Display device having fire-retardant shield case

A device comprising:

• a front case;
• a cathode ray tube mounted on said front case;
• a main circuit board mounted on a rear side of said cathode ray tube;
• a circuit board frame, mounted to said front case, to support said main circuit board;
• a nonflammable and fire-retardant shield case encasing said cathode ray tube and said main circuit board, to contain a fire if the fire occurs in an interior of the display device, while providing a shielding effect which minimizes radiation of electromagnetic waves generated by said cathode ray tube and protects said cathode ray tube from external electromagnetic interference;
• a rear case to connect with said front case to encase said cathode ray tube, said main circuit board, said circuit board frame and said shield case;
• protrusions formed on an inner surface of said rear case;
• and
• a plurality of case mounting holes formed in a surface of said nonflammable and fire-retardant shield case, corresponding to said protrusions.

A display device comprising:

• a cathode ray tube;
• a main circuit board mounted on a rear side of said cathode ray tube;
• a circuit board frame to support said main circuit board;
• a nonflammable and fire-retardant shield case as defined in Underwriter's Laboratory Standard 1418 (1992), Standard for Safety for Cathode Ray Tubes, to provide a shielding effect to minimize radiation of electromagnetic waves generated by said cathode ray tube and protects said cathode ray tube from external electromagnetic interference, and to contain a fire if it first occurs at said cathode ray tube or said main circuit board;
• and
• an outer case encasing said cathode ray tube, said main circuit board, said main circuit board frame and said shield case.
