Abstract
The high-definition color display tube consists of three electronic guns in different size and shape and corresponding color filter disks. It features the bowl-shaped G gun, the ring groove shaped R gun and B gun around the G gun, and the coincidence of the three axes. Unlike available color display tubes, which have large pixel diameter and non-coincident tricolor raster, the color display tube of the present invention may be used widely in TV set.
Description
The TV industry that the present invention relates to, a kind of specifically picture tube that improves the color television set definition.
Why the definition of existing color picture tube is not as black and white picture tube, and its main cause is that color picture tube is the three electron-beam pipe, and three electron beams do not penetrate from an angle.Scan line is discontinuous on phosphor screen in addition, and each pixel is formed by GRB three-color phosphor point, so cause the pixel diameter to increase, the three primary colors grating such as can not overlap fully at reason, so cause more than low 200 lines of definition than unidimensional black and white pipe.
The objective of the invention is: design a kind of new type colorful picture tube, make its resolution capability exceed 200 lines and be up to more than 600 lines than existing colored picture tube.Make image more clear.
Technical scheme of the present invention is: a kind of high-definition color picture tube is to make different sizes and shape by three electron guns (shadow-mark pipe) of colored picture tube, constitutes by corresponding colour filter.Its special character is: G electron gun (shadow-mark pipe) is made bowl-shape, R electron gun and B electron gun are then made the annular ditch shape, and it differs in size, and is looped around the periphery of G electron gun (bowl-shape) successively, three's axis coinciding.The electron beam of ditch shape annular rifle penetrates from periphery uniformly.The three primary colors electron beam of colour TV signal is penetrated from an angle (plane), and directly the impact fluorescence screen saves the shadow mask plate and the colour bar increase colour filter that have colored picture tube now.As: what certain G electron gun of the same colour (bowl-shape) penetrated is a solid line, (R) top of look then is hollow taper light beam, just in time overlap the periphery of light beam inside, (B) look also is that taper is hollow at outermost then, be enclosed within the periphery of R look again, this dichromatism taper light beam has constant slope, though the external diameter at top is to strengthen in proper order, but must guarantee during to terminal point that three looks can be gathered into the bright spot of same diameter (pixel), the i.e. pixel level of black-and-white TV.Deflection and focus circuit in addition then will have the direct scanning black-white phosphor screen of light beam of three mixture of colours, and color display make its resolution capability reach 600 lines, makes image bright-coloured more true to nature.
Owing to adopt technique scheme can realize the high color picture tube of a kind of definition simple in structure.
Embodiment further specifies below in conjunction with accompanying drawing.
Fig. 1 is a principle front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is the dress row figure of electron gun of the present invention
In the drawings, 1 G electron gun, 2 R electron guns, 3 B electron guns, 4 deflecting coils
5 screens
As shown in the figure, G electron gun 1 (shadow-mark pipe) is made bowl-shape, 3 in R electron gun 2 and B electron gun are made the annular ditch shape, and it differs in size, and is looped around the periphery of G electron gun (bowl-shape) successively, three's axis coinciding.The electron beam of ditch shape annular rifle penetrates from periphery uniformly.The three primary colors electron beam of colour TV signal is penetrated from an angle (plane), and directly the impact fluorescence screen saves the shadow mask plate and the colour bar increase colour filter that have colored picture tube now.As: what certain G electron gun 1 of the same colour (bowl-shape) penetrated is a solid line, (R) top of look then is hollow taper light beam, just in time overlap the periphery of light beam inside, (B) look also is that taper is hollow at outermost then, be enclosed within the periphery of R look again, this dichromatism taper light beam has constant slope, though the external diameter at top is to strengthen in proper order, but must guarantee during to terminal point that three looks can be gathered into the bright spot of same diameter (pixel), the i.e. pixel level of black-and-white TV.Deflection and focus circuit in addition then will have the direct scanning black-white phosphor screen of light beam of three mixture of colours, and color display make its resolution capability reach 600 lines, makes image bright-coloured more true to nature.
Claims (1)
1, a kind of high-definition color picture tube, be to make different sizes and shape by three electron guns (shadow-mark pipe) of colored picture tube, constitute by corresponding colour filter, it is characterized in that: make G electron gun (shadow-mark pipe) bowl-shape, R electron gun and B electron gun are then made the annular ditch shape, it differs in size, and is looped around the periphery of G electron gun (bowl-shape) successively, three's axis coinciding.
