The invention is a cathode-ray tube (CRT) and method of manufacturing the CRT having a contrast enhancing coating on the exterior surface of the viewing faceplate. The contrast enhancing coating reduces the transmission of faceplate of the CRT by about 50%. The coating also yields gloss values in the range of 70 to 90. The manufacture comprises the steps of preparing an intermediate formulation containing a hydrolyzed organic silicate, diluting the intermediate formulation with an organic solvent and adding a contrast enhancing material to provide a final formulation, spraying the final formulation onto the faceplate to form the coating, heating the faceplate to cure the coating, and rinsing the coating, thereby forming a stable contrast enhancing coating on the faceplate.

A method and apparatus of maintaining spacing between tension focus mask strands in a tension focus mask. The method includes providing a tension focus mask comprising busbars with crosswires connected therebetween. A permanent adhesive is applied to the screen-side of the mask strands. Next, novel non-permanent horizontal guide members are attached to the gun-side of the mask strands, where an adhesive is applied to the guide member before the guide members are applied to the mask. The guide members maintain the vertical mask strand spacing during: (1) the application of the horizontal crosswires to the screen-side of the mask and (2) the subsequent thermal processing. The thermal processing cures the adhesive on the screen-side of the mask, thereby: (1) permanently attaching the crosswires to the mask strands and (2) volatilizing the adhesive on the gun-side of the mask strands such that the non-permanent guide member detach from the mask strands.

The present invention provides a focus mask and frame assembly for a cathode ray tube. The cathode ray tube includes an evacuated envelope enclosing a luminescent screen, a focus mask, and a support frame having at least two long sides for supporting the focus mask between the electron gun and the screen within the cathode ray tube. The focus mask has an active array area formed of a plurality of strands and cross wires separated by an insulating material and defining a plurality of focusing apertures within the array area. A border is attached to the strands opposite the insulating material along the upper and lower outer edges of the active array area. The borders extend into the active array area such that the cross wires overlie a portion of the borders and the borders form focusing apertures with the strands along the upper and lower edges of the array.

The present invention provides an improvement in a color picture tube having a tension mask supported by a support frame mounted within said tube. The mask has a significantly lower coefficient of thermal expansion than the frame. The frame has two substantially parallel cantilevered members, each member has a distal edge to which the tension mask is attached. At least one of the distal edges has two sections separated by a gap therebetween. The two sections include an inner section and an outer section. The mask is glued to the inner section and is welded to the outer section.

A display apparatus comprises a CRT having an evacuated envelope including a faceplate with a luminescent screen on the interior surface thereof. An electron gun is disposed within a neck of the envelope for generating and directing at least one electron beam toward the screen. A funnel connects the neck of the envelope with the faceplate. A deflection yoke is disposed around the envelope at the junction of the neck and the funnel. The yoke is attached to the envelope with an adhesive. The envelope further includes a first conductive coating on the interior surface of the funnel, a second conductive coating on at least a portion of the exterior surface of the envelope, and a third coating on the exterior surface of the envelope underlying the yoke and connected to the second conductive coating. The third coating provides a resistive, adhesive-primer coating that acts as a barrier between the yoke adhesive and the envelope and has a composition consisting essentially of a polychloroprene latex, a conductive filler material selected from the group consisting of carbon black and graphite, and water.

A cathode ray tube has an envelope () including a panel () and a neck () connected by a funnel (). The funnel comprises a main body portion () having a seal edge () and a neck. The main body portion has at least one region with a higher tensile stress than other regions of the main body portion. An exterior surface of the main body portion has first and second protective coatings (). The first protective coating () covers at least a portion of the at least one region. The first protective coating is of a composition and thickness such that the first protective coating substantially reduces the susceptibility of the at least one region from incurring mechanical damage. The second protective coating () covers at least a portion of the first protective coating and is of a composition and thickness such that the second protective coating protects the funnel from moisture contact.

A resistive spacer coating for a carbon nanotube (CNT)/field emission device (FED) display is described. The resistive spacer coating reduces electrostatic charging of the spacer during operation of the display while maintaining the field potential between the cathode and the phosphor screen. The resistive coating includes one or more resistive materials which are combined with binders that are then applied to the spacer.

A display screen of a color display is disclosed (see FIG. ). The display screen includes a glass plate having an array of three different color-emitting phosphors thereon. A graphite-based matrix is placed in the interstitial regions between each of the three different color-emitting phosphors. The graphite-based matrix is formed from an aqueous composition including graphite, potassium silicate and sodium silicate.

The present invention relates to a bake-hardenable solution that is electrically conductive, when hardened. The resultant conductive panel coating 38 is utilized for electrically interconnecting a metal stud 27 embedded in a sidewall 20 of a faceplate panel 12 of a CRT 10 to a conductive layer 24 overlying a luminescent screen 22 on an interior viewing surface of said faceplate panel 12. The solution consists essentially of the following ingredients: glass frit powder; graphite; organic binder; solvent; and a material to enhance the porosity of the resultant conductive panel coating 38.
