Abstract
Polymer disperse liquid crystal (PDLC), which works by changing the refractive index matching and mismatching between the injected liquid and glass. The light cannot pass through the PDLC film by the index mismatching when the applied voltage turn off, called off state of the PDLC. Otherwise, if there is the electric field applied, the liquid crystals (LC) inside the PDLC droplet will be rotated to parallel arrangement. Than light will directly pass through the film by index match, called on state type. Due to these important properties LC/polymer mixture recently are studies for a wide variety of application, especially most popular in the display and smart window devices. In this work, we developed a novel polymer disperse liquid crystal (PDLC) display using heat curing method. In this article doped with small amount of (about 5 wt%) 3ïm-diameter silver nanospheres into PDLC. The silver nanospheres can construct the partial electric field between each other in the electric field applied. Therefore these partial electric field can decrease the operating voltage to 40V and also have high contrast and on state transmittance about 73%.
