Laser cathode ray tube

A laser CRT includes a cathode, a modulator having an orifice for forming an electron beam from the electrons emitted by the cathode, and a beam directing unit directing the electron beam formed by the orifice of the modulator to the laser screen of the laser CRT. To reduce the diameter of the elect...

Beschreibung
Zusammenfassung:	A laser CRT includes a cathode, a modulator having an orifice for forming an electron beam from the electrons emitted by the cathode, and a beam directing unit directing the electron beam formed by the orifice of the modulator to the laser screen of the laser CRT. To reduce the diameter of the electron beam and to thereby improve the resolution of the laser CRT, the laser CRT includes at least one other modulator having an orifice for forming another electron beam from the electrons emitted by the cathode, the beam directing unit being adapted for directing the other electron beam formed by the at least one other modulator to the laser screen.
