59.4L: Late‐News Paper: The Biprimary Color System for E‐Paper: Doubling Color Performance Compared to RGBW

We demonstrate the “biprimary” color system with dual particle electrophoretic dispersions and a 3-electrode system. Preliminary contrast ratios reach 10:1. Furthermore an electrokinetic cell is demonstrated confirming basic functionality for EKD panels. A theoretical pixel simulation confirms biprimary doubles the color performance compared to RGBW pixels.
