Abstract

A vehicle window has a plurality of integrated electro-optical elements, wherein the electro-optical elements have a common supply voltage, wherein the integrated electro-optical elements are controllable individually or in groups such that the electro-optical elements change the optical properties of the window at the respective location, wherein a first logical interface for feeding in the common supply voltage and a second logical interface for feeding in a common control signal are provided for controlling the electro-optical elements and for providing the common supply voltage, wherein, downstream from the logical interface, the control signal is converted into control signals for the control of the integrated electro-optical elements individually or in groups, wherein the physical interface is arranged on one of the outer faces of the window, wherein the physical interface for the first logical interface and the second logical interface has, together, 3 or 4 electrical connections.
