Abstract:
A tetraode field-emission display and a method of fabricating the same are disclosed. A mesh is disposed between an anode plate and a cathode plate. The mesh has a gate layer and a converging electrode layer separated by an insulation layer to form a sandwich structure. The mesh has a plurality of apertures in correspondence with each set of anode and cathode. A glass plate is placed between the mesh and the anode to serve as a spacer. The converging electrode layer is facing the anode plate, such that the divergent range of an electron beam emitted by an electron emission source can be restricted. Thereby, the electron beam can impinge the corresponding anode more precisely.

A plasma display panel (PDP) with alignment structure. A first alignment pattern is disposed on a rear substrate and formed by a rib structure. A second alignment pattern is disposed on a front substrate disposed opposite, over the rear substrate and corresponds to a space defined by the first alignment pattern. The first and second alignment patterns are disposed outside of the display area of the plasma display panel.

An alignment mark for a plasma display panel (PDP). The alignment mark comprises a first and a second alignment patterns installed on a front and a rear substrate respectively. The second alignment pattern on the non-display area is simultaneously formed with the rib barrier formation on the display area of the rear substrate, wherein the second alignment pattern is hexagonal-honeycomb. The first alignment pattern on the front substrate is simultaneously formed with the non-transparent material fabrication, such as a bus electrode or black matrix fabrication, and corresponds to a space within the second alignment pattern. The first alignment pattern comprises at least one line segment, parallel to at least one side of the hexagonal honeycomb pattern on the rear substrate with a predetermined distance therebetween.
Abstract:
A method and an apparatus for manufacturing an image displaying apparatus having a display panel. A first substrate of the display panel on which a phosphor exciter is disposed and a second substrate of the display panel on which phosphors emitting light by the phosphor exciter is provided, are prepared under a vacuum atmosphere. Then, the first and the second substrates are carried in a getter processing chamber or bake processing chamber, and getter processing or bake processing is applied thereto under the vacuum atmosphere. After the processing, the first and the second substrates are carried in a seal processing chamber, where the substrates are heat sealed under the vacuum atmosphere. Thus, reduction of vacuum exhaust time and a high vacuum degree in manufacturing an image displaying apparatus is attained and efficiency of manufacturing is improved.

Disclosed is a barrier rib of a plasma display panel and forming method thereof, by which costs for fabricating the barrier rib are reduced and the fabricating method is simplified. The present invention includes forming a white paste layer on a glass substrate and forming a photosensitive black resist layer on the white paste layer, forming a photosensitive black resist pattern by patterning the photosensitive black resist layer, heating the photosensitive black resist pattern so that a wax component contained in the photosensitive black resist pattern diffuses inside the photosensitive black resist pattern, and removing a portion of the white paste layer failing to be covered with the photosensitive black resist pattern and plasticizing the photosensitive black resist pattern and the remaining photosensitive black resist pattern.
Abstract:
Manufacturing equipment and manufacturing process steps that improve upon prior art processes for the manufacturing of filament tube and arc tube light sources, their components and subassemblies, and lamps employing said light sources. A double ended, tipless filament tube or arc tube light source incorporates a drawn-down tubular body, and one piece foliated leads with spurs for process handling and for spudding into a filament with stretched-out legs. Bugled ends on the body provide a novel cutoff means, facilitate a flush-fill finishing process, and enhance mounting and support of the light sources in lamps. The foliated leads are made from a continuous length of wire in a process including foil hammering and two-bath AC electrochemical etching. Cost-reduced light source and lamp production enables affordable household consumer lamps, even when containing two series-connected halogen filament tubes. Safety benefits ensue from series connection, especially in combination with disclosed body and filament constructions.
Abstract:
Devices for electric field control in a field emission display are provided. In one implementation, a device includes a cathode substrate, a plurality of emitter lines formed on the cathode substrate, and a plurality of gate wires crossing over the plurality of emitter lines. Each gate wire has a cross section shaped to produce an electric field between adjacent gate wires that is substantially uniform and substantially flat across a portion of an emitter line in between the adjacent gate wires, the electric field causing an electron emission from the portion of the emitter line. Generally, the electric field is produced by applying a voltage potential difference between at least one gate wire and the emitter line, the electric field sufficient to cause the electron emission.
