• H01J 31/3 having regulation of screen potential at anode potential, e.g. iconoscope
• H01J 31/34 having regulation of screen potential at cathode potential, e.g. orthicon
• H01J 31/4 having grid-like image screen through which the electron ray passes and by which the ray is influenced before striking the output electrode, i.e. having "triode action"
