REELABLE OLED CURTAIN

摘要

This invention relates to an organic light-emitting or light-absorbing device (20), comprising a light unit (30), a first flexible protection layer (35), and a second flexible protection layer (25). The light unit comprises a flexible bottom layer (24) having at least one first barrier layer (27). A bottom electrode (22) is provided on the flexible bottom layer, and an organic layer stack (21) is deposited on top of the bottom electrode. Furthermore, the organic layer stack is designed to emit or absorb light. The light unit has a top electrode (23) arranged on top of the organic layer stack and at least one second barrier (28) layer provided on top of the top electrode. The first flexible protection layer and the second flexible protection layer are arranged to encase the light unit, such that a large-area support structure is provided for the device. The large-area support structure provides a reelable organic light-emitting or light- absorbing device. The invention applies to flexibility and a method of adjusting this flexibility to the specific demands of specific large-area applications, such as space partition devices and roller blinds.
