Stretchable Display Electrode Structure for Stable LED Interconnects

The patent employs flexible thin film structures for electrodes, conductive layers, and encapsulation. The use of thin film transparent electrodes, flexible conductive layers, and thin film encapsulation layers enables the display apparatus to be stretched while maintaining electrical connectivity and structural integrity, directly resolving the contradiction between rigidity and flexibility.

The patent utilizes composite material structures combining organic and inorganic layers. The encapsulation structure comprises alternating organic encapsulation layers and inorganic encapsulation layers, creating a composite that provides both flexibility from organic materials and structural stability from inorganic materials, simultaneously achieving stretchability and structural integrity.

The flexible thin film electrode structures maintain electrical connectivity through their continuous conductive paths that can deform elastically during stretching. The thin film nature allows the electrodes to flex and stretch without breaking, ensuring long-term durability while maintaining reliable electrical connection throughout the stretching cycles.

The encapsulation structure with organic and inorganic layers provides protective cushioning to the electrode structures before damage can occur. This multi-layer encapsulation protects the electrodes from mechanical stress, moisture, and environmental factors during stretching, enhancing durability while maintaining electrical connectivity.

The patent employs a composite encapsulation structure with alternating organic and inorganic layers. This composite approach provides enhanced durability through the synergistic properties of different materials - organic layers provide flexibility and stress distribution while inorganic layers provide barrier properties - without requiring excessive individual layers, thus managing complexity through material selection rather than layer multiplication.

The encapsulation layers serve multiple functions simultaneously: mechanical protection during stretching, moisture barrier, and structural support. By designing layers that fulfill multiple roles, the patent reduces the need for additional specialized layers, thereby limiting the increase in device complexity while achieving enhanced durability.
