Droplet‐size effects and lighting techniques in direct‐view PDLC displays

Abstract

Abstract— By varying liquid‐crystal droplet sizes in designated regions, direct‐view polymer‐dispersed liquid‐crystal (PDLC) displays with simpler addressing schemes are constructed. A multiple‐droplet‐size PDLC is used to hide addressing‐line voltage effects in a segmented display which requires a clear (non‐scattering) region surrounding the segments. Edge lighting improves the contrast ratio of these direct‐view displays.
