Abstract:
An electromagnetic-wave shielding material, such as a conductive mesh member 3, is bonded to a front surface of a PDP body 20 by transparent adhesives 4B, 4C and a transparent base plate 2 is bonded to a surface of the electromagnetic-wave shielding material by transparent adhesives 4A so that they are integrated together. In this way, electromagnetic-wave shielding efficiency is imparted to a display panel itself, thereby lightening its weight, making its wall thinner, reducing the number of parts, and thus improving the productivity and reducing the cost.
Abstract:
A flat radiator (4), suitable for a dielectrically impeded discharge and with a discharge vessel (5) made from an electrically non-conducting material has strip-like electrodes (6, 7) arranged on the wall of the discharge vessel (5), cathodes (6) and anodes (7a) being arranged alternately next to one another, and at least the anodes being separated from the interior of the discharge vessel (5) by a dielectric material (10). In each case one additional anode (7b) is arranged between neighbouring cathodes (6), that is to say in each case one anode pair (7a, 7b) is arranged between the neighbouring cathodes (6). The result is a uniform discharge structure accompanied by optimum utilization of the discharge vessel. FIG. 3b
Abstract:
A partition of a plasma display device is fabricated by forming a dielectric layer on the surface of a rear substrate having an address electrode; forming a conductive layer and a photoconductive layer in order on the surface of said dielectric layer; charging the surface of said photoconductive layer; exposing aid photoconductive layer covered with a mask of a predetermined pattern to ultraviolet rays so that an electrostatic latent image can be formed on said photoconductive layer; developing the electrostatic latent image by allowing said photoconductive layer, on which the electrostatic latent image is formed, to be in contact with a charged liquid toner layer so that liquid toner can stick to the electrostatic latent image; drying the toner stuck to the electrostatic latent image and absorbing the toner remaining an area other than the electrostatic latent image; repeating three times the steps from said step of charging the surface of said photoconductive layer through to said step of drying and absorbing the toner; and burning the rear substrate where partitions are formed.
Abstract:
An electrode structure of a PDP (plasma display panel) and its manufacturing method, where the production cost is curtailed with the extension of life by forming a protection layer of excellent properties and low cost on an insulating substrate during the manufacture of the panel. The structure comprises two substrates coupled in parallel with each other by frit glass. One of the two substrates has sustain electrodes. One or more dielectric layers are formed over the sustain electrodes, and an interfacial reaction preventive layer and a protection layer are formed over the dielectric layers. The other substrate has address electrodes arranged thereon. A lower dielectric layer is formed over the address electrodes. Barriers coated with phosphor are formed between the upper and lower substrates. The protection layer may be deposited in a multilayered form by a spin coating method.

Abstract:
A plasma display device has a first plate and a second plate which face each other with a discharge space therebetween, and a sealing member which is provided between the first and second plates to seal the discharge space at edges of the first and second plates. A plurality of electrodes are formed on the inner major surface of the first or second plate. An electrode diffusion preventive layer is formed in each area where the plurality of electrodes cross over the sealing member, so as to avoid direct contact between the plurality of electrodes and the sealing member. As a result, problems such as breaking of the electrodes can be avoided. This construction is especially effective when the electrodes contain Ag.
