    Abstract: Selective erasing capability is provided in a display system having a photochromic member upon which information is written by an electron beam which addresses a selected portion of a phosphor layer. Light from the addressed portion of the phosphor changes the optical density of the photochromic glass. The information is selectively erased from the photochromic member by light from a gas plasma panel having gas-filled cells. These cells emit predominantly infrared light which bleaches the photochromic glass to erase the information. The gas plasma panel is maintained at a threshold of excitation by an applied AC voltage. Specific cells are addressed by light from the phosphor layer. The electron beam selects a portion of the phosphor layer and light from this portion selectively excites the desired cell, or cells.
