摘要： A cathode ray tube has an envelope (2) including a panel (3) and a neck (4) connected by a funnel (5). The funnel comprises a main body portion (16) having a seal edge (17) 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 (20, 21). The first protective coating (20) 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 (21) 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.

摘要： A flat panel display having a backplate structure (330), a faceplate structure (320), and a spacer (340) situated between the two plate structures is configured so that the electric potential field along the spacer approximates the potential field that would be present at the same location in free space, i.e., in the absence of the spacer, between the two plate structures. Consequently, the presence of the spacer does not significantly affect the trajectories of electrons moving from the backplate structure to the faceplate structures. Alternatively, the spacer is arranged to produce electron deflection that largely compensates for undesired electron deflection which occurs during earlier electron travel from the backplate structure to the faceplate structure. The net electron deflection is small.

摘要： A vacuum envelope of an image display apparatus includes a rear substrate and a front substrate opposed to each other and a sidewall interposed between the rear substrate and the front substrate. An image display surface is formed on an inner surface of the front substrate, and a large number of electron emitting elements that emit electrons toward the image display surface are arranged on an inner surface of the rear substrate. A grid is located between the rear substrate and the front substrate and fixed to the rear substrate. The grid has a thermal expansion coefficient higher than that of the rear substrate.

摘要： The present invention relates to an implosion prevention band (30) for a CRT (10). The CRT comprises an evacuated envelope (12) having a mask (35) and corresponding faceplate panel (14) with sidewalls (26) joined to a funnel (18). The faceplate panel and sidewalls form external corner surfaces and a peripheral inside blend radius (38). An implosion prevention band surrounds and closely hugs at least an edge of the external corner surfaces of the faceplate panel. The band extends along the exterior surface of the sidewall such that the width of the band is at or near the inside blend radius of the faceplate panel. The band is at or near the inside blend radius of the faceplate panel. The band is under tension to produce radially inwardly directed force components throught the corners of the faceplate panel and primarily near the blend radius to produce a high degree of implosion protection for the CRT.

摘要： A glass envelope for a cathode ray tube (10) and a method of production. The envelope comprises (12) a panel member having a thickness (t) that is defined by an equation which involves net tensile stress; wherein the panel having a net tensile stress not exceeding 1150 psi, having a surface compression induced during panel manufacture, and having an implosion protection band (30) shrink-fitted around a skirt (20) on the panel that augments surface compression in the panel (12), whereby the panel thickness is substantially less than that of a corresponding untreated tube envelope.
