Abstract: PURPOSE: To prevent a drop in display quality due to unnecessary discharge in a non-display zone without any need of increasing manufacturing manhour by arranging dummy electrodes at both sides of an address electrode group, and then connecting both ends of adjacent dummy electrodes to each other. CONSTITUTION: A plurality of dummy electrodes D are arranged in parallel to every address electrode A at both ends of an address electrode group AG for preventing unnecessary light emission outside a display zone EH. Also, both ends of the adjacent dummy electrodes D are electrically integrated with each other via a connection conductor 50, and commonly connected to an external connection terminal 62 at one side via a connection conductor 51. As a result of connecting both ends of the adjacent electrodes D, a ladder type conductor loop is formed. Thus, even if a wire breakage occurs in a part of the electrodes D, no floating state appears.

Abstract: PURPOSE:To enhance mass productivity by heightening a yield to form partition walls to regulate a clearance dimension of a discharge space in a manufacturing method of a surface discharge type plasma display panel (PDP). CONSTITUTION:In the case of manufacturing a surface discharge type plasma display panel having a structure in which a clearance dimension of a discharge space is regulated by stripe shape partition walls 29 extending in the same direction with address electrodes A crossing a display electrode for surface discharge, the first low melting point glass paste 50a is applied and dried on the forming surfaces of the partiton walls 29. Next, the second low melting point glass pastes 29a are applied on a low melting point glass paste layer 50b in a drying condition, and are baked simultaneously with the low melting point glass paste layer 50b, and the partition walls 29 are formed.

Abstract: PURPOSE:To easily execute exact drive not to excess turn-on or turn-on miss by extending the voltage margin of drive after suppressing the luminance reduction of display. CONSTITUTION:Discharging is generated at the rise edge of a discharge maintenance pulse PX, and wall charges starts being stored. With the storage of wall charges, a cell voltage is lowered and at a prescribed time point, discharging is stopped. Pulse width tx of the discharge maintenance pulse PX is set at 5-10mus, for example, and therefore, a plane discharge cell stores wall charges sufficient for surely generating discharging later. Continuously to the discharge maintenance pulse PX, a discharge maintenance pulse PY having pulse width ty (ty

Abstract: PURPOSE:To provide a multicolor segment display by alternately arraying first and second phosphors having mutually different luminescent colors in segments, and emitting light with one side or both of these phosphors, and making one color of three colors selectable, in producing a plasma display panel of a segment display method. CONSTITUTION:Seven segments SE are arranged in a 8-shaped state on a display picture plane, and the respective segments SE are demarcated into first and second luminous regions E1 and E2 aligned in one direction with partition walls 19 and 29. A discharge cell C1 is defined with electrically light-transmitted snake-like electrodes X and Xb and a first comb teeth-like electrode Y1 between seven segments SE in the region E1, and a cell C2 is demarcated similarly with the electrodes X and Xb and a second electrode Y2 in the region E2. Thus the region E1 is light-emitted with a phosphor 18G when electric discharge is caused in only the cell C1, and the region E2 is light-emitted with a phosphor 18R when electric discharge occurs in only the cell C2. A mixed color is light- emitted when the cells C1 and C2 are discharged concurrently.

Abstract: PURPOSE:To enhance display brightness and visual confirmability by a pair of electrode discharging in an electric discharge area (ES), which includes a light emission area (EH) provided with a fluorescent material and expands outside the EH. CONSTITUTION:Belt-shaped electric discharge parts 23a, 24a face one another and determins their lengths and numbers so that an electric discharge area ES may include an area EH and its outside. That is, the electric discharge part 23a, 24a, are installed so that the area ES may be about 1.5 times as large as the area EH in diameter. In order to display a PDP1, a prescribed voltage is applied across electrodes 23, 24, to induce an electric discharge in the area ES so as to produce ultravioled rays UV, which excite a fluorescent material 18 for light emission. In this case, the ultraviolet rays UV are in part diverged outside the area EH, but other ultraviolet rays are produced on the periphery of the area ES and applied to the fluorescent material 18 to compensate for the divergence loss. This increases the ultraviolet rays applied to the area EH to enhance the brightness of the area EH.
