P‐252: <i>Late‐News Poster:</i> Excellent Bistable Electrophoretic Displays with Contrast Ratio up to 81.9

The performance of electrophoretic displays is greatly dependent on the stability of the suspension. In this paper, the factors affecting the stability of electrophoretic colloids were well discussed, including the density difference between particles and solvents, system viscosity, solvation, and agglomeration. These above factors affected the dispersion stability of the system and the lifetime of the display. By optimizing these factors, the features of display panel were greatly improved, and exhibited excellent performance. Our work can be the guidance to the manufacturing of electrophoretic e‐ink display industry.
