Composite disc with electrically controllable functional element and electrically controllable reflective element

Abstract

Composite pane (100) for a projection arrangement, comprising: - an outer pane (1) and an inner pane (2), which are connected to each other via a thermoplastic intermediate layer (3); - an electrically controllable functional element (4), which can be switched to at least an opaque state and a transparent state; and - an electrically controllable reflective element (5), which can be switched to at least a transparent state and a reflective state, wherein the electrically controllable functional element (4) extends over a functional area (F) of the composite pane (100) and the electrically controllable reflective element (5) extends over a projection area (P) of the composite pane (100), wherein the projection area (P) at least partially coincides with the functional area (F) and the electrically controllable reflective element (5) is visible in transmission through the composite pane (100).The laminated pane (100) is arranged in front of the electrically controllable functional element (4) when viewed from the inner pane (2) to the outer pane (1), wherein the laminated pane (100) (a) comprises an infrared-reflecting coating (7) which extends at least over the functional area (F) and is arranged behind the electrically controllable functional element (4) when viewed through the laminated pane (100) from the inner pane (2) to the outer pane (1), or (b) comprises a heating layer (10) which extends at least over the functional area (F).
