Abstract

The results of the color evaluation for some monocolor, bicolor and black-white liquid crystal displays utilizing guest-host effect are presented. The polarized absorption spectra for the dichroic dyes dissolved in the liquid crystalline mixture E18 (BDH Ltd.) have been recorded and the order parameter has been calculated. Moreover, the tristimulus values of the displays color in OFF and ON states have been calculated and the changes of the color parameters under the electric field applied have been determined by using 1976 CIELAB Color System. The results have been compared with those obtained for twisted nematic liquid crystal display.
