Polymer-stabilized amorphous STNLCDs using one-side rubbing

A new LCD device called Polymer Stabilized Amorphous (PSA) STNLCD was prepared by one-side rubbing technique and adding a low percentage of a polymer dopant into the cell by curing the photopolymers under the application of an electric. It's shown to introduce a LC polymer network. A wide viewing angle characteristics and reduction of driving voltage have been demonstrated. Comparing with the conventional one-side rubbing STNLCD, the PSA-STNLCD has more stability and adapt to mass production.
