Abstract

Electron gun for cathode-ray tubes, comprising at least one cathode (23) based on field-effec microemitters, the microbeams of which converge on a region (40) in such a way that the two points of convergence of the microbeams in the horizontal and vertical directions are two separate points Ox, Oy in this region (40).
