PURPOSE:To realize observation of display from both sides by employing a transparent electrode as the anode of phosphor display panel and arranging a grid and anode respective to both sides of filament. CONSTITUTION:The hot electrons emitted from a filament 1 is controlled by grids 2, 2' and collides with phosphors 3, 3'. The phosphors 3, 3' are stuck on the anode electrodes 5, 5' formed on glass substrates 4, 4'. In order to form a vacuum vessel, the glass substrates 4, 4' are sealed by a selaling material through a side plate 8. Each electrode is extended to the outside by lead wires formed on the glass substrate and is connected to the lead 7, 7'. Luminous condition of phosphor can be observed through the anode electrode by forming it with transparent conductive film made of tin oxide indium oxide or with mesh type metal thin film etc. |
