Abstract
An improved functional element having electrically controllable optical properties includes a stack sequence formed of a first carrier film, a first surface electrode, an active layer, a second surface electrode, and a second carrier film, wherein the second carrier film is folded around the edge of the first carrier film at least at one side edge and seals an exit surface of the active layer at the side edge.
Claims20
A functional element having electrically controllable optical properties, comprising:
- a stack sequence formed of a first carrier film, a first surface electrode, an active layer, a second surface electrode, and a second carrier film, wherein
- the second carrier film is folded around the first carrier film at least at one side edge and seals an exit surface of the active layer at the side edge,
- at least one section of an overhanging region is materially bonded to an edge region of the first carrier film, is permanently pressed together, is fused, and/or is glued, and
- the carrier film is implemented such that the carrier film prevents diffusion of plasticizers through the carrier film.
A method for producing a functional element having electrically controllable optical properties, comprising:
- a) providing a stack sequence formed of a first carrier film, a first surface electrode, an active layer, a second surface electrode, and a second carrier film is provided,
- b) cutting back the first carrier film at at least one side edge by a region of the width u, by which means an overhanging region of the second carrier film is formed, and
- c) folding the overhanging region of the second carrier film around the cut-back side edge of the first carrier film.
