Fabrication of Smectic Phase Guest-Host System Polarizer for Flexible Display Applications |
| 초록 |
The polarizer is one of the most essential optical element in LCDs. There is a need for coatable polarizers which are much thinner and more stable than conventional H-sheet polarizers. In our research, we aimed to fabricate “guest-host” system coatable polarizer based on highly ordered liquid crystalline monomer and dichroic dye. Firstly, we designed and synthesized a new reactive liquid crystalline monomer containing polymerizable acrylate groups as the “host” material. Then, the photocurable “guest-host” system was prepared by mixing the liquid crystalline monomer and dichroic dye. Coatable polarizers were fabricated by spin-coating above mixture on a substrate with alignment layer. The in-situ photopolymerization was carried out at room temperature by irradiating UV light to stabilized the aligned dichroic dye molecules. Finally, the dichroic ratio, order parameter and polarization efficiency of the coatable polarizer were determined by polarized UV/Vis spectroscopy. |
