Abstract (en)
[origin: WO2022028931A1] The invention relates to a laminated pane with an electrically controllable functional element which can be switched in segments, at least comprising a first ply (1) and a second ply (2) which are connected together via an intermediate layer (3,) and comprising a functional element (5) which is integrated into the intermediate layer (3), wherein - the functional element (5) comprises at least a first carrier film (14), a first plate electrode (12), an active layer (11), a second plate electrode (13) and a second carrier film (15) which are arranged flatly on top of each other and in the mentioned order, - the first plate electrode (12) is divided into multiple segments (17) by means of at least one separating line (16), - electrical contact is established between a group of first busbars (18) and the first plate electrode (12), - electrical contact is established between at least one second busbar (19) and the second plate electrode (13), and in the region of at least one separating line (16) at least one recess (20) is made into the first plate electrode (12) and surrounds at least a portion of the first plate electrode (12) and electrically insulates the portion located within the recess (20) from the surface region of the first plate electrode (12) located outside the recess (20).
