A cathode ray tube includes a panel in which a phosphor layer is formed, a funnel connected to the panel, the funnel including a neck having a region for housing an electron gun and a region to which a stem is sealed, and a stem having a plurality of stem pins, each stem pin being supported by each stem mound for applying voltage to each electrode of the electron gun. The inside diameter of the stem sealing region of the neck is greater than that of the electron gun-housing region, the diameter of an inner stem pin circle formed by interior stem pins disposed on the inside of the neck is less than that of an outer stem pin circle formed by exterior stem pins disposed on the outside thereof, a horizontal length between an outer edge of the stem mound and an interior of the neck is in the range greater than or equal to 1.0 mm and less than or equal to 2.0 mm. Furthermore, the cathode ray tube includes a panel in which a phosphor layer is formed, a funnel connected to and tapered from the panel, and a neck connected to the funnel and including an electron gun housing region and a stem sealing region, to which a stem having a plurality of stem pins arranged in an annular shape and passing therethrough for introducing signal voltages from an external circuit is sealed, where D is 22.5&plusmn;0.7 mm and D is in the range greater than D and less than or equal to 24.0 mm where the outside diameters of the electron gun-housing region and the stem sealing region are D and D , respectively.

Neck of funnel and stern sealed to neck of cathode ray tube

The periphery of a stem, which seals off the neck of a CRT and supports pins providing electrical current to some of electron gun's electrodes, is designed to contact either inner surface or outer surface of the neck end as well as the cross section thereof in order to prevent pores when the stem and the neck are fused together.

Cathode ray tube

A socket for interconnecting first and second lead pins fixed to a neck portion of a CRT at an array angle and to which a high voltage and a low voltage are applied, respectively, and a socket board including signal lines having an array angle different from that of the second lead pins, the socket including connector pins each having a pin holder portion connected to the second lead pin, an outer pin portion connected to the signal line, and an extension portion connecting the pin holder portion to the outer pin portion, and a socket main body to which the connector pins are fixed, wherein the array angle between the outer pin portions is the same as that between the signal lines.
