Title:
COLD CATHODE UNIT
Document Type and Number:
Japanese Patent JPS5282071
Kind Code:
A
Abstract:
A cathodoluminescent image display device utilizes a cold cathode as the source of electrons. The cold cathode comprises a photocathode, an electron multiplier and a fluorescent anode. The structure of the cathode is such that a portion of the light given off by the fluorescent anode is free to feedback and impinge upon the photocathode. The cold cathode disclosed herein is thus a closed loop device having a loop gain G. The electron multiplier has a gain Gm such that the loop gain G of the device is maintained at a value greater than or equal to one thus causing a sustained electron discharge.
