(a) Illustration of the μ-rubbing apparatus and the direction of LC molecules orientation. (b) The vertically aligned twist mode is schematically illustrated in the OFF and ON state.
(Color online) Polarizing microscope photographs and the corresponding iso-intensity curves of the twisted vertically aligned four-domain cell under different voltages created by -rubbing. The optical simulations of the viewing angle characteristics at the same voltages are also shown.
Experimental and calculated transmission-voltage curve for the twisted vertically aligned four-domain cell. The dynamic response time is also shown in the inset.
(Color online) Results of 2DIMMOS calculations for the director orientation of the twisted vertically aligned cell at 0, 3.5, and 5 V. Calculated transmittance vs position on the same section is also plotted above.
