TH8213B - Color picture tube - Google Patents

Abstract

The exposed tube consists of an outer casing containing an electron gun, the outer casing is weather-sealed, a visor with a light transmission condition. And is placed on the front surface of the casing And a large number of red, blue and green dots are normally arranged inside the face plate, where the dot contains a phosphor layer and a color filter, where the phosphor layer is lighted by the radiation of the lobe. Cron A color filter is placed between the phosphor layer and the face plate, and where the green image dot has a color is placed in the The fourth quadrant of the coordinate system of the color system (L * a * b *), where a * is the horizontal axis and b is the horizontal axis and b * is the vertical axis when the light source's light. Standard C is reflected on the side. Outside of the face plate

Claims (6)

1. The color picture tube consists of chimney funnel which has a neck electron gun which was placed in the neck face plate with light conduction condition which is placed as the front surface of the cone, the cone and the face plate which is made up of the outer casing of such tubes to be sealed, airtight, and a large number of red, blue and green image dots normally arranged inside the faceplate. Where the image spot has a phosphor layer and a color filter, where the phosphor layer is illuminated. by the radiation of the electron beam Color filters are arranged between the phosphor layers. and that faceplate, and where the green dot has the color quality defined in the fourth quadrant. of the coordinate system of the color system (L* a* b* ), where L* represents brightness, where a* is the horizontal axis and b* is the vertical axis. When the light of the standard C light source is reflected on the outside of the faceplate 2. A color lamp as described in Claim 1, where the green dot has the color quality defined on it. Color system coordinate system(L* a* b* ), where L* represents light, where a* is the horizontal axis and b* is the vertical axis. which causes the following relationship to be answered b*<_(-8/3)a* 3. Color lamps as described in Claim 1, where the green dot has the quality of the color defined on it. Color system coordinate system (L* a* b*), where L* represents light, where a* is the horizontal axis and b* is the vertical axis. which causes the following relationship to be answered b*<_(-6/5)a* 4. The color picture tube consists of face plate with light transmission condition and effect textures for visualization. chimney cone, which is the front end of the chimney cone will be attached to the rear end of the face plate. The rear end of the cone is narrow. Such chimney cones are sealed airtight. with such a sheet It is the shell of the color picture tube. phosphor layer that is coated on the inner surface of the effective display surface of such faceplate, where such phosphor layer There will be a color phosphor corresponding to the red, blue and green image dots. Color filters are arranged between the sheets. and such phosphor layers and have a color cell that Corresponding to the red, blue, and green sight dots: and an electron gun positioned at the rear end of the cone. and was fined for electron beam radiation to the aforementioned phosphor layer corresponding to the display image. where the cells corresponding to the green fluorescent substance of the aforementioned color filter It consists of colored materials that It is a mixture of Fe2O3 particles and at least one selected from the group that contains the particles.
