CUMULATIVE TWO PHASE DRIVE SCHEME FOR BISTABLE CHOLESTERIC REFLECTIVE DISPLAYS |
摘要 |
Bistable cholesteric liquid crystal material is disposed between opposed substrates, wherein one of the substrates has a first plurality of electrodes facing a second plurality of electrodes on the other substrate, wherein the intersection of the first and the second plurality of electrodes forms a plurality of pixels. The material is addressed by applying a preparation voltage across the first and second plurality of electrodes and then subsequently applying a selection voltage across the first and second plurality of electrodes. The material is then allowed to relax for a period of time, whereupon the preparation and selection voltages are reapplied. These steps are repeated until the liquid crystal material obtains the desired reflectance.
