In this paper we present results concerning reflective LCD's with different alignment layer types. We made thought-out interpretations of the asymmetrical reflectance and current responses. The asymmetry is the result of an internal voltage. In our m

The application of broadband cholesteric reflectors in birefringent colour reflective LCDs is described. As compared to metallic reflectors, contrast and colour saturation are better, while the brightness is comparable. Moreover, when a cholesteric r

In this paper, the polymerization of sulfur-containing precursor molecules to poly(isothianaphthene) (PITN) is described. Most attention has been devoted to the polymerization of dithiophthalide, as other useful precursors were synthetically less acc

The orientation of iiquid crystals on spherulitic polymeric alignment layers can give both a radial and a concentric director pattern. These types of orientation lead to LCDs having a wide and symmetric viewing angle. Moreover, greyscale inversion is

The results of some mechanistic studies on the formation of poly(isothianaphthene) from phthalic anhydride and phthalide by reaction with phosphorus pentasulfide (P4S10) are described. Based on the observed intermediates during the polymerization and

A new route for the formation of the low bandgap polymer poly(isothianaphthene) is presented. The route comprises the reaction of phthalic anhydride or phthalide with phosphorus pentasulfide at elevated temperatures ( T ⩾ 120 °C), and leads to the
