P-58: Diffuse H-PDLC Reflective Displays: An Enhanced Viewing-Angle Approach

We demonstrate a Holographic-Polymer Dispersed Liquid Crystal (H-PDLC) with an enhanced viewing-angle, formed by writing a diffuse hologram structure directly into our H-PDLC material. We model the diffuse H-PDLC reflectance by summing over the contributions of discrete grating domains of differing orientations. We use a normal distribution function to weight each orientation to describe the grating densities. SEM studies were performed to determine the morphologies and orientations of multiple gratings within the sample.
