AI Technical Summary

Technical Problem

Organic light-emitting diode (OLED) display panels face challenges in achieving high Pixels Per Inch (PPI) due to signal line resistivity issues, leading to signal delay and degraded display quality, especially in larger VR or AR applications.

Method used

Incorporating a resistance reducing electrode at a different layer and in parallel with signal lines, such as transverse direct-current high-level signal lines, to reduce signal line resistance and improve display quality.

Benefits of technology

The resistance reducing electrode effectively lowers signal load, enhancing display quality and uniformity by reducing resistances in signal lines, particularly in larger OLED display panels.
