| Abstract: | Abstract— STN‐LCDs embedded with special metal nanoparticles of Ag/Pd are shown to be useful for a direct‐multiplexed dot‐matrix STN‐LCD with 320 × 240 pixels and show a fast response time by 3–5 times compared to those without nanoparticles. This phenomenon is shown to be attributed to the reduction of rotational viscosity by 70% at room temperature and by 30% at a low temperature (?20°C). The alteration of elastic constants by doping nanoparticles could be also essential. |
