COMPOSITE PANE HAVING ELECTRICALLY CONTROLLABLE OPTICAL PROPERTIES, AND COMPOSITE PANE ARRANGEMENT

摘要

The invention relates to a composite pane arrangement, in particular vehicle glazing unit, comprising a composite pane (1) which has a functional element (4) with electrically controllable optical properties, an actuation unit (13) for controlling the optical properties of the functional element (4), a temperature sensor (16), a heating current source (15) for applying a heating current to the busbars (11a, 11b) of the heating resistance layer (11), and a heating control unit (14) for controlling the supply of heating current to the heating resistance layer. The heating control unit (14) is suitable for supplying heating current, as soon as a temperature which is measured by the temperature sensor (16) falls below a prespecified limit value, in order to increase the temperature above the limit value.
