Cathode ray tube electron gun having cold cathode emission network transmitting electron beam assembly and mechanism zone converging micro beams two points.

摘要

The electron gun tube has a cold cathode emission network transmitting an assembly of electron beams. An extraction electrode with pierced holes is placed above the cathode. A collimator electrode reduces the emission angle of the micro beam. The gun has a mechanism (23) converging micro beams into a zone (40) such that the micro beams converge onto two zone points (Ox,Oy).
