Abstract: In a flat panel display device, a crack or burr is prevented from occurring by disposing a plurality of supports between adjacent connection members, and the supports are separated from the connection members by a predetermined distance. The flat panel display device comprises: a first substrate, including a plurality of active areas and a plurality of non-active areas; an emission unit disposed in the plurality of active areas; a second substrate connected to the first substrate; a plurality of connection members respectively disposed in the plurality of non-active areas and combining the first substrate and the second substrate with each other; and a plurality of supports disposed between the adjacent connection members so as to be respectively separated from the connection members, and supporting the first and second substrates, wherein the plurality of supports are separated from one another.

Abstract: In various embodiments, a discharge vessel for a high-pressure discharge lamp may include a plurality of parts from ceramic material, wherein the discharge vessel is made of at least two stacked layers.

Abstract: A polycrystalline body comprising aluminum oxide, magnesium oxide, hafnium oxide, and yttrium oxide in which alumina grains have an average size of at least 10 ?m and wherein the yttrium oxide is present in an amount of at least 6 ppm of the weight of the ceramic body, and the magnesium and hafnium oxides are present at a molar ratio of about 0.5:1 to about 3:1.

Abstract: A glass frame includes a cross-section that has a substantially polygonal profile with at least one re-entrant angle, and is intended to keep two plane substrates separate around their periphery. The frame may keep a space between two glass sheets, such as in the production of plane and hermetically sealed glass envelopes for use as field-emission screens.

Abstract: The present invention relates to an implosion prevention band for a CRT comprising an evacuated envelope having a mask and corresponding faceplate panel with sidewalls joined to a funnel. The faceplate panel and sidewalls form external corner surfaces and a peripheral inside blend radius. 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 under tension to produce radially inwardly directed force components through the corners of the faceplate panel and primarily near the blend radius to produce a high degree of implosion protection for the CRT.
