  • Patent number: 7166956
    Abstract: A metal back-attached phosphor screen comprises a metal back layer that has a high-reflectance, high-resistance layer consisting of an In-, Sn- or Bi-oxide layer. The metal back layer of the metal back-attached phosphor screen may have a laminate structure including a high-reflectance layer formed on a phosphor layer side and a high-resistance layer formed on that layer. The high-reflectance layer may be formed of Al, In, Sn or Bi. The high-resistance layer may be formed of an Al-, In-, Sn-, Bi- or Si-oxide or nitride. A high-brightness metal back-attached phosphor screen is provided that prevents the destruction or the deterioration of an electron emission element and a phosphor screen by discharging.

  • Patent number: 7157843
    Abstract: A transfer film comprising a base film (11), a parting-agent layer (12), a protective film (13), and a metal film (14), the latter three being formed on the base film (11) in order, wherein the protective film (13) contains a softening agent such as a phosphate, an aliphatic monobasic acid ester, an aliphatic dibasic acid ester, or a dihydric alcohol ester. By using such a transfer film, a metal back layer is formed. Since the transfer layer of the transfer film has a surface resistivity of as high as 102–108 ?/, the surface resistivity of the formed metal back layer is high, and discharge is suppressed.

  • Publication number: 20060138664
    Abstract: An electron source device includes a porous layer (for example, porous alumina layer) which is composed of an insulator and has many microscopic holes provided in a direction perpendicular to a main surface, and first and second conductor layers placed on both sides of the porous layer, and is characterized in that the current density I/S is 1 ?A/cm2 or higher when a direct-current voltage is applied between the second conductor layer and the fist conductor layer while using the second conductor layer as an anode. In this case, S represents the overlapping area of the first conductor layer, the second conductor layer and the porous layer. Consequently, an electron source device having a high electron emission ability and a long life even when the degree of vacuum is low can be obtained at low cost, and hence, a display having a high luminous efficiency and high reliability can be realized.

  • Patent number: 6670747
    Abstract: Phosphor layers are formed on the inner surface of a face plate. An electron source device that emits electrons to excite the phosphor layers is provided on the inner surface of a base plate. The electron source device comprises an alumina substrate that has a number of small through holes. Electron-emitting material is buried in the through holes. A reference electrode is formed on the lower surface of the alumina substrate and contacts the electron-emitting material. A gate electrode is formed on the upper surface of the substrate and insulated from the electron-emitting material. The gate electrode is configured to concentrate an electron field of the electron-emitting material by virtue of an voltage applied between the reference electrode and the gate electrode, thereby to cause the electron-emitting material to emit electrons toward the phosphor layers.
