Method and apparatus for electronic switching of a reflective color display |
摘要 |
A light modulating apparatus comprising a liquid crystal light modulating material confined between substrates, elongated electrically-conductive paths supported on opposite sides of the light modulating material by the substrates and a pair of gating systems for supplying voltage pulses to the electrically conductive paths for addressing the light modulating material is disclosed. The light modulating material includes polydomains of polymer network dispersed in a chiral nematic liquid crystal having positive dielectric anisotropy. This material is confined by the substrates between inner surfaces treated to promote homogeneous alignment of the liquid crystal near the inner surfaces. The apparatus provides energy efficient passive control of a bistable light modulating material.
