Abstract:
A method of manufacturing a luminous sheet according to the present invention enables a planar display unit radiating fluorescence upon irradiation of ultraviolet rays to be easily offered. A ability of radiating fluorescence is also increased. To this end, an ultraviolet-excited luminous material is applied and dried over a film-like base sheet 10 to form a light emitting layer 20, and a resin solution is applied and dried over an upper surface of the light-emitting layer to form a back layer 40. After thus forming the light-emitting layer 20 and the back layer 40 into a one-piece body, the base sheet 10 is peeled off from the light-emitting layer 20. The specific gravity of the fluorescent material is selected to be three times or more the specific gravity of the resin solution used for forming the ultraviolet-excited luminous material.

This disclosure relates to a color PDP comprising a plurality of striped color filters formed in parallel on the inner surface of a front plate, a plurality of dielectric layers formed on the color filters and having a plurality of light-passing holes formed at predetermined intervals on those portions corresponding to respective color filters, a white fluorescent layer formed on the dielectric layer, and a plurality of anodes formed on the white fluorescent layer corresponding to the color filters and each having light-passing openings formed on the portion corresponding to respective light-passing holes of the dielectric layer, thereby preventing optical crosstalk between adjacent cathodes in the direction of a scanning line and obtaining uniform luminance.
Abstract:
A driving circuit for a gas discharge panel comprises display cells between first and second electrodes and control cells between the first electrodes and third electrodes which are in one-to-one correspondence with the first electrodes. The circuit comprises a small number of diodes connected to each third electrode and transistors, fewer in number than the third electrodes, divided into a small number of subgroups. The diodes connected to each third electrode are connected to one of the transistors of the respective subgroups. The transistors connected to only one of the third electrodes are rendered nonconductive at any given time.

Abstract:
A plasma display device disclosed herein is capable of enhancing the contrast of external light, facilitating application of phosphor paste on the bottom of each space surrounded by lattice-like barrier ribs, and reducing a variation in the amount of the phosphor paste applied as much as possible. The lattice-like barrier ribs include lateral ribs extending along a first direction while being nearly in parallel to each other, and vertical ribs extending along a second direction different from the first direction while being nearly in parallel to each other. Each of the lateral ribs is composed of two or more rows of rib elements. Notches for communicating spaces surrounded by the vertical ribs and the lateral ribs to each other in the first direction and/or the second direction are formed at least in portions of the vertical ribs and/or the lateral ribs.

Abstract:
The present invention relates to plasma display panel and manufacturing method thereof to simplify the manufacturing steps and reduce cost of production. In the present invention, a black layer formed between a transparent electrode and a bus electrode is formed together with a black matrix at the same time. In this case, the black layer is formed together with the black matrix in one. Cheap nonconductive oxide is used as a black powder of a black layer. Specifically, in case the black layer and the black matrix are formed in one, the bus electrode is shifted to a non-discharge area to improve the brightness of the plasma display panel.
