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.

Abstract: A method and a structure for a converging-type electron-emission source of a field-emission display are disclosed. A substrate is provided, and a silver paste is used to form a first electrode layer on the substrate by the process such as thick-film photolithography or screen-printing. A carbon nanotube is formed on the first electrode layer by thick-film photolithography or screen-printing, and a second electrode is formed on the carbon nanotube. A third electrode layer is formed on the first electrode layer around the second electrode layer by thick-film photolithography or screen-printing. The third electrode layer is higher than the second electrode layer, such that a converging exit is formed around the second electrode layer. A sintering step is performed. When the electron beam is generated, the electron beam is concentrated at the center of the converging exit to impinge a phosphor layer of an anode without causing gamut.

Abstract: A method and a structure for a converging-type electron-emission source of a field-emission display are disclosed. A substrate is provided, and a silver paste is used to form a first electrode layer on the substrate by the process such as thick-film photolithography screen-printing. At least one pit is formed in the first electrode layer by etching, for example. A passivation layer is formed on the first electrode layer around the pit. A second electrode layer is formed in the recess by photolithography or electrophoresis, for example. Preferably, the second electrode layer is formed with a top surface lower than a periphery of the pit, such that a converging opening of the second electrode layer is formed over the second electrode layer. The passivation layer is then removed, followed by a step of sintering process.

Abstract: A developable phosphor coating mixture solution and its manufacturing technique on anodic phosphor layers are described. The anodic phosphor layer of the field emission display is achieved through a silkscreen-printing method copulated with exposure procedure. The process is a simple silkscreen-printing method on an anodic glass substrate. Material features are combined with the manufacturing process to increase the adhesion ability of the phosphor powder on the anodic laminate. The exposure procedure develops high-resolution photography. The simple process and low cost coating can be used in manufacturing glass substrates.

Abstract: A carbon nanotube suspension uses water as the basic solvent added with dispersant, stabilizer, coalescing aid, adhesion promoter, and a carbon nanotube. The basic solvent and the above solutes form a low viscosity solvent with carbon nanotube suspending therein.

That is, the carbon nanotube can be coated on a surface for forming the carbon nanotube electron-emission layer.

Abstract: A field mission display has a filter layer, using three primary colors, green, red and blue, filters or screen printing or spray to form three primary colors on the light source output surface of the anode electrode layer thereof. When a voltage is applied from a driving circuit to the gate conductive layer and the cathode electrode layer, an electron beam is generated from the cathode electrode layer. The electron beam impinges the white phosphor powder of the anode electrode to create a white light source. The white light is then processed three primary color filters or structures to create a color image. Such device simplifies the structure of the anode electrode layer and the driving circuit. In addition, the luminescent efficiency of various colors of phosphor powder is no longer a factor affects the luminescent characteristics display.
