ELECTRO-OPTICAL MATRIX DISPLAY
Abstract
Preparation of RIS 1 films with low coercive force and good display properties is readily achieved, and continued efforts have been made toward further improvement of display element properties and reproducibility. The problem of immobilization of the bitter colloid in an unswitchable display pattern has been investigated by modifying the preparation of colloid dispersions, and by providing protective overlayers on the magnetic films. Recent non-aqueous suspensions in glycerine appear to be a solution to immobilization; other aqueous suspensions also show promising freedom from immobility over long periods. Protective coatings consisting of 3 layers of SiO of 800 A, total thickness, appear effective in protecting films against corrosion and immobilization. Continued refinement of seals, spacers, and filling techniques is in progress, although workable sealed modules can be readily made at the present state of development.
