A phosphor screen is formed by using a manganese-activated zinc silicate phosphor having an average particle size of 0.5 to 2.0 μm, and a zinc-to-silicon atomic ratio (Zn/Si) of 1.65 to 1.85.
摘要:
An image display unit having a structure in which a heat-resisting fine particle layer is formed on a metal back layer disposed on a phosphor layer, and a getter layer is deposited/formed on the heat-resisting fine particle layer by vapor-depositing. The fine particle layer is desirably formed in a specified pattern, and a filmy getter layer is formed in a pattern complementary to the former pattern. The average particle size of heat-resisting fine particles which may use SiO2, TiO2, Al2O3, Fe2O3 is 5 nm to 30 μm. Since abnormal discharging is restricted, the destruction and deterioration of an electron emitting element and a phosphor screen are prevented to provide a high-brightness, high-grade display.

摘要:
An oxide composite particle of the present invention is composed of at least one fine gold particle contained in a matrix of an oxide particle or at least one fine gold particle supported fixedly on the surface of an oxide particle, and absorbs a visible light having a specific wavelength. A phosphor of the invention has a thin film which is composed of such oxide composite particles on the surface of a phosphor particle of red or the like. The phosphor can be obtained by mixing phosphor particles into a dispersion of gold colloid/oxide composite particles, agitating the resultant mixture, and taking out the precipitated phosphor particles, followed by drying. Further, in a color filter of the invention, a filter layer of at least one color formed on an inner surface of a panel is a thin film composed of the above-described oxide composite particles. This provides a phosphor or color filter which is excellent in optical characteristics, heat resistance and non-toxicity and never interferes with the irradiation of a photoresist with ultraviolet rays, and realizes a color display which exhibits good luminous chromaticity and is excellent in brightness and contrast.

Disclosed is a data entry keyboard which has a multitude of depressible keys which are selectively depressed for the entry of predetermined data. In the keyboard, an insulating member is sandwiched between a first substrate having stationary electrodes and a flexible second substrate having movable electrodes. The stationary and movable electrodes face one another through apertures formed in the insulating member. Upper and lower marginal surface portions of the insulating member, including the respective peripheral edges of the apertures, are kept parallel to the first and second substrates corresponding thereto by a plurality of protuberances on the substrates so that voids with a predetermined width are left between the marginal surface portions and the individual substrates. The movable electrodes of the second substrate are electrically fixed, in the form of a cantilever each, to the extreme end portions of branch conductor strips which diverge from a main conductor strip at right angles thereto. When one of the keys is depressed, the second substrate is deformed to narrow the corresponding void, thus bringing the corresponding movable and stationary electrodes into contact with each other.
