Abstract:
A vacuum envelope of a flat display device comprises a rear substrate and a front substrate, located opposite to each other, and a seal portion which seals together respective peripheral edge portions of the front substrate and the rear substrate. A reinforcing portion has a core member harder than the sealing material and is provided outside at least a part of the seal portion. With use of the reinforcing portion, external force that acts on the peripheral edge portions of the substrates can be received by the reinforcing portion, so that external force that acts on the seal portion can be reduced considerably. If any external force is applied, therefore, the seal portion can be prevented from being dislocated or lowered in sealing properties.
Abstract:
A plasma addressed liquid crystal device (LCD) and its manufacturing method is disclosed wherein a second substrate is divided into segments which are connected at a joint. A third substrate is provided which includes a plurality of barriers formed thereon. The barriers are adhered to the second substrate by a gelled paste and the joints of the second substrate overlay the barriers. The joints and the barriers are fixed by the gelled paste so as to party absorb impacts from the second substrate.
Abstract:
Provided is an integrated gas discharge tube. In the integrated gas discharge tube, the structure of the gas discharge tube is regulated into an upper cover and an insulative base, and the internal side surface and the external side surface of the bottom surface of the insulative base are respectively subject to electrode integration, so that the discharge effect of the gas discharge tube is effectively increased and the preparation process and the preparation flow of a multi-terminal-to-ground gas discharge tube are greatly simplified so as to greatly simplify the preparation process and to realize batch production and high integration of the gas discharge tube. Also provided is a preparation method for an integrated gas discharge tube.
Abstract:
A vacuum envelope of an image display apparatus includes a front substrate and rear substrate opposing each other with a gap defined therebetween, and a frame provided between peripheral edges of the front substrate and rear substrate and attached in a sealed state to the front and rear substrates by a sealing material. The frame is formed by bonding a plurality of frame members, and includes at least two joints.
Abstract:
A flat display panel has a ventilation hole formed in a back glass substrate facing a front glass substrate with a space in between, and provides communication between the space and the exterior. A ventilation duct is connected to the ventilation hole and secured with a pressed frit to the outer face of the back glass substrate. The ventilation duct has a flange formed at one end thereof connected with the back glass substrate. The pressed frit having a ventilation hole is sandwiched between the flange and the back glass substrate, and fused to the flange and the back glass substrate in order for the ventilation duct to be secured to the back glass substrate.
Abstract:
A flat-panel display device having a transparent first plate and a second plate which are disposed in parallel with each other and cooperate to define therebetween an air-tight space in which light is generated for emission through the first plate, the display device including a sealing material for air-tightly sealing the air-tight space along a periphery of the first and second plates, and metallic thin sheets bonded with the sealing material to end faces of the first and second plates such that the metallic thin sheets cover the end faces. The display device is manufactured by applying the sealing material to the end faces such that a peripheral portion of the air-tight space is filled with a mass of the sealing material, forcing the metallic thin sheets onto the end faces such that the metallic thin sheets cover the end faces, and heating the sheets and the sealing material firing the sealing material for air-tightly bonding together the two plates while bonding the metallic thin sheets to the end faces through the sealing material.
