Display Panel Redundant Electrode Reflectivity Management

The patent converts the harmful reflective property of redundant electrodes into a beneficial function by filling the electrode regions with light-emitting materials. The previously harmful metal electrodes become useful light-emitting structures when abnormal LEDs are detected, transforming the defect into a repair mechanism that improves display reliability while eliminating the reflectivity problem.

The patent applies different treatments to different regions: functional structures (light-emitting materials) are selectively filled in regions where redundant electrodes are located and abnormal LEDs are detected, while other regions maintain their original structure. This localized approach ensures that reflectivity is reduced only where necessary, while preserving the overall display quality and enabling targeted repair compensation.

The patent changes the optical parameters of the redundant electrode regions by filling them with light-emitting materials having different refractive indices and optical properties. This transformation modifies how light interacts with these regions, converting them from highly reflective metal surfaces into light-emitting structures that enhance rather than degrade display brightness and quality.

The patent transforms the previously harmful exposed metal electrodes into beneficial light-emitting structures. By filling the electrode regions with functional materials, the design converts the manufacturing simplicity of exposed electrodes into an opportunity for active light emission, thereby improving display effect while maintaining ease of manufacture through the same fabrication processes.
