Abstract
PURPOSE: To obtain a characteristic sufficient for visible rays, infrared rays or medical X-rays, by incorporating such element as photo-diode or transistor in semiconductor substrate.
CONSTITUTION: Voltage is applied on a filament 12 while another voltage more positive than that on said filament 12 is applied on the electrode 11 of anode substrate 2. Such voltage is also applied on the grid 13. When there are no incident visible or infrared rays from outer case, a plurality of photo-diodes composed of n- type semiconductor substrate 3 and p+-type semiconductor layer 5 formed to be arranged on main surface of substrate 3 in matrix are in reverse state thereby voltage isn't applied on each fluorescent member 10 and the light isn't emitted. While there are visible or infrared rays coming from outer case, current corresponding to the brightness flows through photo-diode thereby light is emitted from the fluorescent member 10.
