Abstract of the Disclosure, Two color write-through information displayed by a direct-viewing bistable storage tube is achieved by admixing particles of a storage phosphor with surface-killed particles of a different phosphor to form a dielectric layer on a conductive layer having an array of collector electrode members. The collector electrode members are formed from surface-killed conductive phosphor particles. The storage phosphor and surface-killed phosphors operate at different voltage levels to simultaneously display storage and write-through information in three different colors.
