Abstract

Various embodiments may relate to a component. The component includes an optically active region designed for electrically controllably transmitting, reflecting, absorbing, emitting and/or converting an electromagnetic radiation, and an optically inactive region formed alongside the optically active region, wherein the optically inactive region and/or the optically active region have/has an adaptation structure designed to adapt the value of an optical variable in the optically inactive region to a value of the optical variable in the optically active region.

First claim

1 . A component, comprising:
an optically active region, wherein an optical property of the optically active region is electrically controllable; and an optically inactive region, which is formed alongside the optically active region; an encapsulation and a carrier; wherein the optically inactive region and/or the optically active region have/has an adaptation structure designed to adapt a value of an optical variable in the optically inactive region to a value of the optical variable in the optically active region; and wherein the adaptation structure is formed between the carrier and the encapsulation.
