Abstract
The disclosed embodiments relate to lateral migration of particles in a totally internally reflective displays. In certain embodiments, the reflective image displays include partial and full walls to form partitions within the display. The walls mitigate diffusion and lateral migration or drift of electrophoretically mobile particles due to lateral electric fields at adjacent pixels. This improves image quality, bistability and long-term display performance.
