Applications Of Holographic Pdlc For Full Color Display

摘要

Both reflection and transmission modes of holographic polymer dispersed liquid crystal(HPDLC) have been demonstrated using a model formulation based on polyurethane acrylate. It was possible to make a set of HPDLC display devices covering the three primary colors by using a single mixture by simply changing the optical setup. In addition a full-color display of high color purity could be constructed by stacking the three HPDLC devices. We also demonstrated the image storage capability of the PDLC gratings using the same formulation.
