Closed-Loop Power Transfer Line for Display Voltage Drop

The power transfer line is divided into multiple segments arranged in a closed-loop configuration, where each segment connects to adjacent segments to form a continuous loop. This segmentation allows the power to be distributed more evenly throughout the display panel, reducing voltage drop in any single segment while maintaining manageable complexity through modular design.

The power transfer line transitions from a linear one-dimensional arrangement to a two-dimensional closed-loop structure that surrounds the pixel array. This dimensional change enables power to reach pixels from multiple directions, reducing the effective current path length and minimizing voltage drop across the display panel.

The closed-loop power transfer line configuration creates multiple current paths that converge to provide relatively uniform voltage distribution across the pixel array. By forming a loop around the display area, the design ensures that pixels at different positions (including edges and corners) receive power with minimal voltage drop, achieving equipotential conditions across the enlarged display area.

The power transfer line structure provides different current path characteristics to different regions of the display panel. Pixels near the loop receive power through shorter paths, while pixels at opposite sides receive power through complementary paths, ensuring that each local region receives optimized power delivery appropriate to its position in the enlarged display area.

The closed-loop configuration converts the potential harm of voltage drop into a benefit by creating redundant current paths. When current flows through the loop, voltage drop in one segment is compensated by the parallel path through the remainder of the loop, transforming what would be a harmful voltage gradient into a beneficial uniform voltage distribution that eliminates bright and dark lines.

The closed-loop structure provides inherent feedback mechanisms where voltage drop in any segment is automatically compensated by the remaining loop segments. The continuous loop ensures that power distribution self-regulates, with higher current density in segments experiencing greater voltage drop, thereby maintaining uniform luminance across pattern boundaries without requiring additional control circuitry.
