AI Technical Summary
Technical Problem
Existing electrically controllable functional elements face challenges in achieving precise, stepwise switching of optical properties due to complex electrical contact mechanisms, especially as the controllable areas become smaller.
Method used
A functional element design with busbars arranged on side edges, divided into sections by separators, allowing independent control of individual regions through separate voltage application, enabling targeted and precise switching of optical properties.
Benefits of technology
Facilitates precise, targeted control of optical properties across the functional element, improving switching precision and uniformity while simplifying electrical contact, reducing complexity and enhancing aesthetic appeal.

Abstract
In a functional element (5) having electrically controllable optical properties having a plurality of side edges (4.1, 4.2, 4.3, 4.4), comprising a first carrier film (14) having at least a first planar electrode (12), a second carrier film (15) having a second planar electrode (13), and an active layer (11) arranged flatly between the first planar electrode (12) and the second planar electrode (13). - The first busbar (18) and the second busbar (19) are arranged on at least one first side edge (4.1), and - The first carrier film (14) has at least one first concave portion (10.1), and the second carrier film (15) has at least one second concave portion (10.2). Here - The first busbar (18) is arranged on the surface of the second carrier film (15) facing away from the second planar electrode (13), passes through at least one second concave area (10.2), and is electrically conductively in contact with the first planar electrode (12). - The second busbar (19) is arranged on the surface of the first carrier film (14) facing away from the first planar electrode (12), passes through at least one first concave area (10.1), and is electrically conductively in contact with the second planar electrode (13). - At least one first busbar (18) is divided into at least one first section (18.1) and at least one second section (18.2), which can be controlled independently of each other and / or at least one second busbar (19) is divided into at least one first section (19.1) and at least one second section (19.2), which can be controlled independently of each other, and - The first concave portion (10.1) and the second concave portion (10.2) are functional elements (5) arranged alternately with respect to each other.
