Description

Composite window panel assembly and motor vehicle having such a composite window panel assembly Technical Field The present invention relates to a composite louver assembly having a first louver, a second louver, and an active layer disposed between the first louver and the second louver. The active layer is switchable between different light transmission states. Furthermore, the invention relates to a motor vehicle having such a composite pane arrangement. Background Composite window panel assemblies and motor vehicles having composite window panel assemblies are known in the art in various embodiments. Known composite louver assemblies typically include a first louver, a second louver, and an intermediate layer disposed between the first louver and the second louver. The known intermediate layer has a carrier film and an active layer arranged between the carrier films. A conductive coating is applied over the entire surface of the carrier film on the side thereof facing the active layer. According to the control state of the conductive coating, the transmission characteristic of the active layer for light can be controlled. In particular, the active layer is thereby switchable between a blocking state in which it acts like a diffuser or absorber, and a transmissive state in which light can pass through the composite louver assembly substantially without scattering or absorption. However, the composite window plate assembly known from the prior art can only change the transmission characteristics of the active layer over the whole area. Disclosure of Invention The object of the present invention is to provide a composite pane arrangement whose transmission properties can be adapted specifically to specific requirements. Furthermore, the object of the invention is to provide a motor vehicle with such a composite pane arrangement. This object is achieved according to the invention by a composite window panel assembly having the features of patent claim 1 and by a motor vehicle having the features of patent claim 13. Thus, according to the present invention, there is provided a composite glazing panel assembly comprising a first glazing panel, a second glazing panel, an active layer (AKTIVE SCHICHT) disposed between the first and second glazing panels, and two electrically conductive layers. The active layer is disposed between the first conductive layer and the second conductive layer. The conductive layer is thus arranged between the first louver and the active layer or between the second louver and the active layer. The first and second conductive layers each include a section that is electrically insulated from each other. The sections of the first electrically conductive layer can be actuated individually (einzeln), i.e., independently of one another, by means of a first control unit. The sections of the second conductive layer can be actuated individually by means of a second control unit. The core idea of the invention is therefore that by providing two control units, both conductive layers can be controlled independently of each other, and furthermore, the control units are each connected to a section of the relevant conductive layer, so that individual sections of the conductive layers can also be controlled independently of each other. Thus, the active layer can be switched between different light transmission states in a simple manner. The sections of the first conductive layer may have a different shape or arrangement, in particular, independently of the shape and/or arrangement of the sections of the second conductive layer. Thus, it is not necessary that a section of the first conductive layer be perfectly aligned with an associated section of the second conductive layer in the composite glazing panel height direction. In a preferred embodiment of the composite louver assembly according to the invention, the segments being manipulated have a defined electrical potential. The defined potential of the section of the first conductive layer is different from the defined potential of the section of the second conductive layer. For example, sections of the same conductive layer have the same potential. The composite glazing panel assembly comprises, for example, exactly one active layer and exactly two conductive layers. Thus, the composite glazing panel assembly is, for example, free of other active layers and other conductive layers. The active layer can be switched between different light-transmitting states, in particular a transparent state or a transmissive state, an overall (in particular completely) opaque state, i.e. a blocking state, and/or a partially opaque state, in which only a partial region of the active layer is in an at least partially, in particular completely, opaque state. In an exemplary embodiment of the composite pane arrangement according to the invention, the first control unit is configured such that, when the first control unit actuates at least one defined section of the f
