Abstract:
Provided are a novel blue BAM phosphor and a preparation method thereof. In the blue-emitting phosphor, a magnetoplumbite phase is epitaxially formed as a protection film on the β-phase of a blue BAM phosphor. The blue-emitting phosphor has high luminosity and broad color gamut, is invulnerable to mechanical damage, and can create uniform images, and thus, is very useful in fabrication of a high quality plasma display panel.
Abstract:
A sealing structure and a plasma display panel employing the same. A front plate, a rear plate, and a sealing layer are all provided. Sealing strength and reliability of the sealing structure are improved by the intended position and geometric shape of the sealing layer located between the front plate and the rear plate, thereby raising plasma display panel yield.

Abstract:
A display device comprises a substrate and a laminate structure formed on the substrate and comprising a plurality of layers including a display region. The laminate structure has a recessed/projected portions at least one of an outermost surface of display side and an interface between the layers. The projected portions of the recessed/projected portions have a mean circle-equivalent diameter ranging from 50 nm to 250 nm with the standard deviation of circle-equivalent diameter of the projected portions being within the range of 10 to 50% of the mean circle-equivalent diameter, and a mean height ranging from 100 nm to 500 nm with the standard deviation of height being within the range of 10 to 50% of the mean height. The projected portions have a circularity coefficient ranging from 0.6 to 1, and an area ratio ranging from 20 to 75%.
Abstract:
An electromagnetic wave shielding filter for a plasma display panel, for example, and a method of manufacturing such a filter includes preparing a substrate such as a metal plate that can act as a seed layer for electrolytic plating; forming a mesh plating layer on an upper surface of the metal plate; adhering an adhesive film to an upper surface of the plating layer; and separating the adhesive film from the metal plate so that the plating layer is adhered to a lower surface of the adhesive film. An electromagnetic wave shielding layer, which is installed to shield electromagnetic waves generated during the driving of a plasma display panel, for example, is formed in a mesh pattern, and the mesh pattern is created on a metal plate by electrolytic plating.
Abstract:
A display panel structure, which includes plasma display panel and filter, wherein the plasma display panel further has front glass and rear glass. Through this front glass, the plasma display panel displays images to the outside. The rear glass is corresponding to the front glass and is inter-spaced with the front glass. There is plasma enclosed between the rear glass and the front glass. The filter is directly formed upon the front glass, so the filter may be enforced and supported by the front glass and the original glass layer within the filter may be removed.
Abstract:
The disclosure teaches using at least two orthogonal arrays of complicated shaped glass rods or very large fibers-like structures (from here in referred to as fibers) with wire electrodes to fabricate plasma displays with plasma cells larger than 0.05 mm3 in volume. (The volume of a plasma cell is defined by the width of the plasma channel times the height of the plasma channel times the pitch of the pair of sustain electrodes.) To increase the size of the bottom fiber and keep the addressing voltage constant or to reduce the addressing voltage, the address electrode is moved from the bottom of the channel up into the barrier rib. Moving the address electrode up into the barrier rib will reduce the distance, d, between the address electrode and the sustain electrodes, thus increasing the electric field of the addressing pulse. To maintain a more uniform addressing field and build redundancy into the display an additional address electrode can be included in the barrier rib wall on the other side of the plasma channel.
Abstract:
A plasma display panel includes a fluorescent layer having a red phosphor pattern, a green phosphor pattern, and a blue phosphor pattern, wherein the red phosphor pattern contains Y(V,P)O4:Eu and (Y,Gd)BO3:Eu. The plasma display panel emits red light having an appropriate luminance, improved color purity, and improved afterglow properties.
