The invention
The disclosed invention relates to shielding a CRT user from
electromagnetic radiation. Specification at 1. With reference
to Figure 2, the invention is concerned with radiation 8b leaking
around the edge of a shadow mask 5. Shield 4a is placed to stop
such radiation from exiting out the front of CRT housing 3. An
alternative embodiment is shown in Figure 5. In addition to
being formed on the CRT’s front surface as in Figure 2, the
shield 4b in Figure 5 is also formed on the CRT’s side surfaces.
Specification at 15, lines 2-5.
The prior art
Dougherty is concerned with shielding a CRT from external
interference. Figure 2A shows a shield 48 and 30 which shields
the CRT’s electron beams from stray magnetic flux transverse to
the tube axis. Column 7, lines 6-10. The stray flux is shown as
flux 54, 56, 58, and 60 in Figure 2A.
Suehiro is concerned with shielding a CRT from external
interference and providing an anti-explosion band to prevent
