Abstract
The laser cathode ray tube has a laser screen; a focusing system for focusing the electron beam on the laser screen; a deflection system for deflecting the electron beam; and at least two electron guns with cathodes for generating at least two electron beams focused simultaneously on one and the same laser screen element defined by the deflection system.
Claims20
A laser cathode ray tube comprising:
- a laser screen;
- a focusing system for focusing at least two electron beams simultaneously on one point on the laser screen;
- a deflection system for deflecting the at least two electron beams;
- and
- at least two electron guns each with a cathode for generating the at least two electron beams.
A laser cathode ray tube comprising:
- a glass bulb;
- a deflection system installed outside the glass bulb;
- a screen mounted on the end face of the glass bulb;
- a plurality of electron guns installed inside the glass bulb, each of the guns having a cathode, for generating a plurality of electron beams focused simultaneously on one point of the screen under the control of the deflection system;
