Abstract: A plasma display panel (PDP) and a method of manufacturing the panel includes sustain electrodes having a double gap structure and a predetermined resistance value. Each of the sustain electrodes includes a main electrode for sustaining a discharge and an auxiliary electrode for starting a low-voltage discharge without decreasing efficiency. A gap between auxiliary electrodes included in different sustain electrodes, respectively, is narrower than a gap between the different sustain electrodes. Each auxiliary electrode is formed between barrier ribs or immediately above a barrier rib. A ditch is formed in a dielectric layer covering the main electrodes and the auxiliary electrodes. The ditch is formed immediately above an auxiliary electrode.

Abstract: In a plasma display panel, front and rear substrates are arranged separated a predetermined distance from each other and to face each other, forming a discharge space. A plurality of first electrodes are formed on an inner surface of the rear substrate. A first dielectric layer is formed on the inner surface of the rear substrate to cover the first electrodes. A plurality of barrier ribs are formed between the first electrodes on the inner surface of the rear substrate, sectioning the discharge space. A fluorescent substance layer is formed on a surface of the first dielectric layer and side surfaces of the barrier ribs. A first protective film formed on the surface of the first fluorescent layer. A plurality of second electrodes are formed corresponding to the first electrodes on an inner surface of the front substrate. A second dielectric layer formed on the inner surface of the front substrate to cover the second electrodes. A second fluorescent layer formed on the surface of the second dielectric layer.

Abstract: A plasma display panel using excimer gas is provided. Mixed excimer gases containing xenon (Xe) used to form excimer gas and iodine (I) as a halogen, are injected into the plasma display panel to be used as discharge gases. At least one selected from helium (He), neon (Ne), argon (Ar) and krypton (Kr) can be used as a buffering gas for the discharging gases. At least some of ultraviolet rays originate from the excimer gases and at least some of iodine is supplied from I2. The partial pressure of molecular iodine is less than or equal to a saturated vapor pressure, at operating temperature of the plasma display panel, at room temperature and at 0° C., respectively. The partial pressure of iodine inside the plasma display panel is in the range of 0.01 to 50% based on the total pressure of excimer gases.

Abstract: A method for manufacturing a cold rolled steel sheet for use in a shadow mask is disclosed, in which without adding an expensive alloy element, a short intermediate decarburization annealing is carried out, and despite this fact, a forming defect does not occur after the forthcoming stacked annealing. The method includes the steps of preparing a steel composed of, in weight %, 0.003% or less of C, 0.10-0.20% of Mn, 0.01-0.05% of Al, 0.004% or less of N, and a balance of Fe and other unavoidable impurities. A hot rolling is carried out on the steel at a temperature of above 910° C., and then, a first cold rolling is carried out to form a first cold rolled steel sheet. Then a decarburization is carried out on the first cold rolled steel sheet down to a carbon content of 0.0015% to form a decarburized steel sheet, and then a second cold rolling with a reduction ratio of more than 35% is carried out on the decarburized steel sheet.
