摘要:
An airtight envelope for an FED capable of ensuring formation of a gap or internal space therein with high accuracy and preventing leakage thereof and a decrease in display area. An anode substrate having a phosphor-deposited display pattern formed thereon and a cathode substrate having an electron emission source formed thereon are sealed joined to each other using a sealing material, to thereby provide an airtight envelope for an FED. The substrates are provided at a portion thereof joined together with particulate or bar-like elements which are kept unmelted or substantially unsoftened. Also, spacers are arranged at positions in a gap between the anode substrate and the cathode substrate which do not interfere with a display by the FED.
摘要:
A vacuum envelope capable of preventing contamination of an electron source and deterioration of luminous characteristics of a phosphor layer. Electrons emitted from a tip end of emitter cones are accelerated by an anode conductor to which a positive voltage is applied with respect to a gate conductor, to thereby impinge on the phosphor layer, leading to luminescence of the layer. The luminescence is observed through a transparent anode substrate. Spacers are bonded at only one end thereof to a cathode substrate by means of seal glass, to thereby keep the seal glass from being irradiated with electrons.

A strut aligning fixture capable of improving misregistration of struts arranged between two glass plates for a vacuum glass envelope to hold the glass plates spaced from each other at a predetermined interval. An alignment plate is formed of a first alignment plate member of a small thickness and a second alignment plate member of a large thickness by lamination. The first alignment plate member is provided with strut holes, which can be formed with high accuracy because of a reduced thickness of the first alignment plate member. The alignment plate is used as a fixture for arranging the struts in the vacuum glass envelope while minimizing misregistration of the struts.

A process for manufacturing a transparent conductive film wiring board capable of being practiced according to a dry procedure to simplify the manufacturing and reduce the manufacturing costs. First, a SiO.sub.2 layer is provided on a substrate and then a black ITO film is formed on the SiO.sub.2 layer. The black ITO film is subject to processing using laser emitted from an output horn, resulting in being cut into a predetermined wiring pattern. Metal evaporated by laser processing is sucked by a vacuum suction head. Then, the substrate is subject to calcination to oxidize and crystallize the black ITO film 3 of the wiring pattern to form a transparent ITO film of the wiring pattern.

An automatic support pillar transfer mechanism is provided that enables an enlarged transfer range, reduced produce failure and mass-production. The touch sensors 17a to 7c are arranged on the moving section 12 to measure the plane orientation of the surface of the jig 7. The jig adjusting section 6 is driven based on the measurement results on the plane orientations of surfaces of the jig 7 to adjust the surface of the jig 7 in parallel. With plural support pillars 15 sucked and held at predetermined intervals by the jig 7 adjusted in parallel, the bonding agent coated substrate 14 attached on the moving section 12 is descended to coat the bonding agent 13 onto the one ends of the support pillars 15. The substrate 16 to which the support pillars 15 are transferred is attached to the moving section 12. Variations in plane orientation of surfaces of the substrate 16 are respectively measured by means of the touch sensors 5a to 5c. The jig adjusting section 6 is driven according to the variations in plane orientation of the surfaces of the substrate 16. With the surface of the jig 7 arranged in parallel to the surface of the substrate 16, the moving section 12 is descended to transfer the support pillars 15 onto the surface of the substrate 16.
摘要:
A hermetic container which can improve its stress resistance and its buckling strength and prevent deformation due to the atmospheric pressure. The space between the anode substrate and the cathode substrate in the hermetic container can be stably maintained. Anode conductors and fluorescent substance layers are formed on the inner surface of the anode substrate. Electron sources are formed on the inner surface of the cathode substrate so as to confront the corresponding display portions on the anode substrate. In order to complete a container, the anode substrate is spaced from the cathode substrate a predetermined distance apart and the fringe portions of the substrates are sealed. A supporting member is disposed in the container. The supporting member 15 consists of a plate in which plural through holes are formed at predetermined intervals and reinforcing supports which are respectively inserted into the through holes of the plate and of which the middle portions are bonded at the inlets of the through holes. Each reinforcing support has one end in contact with an inner surface of the anode substrate and the other end in contact with an inner surface of the cathode substrate. Each reinforcing support maintains the gap between the anode substrate and the cathode substrate at a fixed distance.

A vacuum airtight envelope capable of being manufactured in bulk and with increased yields. Cathode substrates and anode substrates are prepared by multisubstrate co-formation techniques. A cathode source plate is cut into a plurality of individual cathode substrates, which are mounted on an anode source plate by surface-mounting. Then, getter boxes are temporarily fixed on the anode source plate and then sealedly joined thereto together with cathode substrates. Then, the anode source plate is cut, to thereby provide individual envelopes, which are then evacuated to a vacuum.
摘要:
A field emission type fluorescent display device capable of carrying out luminous display with increased reliability at an anode voltage 200V to 1000V and providing a desired luminous color by means of a filter. The fluorescent display device includes a luminous display section consisting of three display elements. The display elements include filters of red, green and blue colors on which light-permeable anode conductors are deposited, respectively. Then, the anode conductors have phosphors of the same colors as the filters deposited thereon, respectively. The blue phosphor is made of ZnO:Zn substantially containing a blue color component. Thus, a combination of the blue filter and phosphor provides light of a blue color with increased efficiency.
摘要:
A method of making an envelope for a display device is capable of permitting positioning and fixing of glass beads acting as spacers to be carried out with high precision and increased strength, respectively. Liquid for forming photoadhesive photosensitive film is applied to a substrate. The substrate is exposed to light through a mask to cause portions of the film on which glass beads are to be fixed to exhibit adhesion. Glass beads coated with glass frit of a low softening point are applied to the substrate and unnecessary glass beads other than those applied to the above-described portions of the film are removed. Subsequently, a casing is arranged on the substrate and calcination is carried out. This results in the photosensitive film volatilizing and the glass beads being adhered to both a flat plate and the substrate.
