The voltage holding ratio and DC offset voltage in the polymer stabilized homeotropically aligned liquid crystal displays
We have studied the influences of monomers on polymer stabilized homeotropically aligned (PSHA) liquid crystal displays (LCD). PSHA-LCD is formed by mixing a small amount of monomers into nematic liquid crystal with negative dielectric anisotropy, then photo-polymerizing the mixtures. The voltage holding ratio (VHR) and the DC offset voltage of PSHA-LCD have been measured for studying the effect of photo-polymerized monomers on PSHA-LCD. We demonstrate the measurement method as well as the results.
