Abstract
A polymer dispersed liquid crystal (T-PDLC) confined in a 90° twisted cell was discussed. A comparison between the contrast ratios of T-PDLC and conventional PDLC was done by measuring their voltage-dependent transmittance. The T-PDLC was found to be polarization independent and was exhibiting higher contrast ratio and more efficient light scattering than conventional PDLC. The study on a black and white segmented-alphabet reflective display using 2% dye-doped T-PDLC showed a higher contrast ratio.
