Glazing assembly, comprising in succession:

Functionalized security glazing

A transparent glazing, and a control method thereof, with a field of view that can be darkened over a portion of its surface by electrically controlling at least one functional element incorporated into a multilayer composite, the light transmission of which glazing can be varied reversibly. The functional element, for example a solid-state electrochromic multilayer system, includes at least one electrochromic functional layer enclosed between two surface electrodes. The surface electrodes and their leads are matched to one another and spaced spatially with respect to one another such that darkening starts at one edge of the functional element and, with a remaining voltage applied between the surface electrodes, propagates continuously over the surface of the functional element until it is completely and uniformly colored. The glazing can be used as an electrically controllable sunshield for windshields of vehicles or the like.
