1Area of stationary object
If multiple radiation-emitting organic components are connected to form large-area devices, then the emission area is increased, but the device complexity increases
Solution Approach 1:
The radiation-emitting device is divided into multiple independent organic components (first radiation-emitting organic component, second radiation-emitting organic component, etc.), each with its own substrate, electrodes, and encapsulation. These segmented components are connected through contact bridges, allowing the system to achieve large emission areas while maintaining manageable complexity through modular design.
2Adaptability or versatility
If flexible contact bridges are used to connect components, then the adaptability and flexibility are improved, but the manufacturing precision requirements increase
Solution Approach 1:
Contact bridges with flexible design are used to connect the radiation-emitting organic components. These flexible contact bridges can adapt to slight misalignments and deformations, providing mechanical flexibility and electrical connectivity while accommodating variations in component positioning during assembly.
3Adaptability or versatility
If deformable sheathings are applied to enable curved and foldable configurations, then the adaptability is improved, but the structural stability may deteriorate
Solution Approach 1:
The device incorporates deformable sheathings that allow the rigid organic components to be arranged in curved or foldable configurations. The sheathings provide mechanical protection and environmental sealing while accommodating dynamic shape changes, enabling the device to transition between different configurations (flat, curved, folded) while maintaining structural integrity during operation.
