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.

Cathode ray tube having a scatter-proof band

A deflection yoke for a cathode ray tube improves assembly and productivity and enables effective control of magnetic field corrections during device processing. The deflection yoke includes a horizontal deflection coil located next to the outer circumference of a funnel to generate a horizontal magnetic field, and a vertical deflection coil installed at the outer circumference of the funnel to generate a vertical deflection magnetic field. The vertical deflection coil is insulated from the horizontal deflection coil. A ferrite core is located close to the vertical deflection coil to reduce the loss in the magnetic force generated from the horizontal and vertical deflection coils, and to enhance their magnetic efficiency. A correction unit is spaced apart from the horizontal deflection coil by a predetermined distance to correct a geometric distortion of the vertical and the horizontal deflection magnetic fields that is generated due to the vertical and horizontal deflection coils.

Deflection yoke for cathode ray tube

A Cathode Ray Tube (CRT) includes a panel having an inner phosphor screen, a funnel connected to the panel and adapted to have a deflection unit arranged thereon and a neck connected to the funnel and having an electron gun arranged therein. A shatter-proof member is installed on the funnel to prevent the tube from shattering.

A cathode ray tube includes a panel with a sealing surface, and a funnel with a sealing surface contacting the sealing surface of the panel. The panel and the funnel each have a thickness varied at the sealing surface thereof.

Cathode ray tube

An image display device includes a cathode ray tube. The cathode ray tube includes a panel with an inner phosphor screen, and a funnel connected to the panel with a cone portion mounting a deflection unit on the outer circumference thereof. A neck is connected to the funnel while mounting an electron gun therein. The interface between the cone portion and the neck is called a neck seal line, and the portion of the electron gun sealed to the neck called a gun sealing portion. When the distance between the panel and the neck seal line is indicated by A and the distance between the neck seal line and the gun sealing portion by B, the values of A and B satisfy the following conditions:0.31&#x3c;&#x3c;0.38 and79 mm&#x3c;&#x3c;95 mm.
