Paper white pdlc system |
| abstract |
The invention relates to a paper white PDLC system which between 2 electrode layers contains a PDLC film comprising a liquid crystal mixture forming microdroplets in an optically isotropic, transparent polymer matrix; in which one of the refractive indices of the liquid crystal mixture is matched to the refractive index of the polymer matrix nM; the transmission of which can be varied by applying an electrical voltage, characterized in that the PDLC film exhibits the following properties: |n^¨B7-nM| » 0.05 wherein n^¨B7 is the mean refractive index of the liquid crystal mixture defined via n^¨B72 = 1/3(m¿e?2+2no2); mean droplet diameter « 2 νm; thickness of PDLC film 5 νm « d « 75 νm; degree of backscatter » 20 %. |
