Abstract:
A method of relocating spacers using inductive attraction. A chuck employs the inductive attraction to lift field emission display (FED) spacers, wherein the spacers are provided with susceptibility to the employed attraction. The spacers are lifted by the chuck and relocated to a desired position. The inductive process uses a non-contact force, including electrostatic and magnetic forces.
Abstract:
The present invention describes a package method for a field emission display. First, a photolithography or a laser process is used to fix the location of the side glasses on the anode and cathode plates. Next, these side glasses are respectively bonded to the anode and cathode plates. Then, an alignment process is performed to generate a gap between the side glasses and the gap is filled with glass frits. Finally, the whole structure undergoes a thermal cycle to make the side glasses adhere to each other so that the anode plate and the cathode plate may be sealed.
Abstract:
The present invention relates to a supporting spacer mounting structure and method for a field emission display. By using a supporting spacer structure being cross-shaped or rectangle-shaped and being made of glass, ceramics or metal, and employing the vacuum absorption of a clipping arm with special design and the real time monitoring of a monitoring lens, the position-aligning is preliminarily performed on a supporting spacer, and then the supporting spacer is positioned on a required location so as to provide the supporting force needed by a display.
Abstract:
This invention is an improved processing method and structure for the packaging technique of a large size field emission display. A large size field emission display includes an indium-tin oxides (ITO) conducting glass substrate, which is covered by the first screen mask and the second screen mask defined to a BM layer area, a multi-phosphor layer area and a hollow area. Each area was coated to form an Al layer, which was formed an AlOx layer through a phosphor sintering process. The spacer was fixed in a hollow area of an AlOx layer through an anodic assembling technique. The next plate was fixed on the spacer to accomplish an aligner process.
Abstract:
A method of bonding spacers to an anode plate of a field emission display. An anode plate having separate phosphor regions is provided, wherein a black matrix material is provided to separate the phosphor regions from one another. A magnetic layer is formed on the black matrix material. A thin metal film is formed on the anode plate and the magnetic layer. Spacers are disposed on the metal film above the black matrix material. An electromagnetic induction procedure is performed to heat the magnetic layer and thus serves as a heating source to produce heat, wherein the heat goes through the metal film to heat the spacers. A direct current (D.C.) electric field procedure is performed to bond the spacers to the metal film above the black matrix material.
