Effect of the polarisation direction and incident angle of a UV light on the electrooptical response of the polymer-stabilised vertically aligned in-plane switching liquid crystal

Abstract

We investigated the effect of the polarisation direction and incident angle of a UV light on the electrooptical properties of the polymer-stabilised vertically aligned in-plane switching (PS-VAIPS) liquid crystal. The PS-VAIPS sample cured with a UV light whose polarisation was parallel to the projected direction of the inplane electric field showed greater transmittance, faster rising time and slower falling time than the sample cured with a UV light with a perpendicular polarisation to the electric field. In addition, the PS-VAIPS sample showed slower rising time and faster falling time with increasing incident angle of the UV light.

Dependence of the reflection spectrum of the polymer-stabilized cholesteric liquid crystal on the length of the diacrylate and monoacrylate reactive mesogen molecules

“…[11][12][13] The electrooptical properties of the PSCLC is strongly affected by the morphology of the polymer networks. [14][15][16][17][18][19][20][21][22][23][24][25][26][27] There have been previous reports about the correlation between the electro-optical properties of the PSCLC and the polymer network morphology. [14][15][16] Most of the reports were about the effect of the UV intensity 15) and the UV curing temperature 16) on the electro-optical properties of the PSCLC.…”
