METHOD FOR ELECTRICALLY CONTROLLING A FUNCTIONAL ELEMENT EMBEDDED IN A GLAZING UNIT

A method for controlling a glazing unit having electrically controllable optical properties, wherein the glazing unit includes a composite pane having an outer pane and an inner pane which are connected to one another via a thermoplastic intermediate layer, a functional element is arranged between the outer pane and the inner pane and has an active layer having electrically controllable optical properties between a first planar electrode and a second planar electrode, the optical properties are controlled by a control unit, wherein the control unit is connected to at least two transparent planar electrodes of the functional element, an electrical voltage is applied between the planar electrodes by the control unit, and an inverse function is used to determine a magnitude of the electrical voltage.
