Abstract

PURPOSE: To simplify structure and improve display performance by observing the level display which is luminously displayed outside a transparent substrate on which cathode electrodes and fluorescent devices are provided.
CONSTITUTION: Preset clock pulses are applied to the cathode electrode 2 and the preset positive voltage is applied to the anode electrode 4 for the time corresponding to the signal level to be displayed. In the desired display section of a level meter, discharge occurs between the anode and cathode electrodes 4 and 2. In this case, ultraviolet rays occur near the cathode electrode 2 and two fluorescent devices 5 arranged near the cathode 2 are excited. As a result, the fluorescent device 5 emits light and the signal levels are displayed.
