Abstract
The utility model discloses a small size color picture tube, which comprises a glass screen. The front end of the inner part of the glass screen is provided with a shadow mask, the back part of the glass screen is connected with a glass cone, the back end of the glass cone is sheathed with a deflection coil, the back part of the deflection coil is connected with an electron gun, the angle of deflection can be 90 degrees or 110 degrees, and the shadow mask is provided with circular through holes. The color picture tube disclosed by the utility model has the advantages of small dimension, high definition and good visual effects.
Description
Technical field
The utility model relates to a kind of color picture tube, relates in particular to the color picture tube that a kind of small portable color television set uses.
Background technology
The color picture tube that uses in the present television set is generally more than the 37CM, and it is rational in infrastructure, technical maturity, and definition is good, and the life-span is longer, is accepted by vast consumer.But the color picture tube that in the small size television set, uses (below the 37cm), the technology prematurity, structure is not quite reasonable, specifically have the following disadvantages: the deflection angle of existing small size colorful visualization tube glass cone is 55 °, make picture tube longitudinal ruler modest ability to be unfavorable for the miniaturization of television set, what adopt on the shadow mask in addition is the stripe shape aperture, cause the phosphor strip pitch big, resolution is low.
Summary of the invention
Small size color picture tube resolution is low in order to solve, the shortcoming of poor visual effect, and the purpose of this utility model is to provide a kind of small sized colour picture tube of high definition.
The technical scheme that the utility model adopted is: comprise the glass screen, the interior forward end of glass screen is installed shadow mask, and the back of glass screen connects the glass awl, the rear end socket deflecting coil of glass awl, the back of deflecting coil connects electron gun, and the deflection angle of glass awl is 90 ° or 110 °, is covered with manhole on the shadow mask.
The beneficial effects of the utility model are: because the deflection angle of glass awl adopts 90 ° or 110 °, shortened the longitudinal size of color picture tube, whole overall dimension is diminished.Use manhole on the shadow mask, improved the assortment of electron beam and phosphor strip, it is more reasonable that it is arranged on whole face, improved resolution greatly, improved definition.
