62.1: Reduction of the Threshold Voltage and Enhancement of Contrast Ratio in Liquid Crystal Devices with BaTiO3 Nanoparticle Embedded Surface Alignment Layers

Herein, we report the effect of a 40% weakening of the surface polar anchoring energy of liquid crystal devices when the polyimide layers were doped with the nanoparticles of BaTiO3. This effect leads to the reduction of the threshold voltage by 6% and also the enhancement of the contrast ratio of t...

Zusammenfassung:Herein, we report the effect of a 40% weakening of the surface polar anchoring energy of liquid crystal devices when the polyimide layers were doped with the nanoparticles of BaTiO3. This effect leads to the reduction of the threshold voltage by 6% and also the enhancement of the contrast ratio of twisted‐nematic liquid crystal displays (TN‐LCDs) at the saturation voltage by 130%.
