Abstract:
A novel CRT and method of making the CRT are disclosed. The CRT comprises an internal neutral density filter that lies between the phosphor deposits and the interior surface of the faceplate panel. The filter enhances the contrast of the CRT without compromising center to edge brightness ratio of the CRT. The filter comprises very fine particles, wherein the particles are black, gray, or a mixture of black and gray. The filter reduces the absorption of the faceplate by 25 to 75%. The invention is particularly useful for substantially flat CRTs. The method of producing the novel CRT comprises the steps of preparing a suspension of well-dispersed light-absorbing, carbon-containing particles which are 0.05 to 2 microns in aqueous media and applying the suspension onto the interior surface of the faceplate panel prior to applying at least one phosphor deposit. The suspension may also include suitable organic and inorganic binders and dispersing and wetting agents.

Abstract:
Differently sized silicon nanoparticles are used as a phosphor material for cathode ray tubes, field emission displays, or liquid crystal displays. The differently sized particles will emit different light wavelengths, such as red, green, and blue. Thus, the same material can be used for all three phosphors.
Abstract:
A heat absorbing film (14) made of an oxide is formed on a conductive reflecting film (13) by applying and baking a sol containing a material, which is to form the oxide, in a colloidal state. Conditions under which a vacuum evaporation system for forming the conductive reflecting film (13), and an applying/baking system for forming the heat absorbing film (14) are operated need not be changed, and the heat absorbing film (14) having small variations in thickness and quality can be formed on the conductive reflecting film (13). Reflection and radiation of heat from the conductive reflecting film (13) to a color selection electrode are suppressed effectively, so that a color cathode-ray tube in which a decrease in color purity is small can be manufactured.
Abstract:
The invention relates to a method for the cooling of a cathode ray tube panel, in which a heat radiation controlling means is provided at a small distance from the panel, on either side of the panel, and parallel to the panel surface. Said means comprises a first area with a high reflectivity for heat radiation, which first area is near the center of the panel, and said means comprises a second area with a high absorption for heat radiation, which second area is near the edges of the panel. The result of this measure during the cooling of a panel is a more even temperature distribution over the surface of the panel. In particular, the temperature gradient between center and edge of the panel is reduced. Because of the glass wedge of (Real) Flat panels the center of the panel is thinner than the edge of the panel. The thinner part will normally cool down faster because of the lower heat capacity. Local temperature differences over the surface of the panel during cooling down will lead to so-called nullmembranenull stresses. The method of the invention will minimize these stresses.
