Colloidal suspensions in glycerine and glycol-type solvents have been developed which have long term freedom from immobilization, and appear to simplify many aspects of module fabrication. Immobilization behavior observed is attributed in large part to spacing problems, both in non-aqueous and aqueous solvents. New substrate holders and heaters have been constructed to evaporate films over the entire substrate and chromium underlayers are currently in use to increase film adhesion. A cover glass containing internal spacers and sealing surface fabricated by etching with HF has been developed and should simplify spacing and sealing problems. Amplifiers were constructed to drive display elements in AC pulse writing mode, and necessary modification and testing is in progress. Design of the demonstration model to be delivered is in progress and consideration is being given to requirements of illumination and electronics to produce a completely selfcontained unit. Author
