A method for manufacturing a flat fluorescent lamp is provided. The method involves: preparing a transparent front plate; preparing a transparent back plate facing the front plate, the back plate having a plurality of discharging electrodes thereon and a dielectric layer covering the discharging electrodes; forming a plurality of spacers between the front plate and the back plate to keep a separation gap therebetween; and forming a fluorescent layer by spraying phosphor slurry on one surface of at least one of the front plate and the back plate.

摘要:
A method of coating the bulb wall of a low-pressure mercury vapour discharge lamp with a luminescent layer, whereby a monomer and an initiator are added to a suspension comprising at least a luminescent material and a binder before a layer of this suspension is provided, which monomer is polymerized after drying of the suspension layer in order to fix the luminescent material and the binder.

An apparatus for supporting a cathode-ray tube panel (20) includes a pair of holders (22) movable to come close to each other and to be separated from each other. Each holder (22) includes elastic rollers (34). The panel (20) is located between the rollers (34) of the pair of holders (22). After the panel (20) is located between the rollers (34) of the holders (22), the holders (22) are moved to a surfaces of the panel (20). The rollers (34) of the holders (22) are brought into contact with the surfaces of the panel (20). The holders (22) are interlocked with an actuator (40). The actuator (40) is interlocked with a lock plate (44) through a ratchet mechanism (46). The holders (22) can freely come close to each other by the ratchet mechanism (46) although the lock plate (44) is not pivoted. The holders (22) can be brought into contact with panels (20) having different sizes. In a contact state, the acuta- tor (40) locked with the lock plate (44) through the ratchet mechanism (46) is pivoted by a predetermined angle so as to cause the holders (22) to come closer to each other. When the holders (22) are thus moved, they are locked. Therefore, the rollers (34) of the holders (22) are kept in tight contact with the surfaces of the panel (20) and are elastically deformed. The panel (20) can be held at a constant contact pressure corresponding to the pivot angle.

A slurry composition for forming a layer is provided. The slurry composition includes 100 parts by weight of a metal oxide selected from the group consisting of MgO, CaO, SrO, BaO, ZrO 3 , and a combination thereof; 1-200 parts by weight of a binding agent per 100 parts by weight of the metal oxide, the binding agent being selected from the group consisting of calcium phosphate (CaP), a calcium-barium-boron-based (CBB-based) oxide, a triple carbonate ((Ca, Ba, Sr)CO 3 ), and a combination thereof; 1-10 parts by weight of a binder per 100 parts by weight of the metal oxide, the binder being selected from the group consisting of nitro cellulose, ethyl cellulose, methyl methacrylate, and a combination thereof; and 50-500 parts by weight of a solvent per 100 parts by weight of the metal oxide.
摘要:
A plasma display device, characterized in that a blue phosphor in the phosphor layer thereof comprises a phosphor having a crystal structure of MeMgSi2O6:Eu or Me3MgSi2O8:Eu, wherein Me represents one or more of Ca, Sr and Ba, which is prepared by the use of a precursor synthesized by any of an aqueous solution synthesis, a spray synthesis and a hydrothermal synthesis, and the blue phosphor has an average particle diameter of 0.1 to 3.0 mum. The plasma display device exhibits high luminance and is reduced in the deterioration of luminance during the driving of the panel thereof.
