Display Panel Power Line Resistance Balancing for Uniform Emission

The power supply wiring is segmented into multiple independent power lines (first power line, second power line, third power line, etc.) that are distributed across different regions of the display panel. Each power line serves a specific area with light-emitting units, preventing the accumulation of excessive resistance that would occur in a single long wiring configuration. This segmentation ensures that voltage drop remains controlled within each local region.

Different power lines are configured with different resistance characteristics according to their local requirements. The patent specifically designs that when the resistance of the first part of the first power line is greater than the resistance of the second part of the first power line, the resistance of the first part of the second power line is less than the resistance of the second part of the second power line. This local optimization compensates for voltage drop variations and achieves uniform display across the entire panel.

The power supply system is divided into multiple parallel power lines instead of using a single power line. Each power line is responsible for a specific region, which maintains relatively simple local wiring while achieving comprehensive coverage. The segmented structure avoids the complexity of a single long wiring path while ensuring uniform power distribution.

The patent designs the power lines to achieve equipotential distribution across different regions by balancing the resistance characteristics. Specifically, the resistance compensation mechanism ensures that voltage drops across different power lines are balanced, creating equipotential zones that eliminate display non-uniformity while maintaining a relatively simple wiring architecture.
