摘要:
An image display device having a vacuum envelope which has a light transmissible panel, a funnel and a neck, its inside held vacuum, a phosphor layer is formed on the inside surface of the light transmissible panel, an electron gun is disposed within the neck. An antistatic film which contains high-resistance fine particles having a specific resistivity of 106 to 109 Ω·cm is formed on inside wall of the neck. The image display device is free from deterioration of display characteristics caused by a change of the track of electrons emitted by the application of voltage, a spark in a tube, or a leakage current.
摘要:
A metal back-attached phosphor screen includes a light absorption layer (2) and a phosphor layer (3) on an inner surface of a face plate (1) respectively, and a metal back layer (5) formed on the phosphor layer (3). The light absorption layer (2) contains an oxygen carrier prepared by adding a reducing metal to a metal oxide. A particle size of the oxygen carrier can be set to be 1 to 10 μm. Besides, a phosphor material in which an activator such as Eu is added to a phosphor host material including oxygen such as Y2O2S, can be used as the oxygen carrier. In an image display device such as an FED, it is possible to eliminate a generation and an emission of a gas from the phosphor screen, and to improve an operation life of an electron emitting source.

A method for forming a phosphor screen comprising the step of forming a phosphor layer containing a thermoplastic resin on the inner surface of a face plate, the step of pressurizing the phosphor layer being heated to plasticate the thermoplastic resin and smooth the surface of the phosphor layer, and the step of forming a metal film on the surface-smoothed phosphor layer and heating the face plate. Thermoplastic resin having a softening temperature of 50–350° C. can be used in the phosphor layer, and 0.05–50 wt % of such a thermoplastic resin in solid content ratio is contained in the layer. Heating/pressurizing conditions preferably involve temperatures of 50–350° C. and pressures of 10–10000 N/cm2. This method enhances the film forming property of a metal back layer and prevents cracks and pinholes in the metal back layer.

摘要:
An image display device includes a face plate in which a metal back layer is formed on a phosphor screen and a rear plate having a number of electron emitting elements, and an electrically divided portion is formed at the metal back layer in a predetermined pattern. In this electrically divided portion, a covering layer including a component melting or oxidizing a metal (Al) and heat resistant fine particles such as silica fine particles respectively, and having concaves and convexes resulting from the heat resistant fine particles on a surface thereof is formed. Besides, a getter layer divided by the covering layer is formed on the metal back layer in a film shape. It is desirable that in the light absorption layer, a portion at least positioning at a lower layer of the divided portion of the metal back layer has a surface resistance of 1×105Ω/□ to 1×1012Ω/□.

This image display unit includes a face plate (6) on an inner surface of which a phosphor screen is formed, and a rear plate having a large number of electron emission elements, wherein the phosphor screen includes a light absorption layer (8), a phosphor layer (9), a metal back layer (10) having a separating portion (10a) and formed on the phosphor layer, a high-resistance covering layer (11) formed on the separating portion of the metal back layer in such a way as to be laid across the metal back layer of both sides of the separating portion, a heat-resistant fine particle layer (12) formed on the high-resistance covering layer, and a getter layer (13) formed in a film shape above the metal back layer and divided by the heat-resistant fine particle layer. In an image display unit such as an FED, a heat-resistance property is enhanced to prevent destruction or deterioration of the light emission element or the phosphor screen due to an abnormal discharge, so that display of high luminance and high quality can be realized.
摘要:
A method for forming a metal back-attached phosphor screen comprises the step of dissolving/removing or rendering highly resistant a specified area of a metal film formed on a phosphor screen by using a liquid that dissolves or oxidizes the metal film. After part of a metal film is removed or rendered highly resistant, an insulating or highly resistant inorganic material may be applied to the remaining ends thereof. Alternatively, an insulating or highly-resistant inorganic material may be added to a dissolving or oxidizing liquid to dissolve/remove or render highly resistant a metal film, and at the same time ends of the metal film are coated with the inorganic material. In this metal back-attached phosphor screen, electron emission elements and the phosphor screen are protected against destruction/deterioration by discharging.
摘要:
This dispersion liquid composition for black matrix comprises; manganese oxide having an average particle diameter in the range of 50 to 2000 nm, or solid solution of manganese oxide and ferric oxide having an average particle diameter in the range of 50 to 2000 nm and a manganese content in the range of 15 to 70% by weight; at least one kind of dispersing agent selected from a group of water-soluble acrylic resin, sodium salt, ammonium salt or potassium salt of water-soluble acrylic resin, and sodium salt, ammonium salt or potassium salt of polycarboxylic acid or ligninsulfonic acid or bisphenolsulfonic acid; and water, or a solvent mixture of water and an organic solvent compatible with water. By employing such a dispersion liquid composition for black matrix, light reflectivity of a light absorption layer of an interface with a panel is remarkably reduced. Accordingly, in a display device such as a color cathode ray tube, a display surface in which superposition of ambient light is difficult to occur is realized.
