- The addition of dichroic dye to liquid crystal (LC) display makes an optical shutter easily without polarizer. However, the dichroic dye induces one significant problem an inadequate contrast. The general reason for this is the less available UV light for polymerization due to absorption of UV light by trapped dye molecules in polymer matrix. This problem results into accumulation of residual pre-polymer molecules and induces slow polymerization that produces larger droplet size for LCs. This in turns produces insignificant electro-optical properties for dye-PDLC display. Our strategy proposed a new way to overcome this difficulty by adjusting the some factors, e.g., pre-polymer, initiator contents and curing time. © 2012 American Scientific Publishers.
