Abstract

We have characterized the mechanical stability of the Pixel-Isolated Liquid Crystal (PILC) mode for plastic LC display applications. In our device, the LC molecules are fully isolated in the pixels by the phase-separated polymer walls. The experimental results of microscopic observation and electro-optic characterization show that our flexible PILC device has good mechanical stability against external point pressure or bending distortion due to the polymer walls in our structure.
