Grayscale-Memory Spatial Light Modulator with Polymer-Dispersed Phase-Transition Liquid Crystal

Abstract

A new storage-type spatial light modulator has been developed which uses a polymer-dispersed phase-transition liquid crystal film and a photoconductor for high-brightness projection displays. The liquid crystal film containing micrometer-sized chiral nematic liquid crystal domains subdivided by a unique honeycomb polymer network functions as a memory layer for an input image. The liquid crystal domains independently maintain the binary alignment states in the opaque (1ight-scattering) cholesteric phase or transparent nematic phase. Grayscale images can be displayed according to the spatial distribution of the bistable liquid crystal domains. The device exhibits rapid response of a few ms and a limiting resolution of 32 Ip/mm. It has the advantages of high transmittance without polarizers and ease of fabrication due to the free-standing liquid crystal film.

“…[12] For clarity, the ocatadecylamine contributions to the -CH 2 -and -CH 3 bands around 2900 cm ±1 [11a] were omitted in Figure 3. [13] Due to the hydrophobic and oleophobic character of the monolayer surface, the sample emerged completely dry and free of traces of bulk liquid contamination from both the acid and ocatadecylamine solutions.
