Abstract
A cathode ray tube includes a tube having a panel having an inner phosphor screen, a funnel connected to the panel, a neck connected to the funnel, a deflection unit disposed around the funnel, an electron gun installed in the neck, and a scatter-proof unit installed on the panel and the funnel such that the panel shares the scatter-proof unit with the funnel for preventing the tube from breaking and scattering into many pieces.
Claims15
A cathode ray tube having a panel and a funnel coupled to a rear side of the panel, the cathode ray tube including a scatter-proof unit formed around a portion of said panel and a portion of said funnel, said scatter-proof unit having a total width Wp+Wf, where Wp is the width of a portion of the scatter-proof unit formed around the panel and Wf is the width of a portion of the scatter-proof unit formed around the funnel, such that the condition 0.03≦Wf/(Wp+Wf)<0.35 is satisfied.
A cathode ray tube having a panel and a funnel coupled to a rear side of the panel, the cathode ray tube including a scatter-proof unit formed around a portion of said panel and a portion of said funnel, said scatter-proof unit having a total width Wp+Wf, where Wp is the width of a portion of the scatter-proof unit formed around the panel and Wf is the width of a portion of the scatter-proof unit formed around the funnel, such that the condition 0.08≦Wf/(Wp+Wf)<0.27. is satisfied.
A cathode ray tube having a panel and a funnel coupled to a rear side of the panel, the cathode ray tube including a scatter-proof unit formed around a portion of said panel and a portion of said funnel, said scatter-proof unit having a total width Wp+Wf, where Wp is the width of a portion of the scatter-proof unit formed around the panel, Wf is the width of a portion of the scatter-proof unit formed around the funnel, Wp>Wf and Wf/(Wp+Wf) is 0.166.
