3) has the structure of a track meander-shaped conductor (2.3.1).
