Abstract
The invention concerns a laminated glass pane (1) with at least a rigid pane and a flat electrically controlled functional element (2) as well as at least a thin electrically conductive coat (5), wherein, in accordance with the invention, the coat (5) also constitutes a flat electrode of the functional element, the coat being capable of being heated by being powered with an electric voltage, independently of the power supply of the functional element (2). Thus, unwanted variations of the optical properties of the functional elements are reduced when such a laminated glass pane is used at highly fluctuating temperatures, in particular at low temperatures.
Claims14
A laminated panel assembly comprising:
- at least one rigid panel;
- an electrically controllable flat functional element;
- and
- at least one electrically conducting thin film that forms a flat electrode of the functional element, the thin film being connected to receive an electrical voltage that heats the thin film independently of a power supply for the functional element.
A method for using a functional element having electrically controllable properties, combined with a laminated panel assembly, in which the laminated panel assembly comprises at least one rigid panel and at least one electrically conducting film, wherein the electrically conducting film is connected to receive an electrical voltage that heats the thin film independently of a power supply for the functional element, when an actual temperature of the functional element, determined by a temperature sensor, is below a predetermined setpoint temperature.
