Abstract
A cathode ray tube includes a bulb having a screen, a conductive layer coated on the inner surface of the bulb, an electron gun mounted in the neck portion and having a final accelerating electrode electrically connected to the conductive layer, and leakage current shielding means installed in the neck portion, for shielding leakage current flowing along the inner surface of the neck portion from the conductive layer.
Claims3
A cathode ray tube, comprising:
- a bulb having a screen and a neck portion;
- a conductive layer coated on an inner surface of the bulb;
- an electron gun mounted in the neck portion and having final accelerating electrode
- electrically connected to the conductive layer;
- and
