Abstract

Improvements in imaging devices, characterized in that said devices comprise a formation of gas-filled cells; a volume of liquid crystal material in operating relationship with said cells; and electrode means in operating relation to said liquid crystal volume and said cells, whereby, when said cells are turned on and discharged, potentials can be fed to cause currents to flow from said lit cells through corresponding volumes of said liquid crystal material, changing the optical characteristics thereof, whereby a message presented by said cells can be presented by said volume of liquid crystal material.
