ABSTRACT:
A display panel has an evacuated envelope with at least one transparent panel. Phosphor is deposited inside the panel at locations which are visible through the transparent panel. Two sets of electrodes are associated with the phosphor for locally controlling the brightness of the phosphor to give bright and dim displays, respectively, which are viewed through the transparent panel. The two displays are arranged to give a three dimensional appearance.
