Image of FIG. 1.
FIG. 1.

The scanning electron microscope image of polymer columns (a) top wide view and (b) magnified oblique view. The region A has thin polymer layer with vertical micro-fibrils.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Microscopic texture of a homeotropically aligned LC cell. (b) The conoscopic image confirming homeotropic alignment. (c) Microscopic texture after an external AC electric field is applied. (d) A prototype display on glass substrates. The difference in color in the background is the result of slight non uniformity in the cell thickness.

Image of FIG. 3.
FIG. 3.

Transmittance-voltage characteristics of a homeotropic cell filled with nematic LC possessing negative dielectric anisotropy. The vertical arrows indicate the voltages that correspond to 10% (OFF state) and 90% (ON state) of the maximum transmission. The inset shows the switching time characteristics of the same cell between the ON and OFF states.

Image of FIG. 4.
FIG. 4.

A prototype alphanumeric 2 in. × 3 in. flexible display made using polyethersulphone substrates (a) in flat geometry (no mechanical strain) (the lower left electrode segment of the first “8” is partially damaged) and (b) wrapped around a cylindrical object of 1.25 in. radius with its axis in the vertical direction.
