Display Device Power Sensing Line Static Discharge Extension

The patent introduces a power sensing extension line that extends from the power sensing line to the edge of the substrate, serving as an intermediary path for static electricity to discharge. This extension line acts as a mediator that provides a safe discharge path away from the critical power sensing line, preventing charge concentration and disconnection defects while allowing lighting inspection to proceed

The patent converts the harmful static electricity that causes disconnection defects into a beneficial discharge path through the power sensing extension line. By providing a dedicated extension line, the harmful static charge is redirected to safely discharge at the edge of the substrate, transforming the potential harm into a controlled discharge mechanism that protects the power sensing line

The power sensing extension line serves as an intermediary structure that prevents direct disconnection in the power sensing line. By providing this extension path, the patent eliminates the formation of oxygen or moisture paths that would otherwise occur at disconnection points, thereby protecting the encapsulation integrity and extending device lifespan while maintaining lighting inspection capability

The patent implements prior cushioning by pre-providing the power sensing extension line as a protective structure before any disconnection can occur. This extension line acts as a preventive measure that cushiones against the formation of oxygen or moisture paths, ensuring the encapsulation remains intact and the device maintains its lifespan even during lighting inspection processes
