Light Emitting Panel Electrode Layout for Lower IR Drop

The patent divides the conductive portions into multiple insulated segments (first conductive portions and second conductive portions) that can be independently controlled. This segmentation allows different current paths and current magnitudes for different regions, enabling high luminous efficiency in active regions while reducing overall power consumption and IR drop by limiting current in less active regions.

The patent implements local quality by providing different electrical connection configurations for different light emitting devices. Some devices have their first electrodes connected to first conductive portions while others connect to second conductive portions, allowing localized optimization of current distribution. This enables high current (high luminous efficiency) where needed and low current (low power consumption) where not needed, resolving the contradiction between luminous efficiency and power consumption.

The conductive portions are segmented into multiple insulated first and second conductive portions with different electrical connection configurations. This segmentation creates multiple independent current paths, allowing the system to distribute current flow and avoid concentration of high current in single paths, thereby reducing IR drop while maintaining luminous efficiency in active regions.

By providing different electrical connection configurations for different devices (some connecting first electrodes to first conductive portions, others to second conductive portions), the patent enables local optimization where high current is applied only to regions requiring high luminous efficiency, while other regions use lower current, thus minimizing overall IR drop.
