    Abstract: A method for electrical control of a functional element incorporated in a glazing unit and having electrically controllable optical properties. 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 connected to at least two transparent planar electrodes of the functional element, and an electrical voltage is applied between the planar electrodes by the control unit. An inverse function is used to determine a magnitude of the electrical voltage, and also as a temperature-dependent linearization function and a temperature of the functional element or composite pane is detected by a temperature sensor.

    Abstract: A method for electrically controlling a functional element with electrically controllable optical properties enclosed in a glazing unit includes controlling the optical properties by a control unit connected to two transparent flat electrodes of the functional element, and applying a voltage by the control unit between the flat electrodes and the polarity of the voltage is periodically changed. The voltage has a trapezoidal profile and by the control unit an increasing electrical voltage is applied for charging the functional element, the electrical voltage increasing to a first peak value, the electrical voltage is reduced from the first peak value to a final voltage for discharging the functional element, the functional element is charged with the increasing electrical voltage with reversed polarity, wherein the electrical voltage increases to a second peak value, the electrical voltage is reduced from the second peak value to the final voltage for discharging the functional element.

    Abstract: A glazing unit having electrically controllable optical properties and multiple independent switching regions includes a composite pane with an electrically controllable functional element and a control unit to control the optical properties of the functional element. The functional element has an active layer having electrically controllable optical properties between a first flat electrode and a second flat electrode. The first flat electrode is divided by at least one insulation line into at least two separate electrode segments, wherein an electric voltage is applicable between each electrode segment of the first flat electrode and the second flat electrode independently of one another in order to control the optical properties of the section of the active layer situated therebetween. The second flat electrode is not segmented or is segmented to a lesser extent than the first flat electrode. The control unit is adapted to ascertain the temperature of the composite pane.
