Double-layered light shutter using long-pitch cholesteric liquid crystal cells

Dye-doped cholesteric liquid crystal light shutter with a polymer-dispersed liquid crystal film

“…To compare the transmission characteristics of the fabricated dye-doped light shutter containing a PDLC film with a double-cell light shutter [12], we fabricated a double-cell ChLC light shutter. was much lower than 3 wt% for a double-cell light shutter, the specular transmittance of the proposed light shutter, which contains a PDLC film, was lower than that of the double-cell light shutter, which contains a ChLC cell, because the transmittance [haze] of a PDLC cell can be lower [higher] than that of a ChLC cell in the opaque state [17].…”

“…Recently, our group proposed a light shutter device using two ChLC cells [12]: a light-scattering cell and a light-absorption cell. Although this double-cell light shutter has low transmittance in the opaque state because the dye molecules are aligned parallel to the substrate, it suffers from disadvantages that include low transmittance in the transparent state, high thickness, and high fabrication cost because of the double-cell structure.…”
