Abstract:
A gas discharge device constructed out of one or more plasma-shells with an organic luminescent substance(s) located in close proximity to each plasma-shell. Each plasma-shell is a hollow geometric body filled with an ionizable gas. Photons from the gas discharge inside the plasma-shell excite the luminescent substance. In one embodiment the luminescent substance is located on the external surface of the plasma-shell. In another embodiment, the luminescent substance is located inside the plasma-shell. The plasma-shell may be made of an inorganic luminescent material with organic luminescent material located on the inside or outside of the plasma-shell. The plasma-shell is of any suitable geometric shape and includes plasma-sphere, plasma-disc, and plasma-dome. A plasma-shell may be used in combination with a plasma-tube.
Abstract:
A gas discharge device comprising a multiplicity of hollow gas filled Plasma-shells located on a substrate, each Plasma-shell being wholly or partially made of a first luminescent material, an exterior portion of each Plasma-shell containing a second luminescent material. The first luminescent material comprises an inorganic material or a combination of organic and inorganic materials. The second luminescent material comprises an organic material or a combination of organic and inorganic materials. Both the first and second luminescent materials may be the same material(s). The combination of organic and inorganic materials includes mixtures, suspensions, dispersions, layers, and coatings.
Abstract:
Visual artifact reduction method for a display comprising the use of error diffusion. Other artifact reduction methods can be used with error diffusion, including gamma correction, dithering, and center of light.
Abstract:
Electrode configurations for a plasma display panel (PDP) device having one or more substrates and a multiplicity of pixels or sub-pixels that are defined by a hollow plasma-shell filled with an ionizable gas. The invention is described with reference to a plasma-disc, but other plasma-shells may be used including plasma-dome and plasma-sphere. The plasma-disc has at least two opposing flat sides such as a flat top and flat bottom or a flat rear and flat front. One or more other sides or edges may also be flat. Two or more addressing electrodes are in electrical contact with each plasma-disc, at least one electrode being in contact with a flat side of the plasma-disc.
Abstract:
Apparatus to eject on demand discrete hollow microsphere droplets that are characterized by a highly regular and predictable spherical shape, devoid of tails or other irregularities common in the prior art with a selected pure gas contained in the center. With this method and apparatus, droplets may be formed of any suitable material including glass, ceramic, plastic, or metal. A variety of gases at various pressures including complete vacuums may be contained in the hollow microsphere. Microspheres filled with ionizable gas may be used as pixels in a plasma display panel. Microspheres used as a pixel elements may be referred to as Plasma-spheres. The inside of each Plasma-sphere may contain a luminescent material such as a phosphor and/or a secondary electron emission material such as magnesium oxide or a rare earth oxide introduced during the gas filling of the microsphere.
Abstract:
A process for manufacturing a plasma display panel (PDP) device having one or more substrates and a multiplicity of pixels or sub-pixels. Each pixel or sub-pixel is defined by a hollow Plasma-disc filled with an ionizable gas. The Plasma-disc has at least two opposing flat sides such as a flat top and flat bottom. One or more other sides or edges may also be flat. Two or more addressing electrodes are in electrical contact with each Plasma-disc. A flat side of the Plasma-disc shell is in contact with a substrate and each electrode is in electrical contact with a flat side of the Plasma-disc. The PDP may include inorganic and organic luminescent materials that are excited by the gas discharge within each Plasma-disc. The luminescent material may be located on an exterior and/or interior surface of the Plasma-disc or incorporated into the shell of the Plasma-disc. Up-conversion and down-conversion materials may be used. The substrate may be rigid or flexible with a flat, curved, or irregular surface.
Abstract:
There is disclosed an article of manufacture comprising a Plasma-Disc™ for use in a plasma display panel (PDP) device having one or more substrates and a multiplicity of pixels or sub-pixels. Each pixel or sub-pixel is defined by a hollow Plasma-Disc™ filled with an ionizable gas. The Plasma-disc has at least two opposing flat sides such as a flat top and flat bottom or a flat rear and flat front. One or more other sides or edges may also be flat. Two or more electrodes are in electrical contact with each Plasma-disc. A flat base side of the Plasma-disc shell is in contact with a substrate and each electrode is in electrical contact with a flat side of the Plasma-disc. The PDP may also include inorganic and organic luminescent materials that are excited by the gas discharge within each Plasma-disc. The luminescent material may be located on an exterior and/or interior surface of the Plasma-disc or incorporated into the shell of the Plasma-disc. Up-conversion and down-conversion materials may be used. The substrate may be rigid or flexible with a flat, curved, or irregular surface.
Abstract:
Plasma-shells filled with ionizable gas are positioned on or within a rigid or flexible substrate. Each Plasma-shell is electrically connected to at least two electrical conductors such as electrodes with an electrically conductive bonding substance to form an electrical connection to each electrode. The electrically conductive bonding substance may comprise a pad connected to both the Plasma-shell and an electrode.
Abstract:
There is disclosed visual artifact reduction methods for a display comprising the use of gamma corrections, error diffusion, dithering, and/or center of light. The invention is described with reference to an AC gas discharge display (PDP), but may be practiced with other display technologies. The methods of this invention are disclosed for use with a number of PDP structures and PDP electronic addressing architectures including ADS, SAS, and ALIS. In one preferred embodiment, a center of light timing method is used to reduce artifacts between different sections of a PDP being addressed with SAS architecture.
