Embodiment Construction
[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0033] figure 1 It is a schematic side view showing the structure of the flat type cathode ray tube of the present invention.
[0034] exist figure 1 Among them, a cathode ray tube glass bulb (glass envelope) 1 is composed of a panel 2, a cone 3 and a tube neck 4.
[0035] The panel 2 has a front panel 2a and a rear panel 2b, and a fluorescent surface 5 is formed on the inner surface of the rear panel 2b.
[0036] On the other hand, an electron gun 6 is built in the neck 4 .
[0037] Furthermore, a deflection yoke 7 is mounted on the section from the neck 4 to the cone 3 .
[0038] In this flat type cathode ray tube, by deflecting electron beams 8 emitted from electron guns 6 by deflection yoke 7, an image is displayed on fluorescent surface 5 of rear panel 2b.
[0039] The display image (phosphor surface image) is observed from the direction indicated ...
