Analysis of electro-optic properties of a polymer network liquid crystal display with crossed polarizers

An active-matrix polymer network liquid crystal display (AMPNLCD) of 1.79 '' QCIF(176 x 144) was fabricated. The operating mode of normally black was reversed to normally white by using crossed polarizers. The contrast ratio, as a result, was drastically increased, which was comparable to a conventional liquid crystal display. The response time at a typical driving voltage, 2.8 V, was also fast enough to play still image smooth. The electro-optic properties of AMPNLCD with crossed polarizers were evaluated and discussed.
