DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240224712 titled 'DISPLAY DEVICE
Simplified Explanation: The patent application describes a display device with a unique cathode electrode layer that includes a conductive organic material layer to absorb heat from a laser and reduce damage to the third electrode layer.
- The display device includes a substrate, an organic light-emissive layer, and a cathode electrode layer.
- The cathode electrode layer consists of a first electrode layer, a second electrode layer made of a conductive organic material, and a third electrode layer.
- The second electrode layer absorbs heat from a laser, protecting the third electrode layer and reducing the penetration of external defect-causing factors into the organic light-emissive layer.
Key Features and Innovation:
- Unique cathode electrode layer design with a conductive organic material layer.
- Heat absorption capability of the second electrode layer to protect the third electrode layer.
- Reduction of external defect-causing factors penetrating the organic light-emissive layer.
Potential Applications:
- OLED displays
- Lighting applications
- Electronic devices
Problems Solved:
- Damage to the third electrode layer from laser heat
- Penetration of external defect-causing factors into the organic light-emissive layer
Benefits:
- Enhanced durability of the display device
- Improved performance in high-heat environments
- Reduced risk of defects in the organic light-emissive layer
Commercial Applications: Potential commercial applications include OLED TVs, smartphones, tablets, and other electronic devices requiring high-performance display technology.
