Disclosed herein are sealed devices comprising a first substrate, a second substrate, an inorganic film between the first and second substrates, and at least one weld region comprising a bond between the first and second substrates. The weld region can comprise a chemical composition different from that of the inorganic film and the first or second substrates. The sealed devices may further comprise a stress region encompassing at least the weld region, in which a portion of the device is under a greater stress than the remaining portion of the device. Also disclosed herein are display and electronic components comprising such sealed devices.

The present invention discloses a vacuum glass component, wherein the vacuum glass component is formed by compounding two or a plurality of glass plates, and the peripheries of the two or a plurality of glass plates are sealed with each other through sealing part in air-tight manner, a gap remains between the sealing part and the edge of the glass plate, vacuum-pumping is performed between adjacent glass plates at the inner side of the sealing part, and the sealing part is isolated from the outer environment between adjacent glass plates at the outer side of the sealing part by filling seal gum, resin or plastic. The vacuum glass component make the outer side of the sealing part isolated from the outer environment by using seal gum, resin or plastic, thereby preventing the metal at the sealing part from forming a heat bridge and facilitating the later installation and use of vacuum glass component. Moreover, the surface at the side edge of the vacuum glass component can be trimmed to be parallel and level by setting seal gum, resin or plastic, thereby keeping the beautiful appearance of the vacuum glass component.

High energy density multi-layer capacitors comprise inner electrodes buried within thin layers of alkali-free glass. The multi-layer glass capacitor can be fabricated by heating a plurality of capacitor layers above the annealing temperature of the glass to thermal bond the layers together. The edge margin of the buried electrodes can be selected to provide an adequate protection level from high-voltage flashover of the multi-layer glass capacitor. For example, an edge margin of 0.125″ can hold off about 10 kV in air.
