چکیده

We have proposed composite films composed of a molecular-aligned polymer and liquid crystal (LC) for substrate-free liquid crystal displays with high-contrast images. We successfully controlled the molecular alignment of the LC and formed molecular-aligned LC droplets in the polymer by controlling the fluidity of the LC/monomer mixture and the curing rate of the monomer. key words: substrate-free display, liquid crystal, polymer, composite film

Surface Wetting Characteristics of Rubbed Polyimide Thin Films

Amide and imide based polymers are a catalogue of versatile materials that have a wide range of applications from scientific interests to commercial products because of their great thermal stability, excellent electric properties, highly mechanical strength, and superior chemical resistance (Sroog, 1976). In a thin film form, polyimides have been found to have many important uses in optoelectro...

Multidomain LCDs and Complex Optical Retarders Generated by Photo-Alignment

Photo-alignment of liquid crystal displays (LCDs) with our linear photo-polymerisation (LPP)technology enables well defined boundary conditions such as high anchoring strength and stable, pretilt angles [1,2]. We report a photo-aligned four-domain vertical aligned nematic (VAN)-LCD. The display is compensated by a new VAN-compensator which is based on our LPPand liquid crystal polymer (LCP)tech...

Polymer-Layer-Free Alignment for Fast Switching Nematic Liquid Crystals by Multifunctional Nanostructured Substrate.

A novel polymer-layer-free system for liquid-crystal alignment is demonstrated by various shaped indium tin oxide (ITO) patterns. Liquid crystals are aligned along the ITO line pattern and secondary sputtering lithography can change the shape of the ITO line pattern. Different shapes can control the direction and size of the pretilt angle. This effect eliminates defects and reduces the response...

Phase switching of ordered arrays of liquid crystal emulsions

Polymer dispersed liquid crystals (PDLC) are a well established technology for electrooptic devices used in displays and light switches. They rely on dispersions of nematic liquid crystal material in a polymer matrix. In the absence of an electric field, the director field n(r), which characterizes the local average orientation of the rodlike nematic mesogens, is randomly oriented, leading to a...

1 The POLICRYPS structure In the last decades, great attention has been devoted to the realization of switchable holographic structures in liquid crystalline composite materials [1]. In particular, it has been shown that diffraction gratings based on Holographic Polymer Dispersed Liquid Crystals (HPDLC), that means droplets of Nematic Liquid Crystal (NLC) dispersed in a polymer matrix (see inse...
