    Abstract: PURPOSE:To prolong the lifetime of a plasma display panel to make full-color displaying by suppressing the deterioration of the electric discharge surface due to ion bombardment. CONSTITUTION:A plasma display panel 1 capable of presenting full-color display has three types of phosphor 28R, 28G, 28B emitting different colors R, G, B. As an electric discharge gas to emit ultraviolet rays for energizing the three types of phosphor 28R, 28G, 28R, a mixture gas chiefly containing gaseous molecules having a greater molecular weight than helium is encapsulated in the discharge cavity 30, and an optical filter 60 to absorb unnecessary visible rays emitted by the mixture gas is i-nstalled on the display panel H side of the discharge cavity 30.

    Abstract: PURPOSE:To reduce power consumption by stepwise varying the anode side power supply potential to the driving potential which is higher than the electric discharge initiation potential and to the electric discharge holding potential which is lower than the electric discharge initiation potential for every line period. CONSTITUTION:The anode side power supply potential Vy is normally kept at the discharge holding potential and is changed to the driving potential in a prescribed duration for every line period. When the anode side power supply potential Vy is at the driving potential, electrical discharges occur at the intersections of selected electrodes A1 to An and K1 to Km. Once the discharges occur, these discharges continue even though the anode side power supply potential Vy is lowered to the electrical discharge holding potential because electric charges are accumulated in the discharging space. Thus, the discharging current is limited because the anode side power supply potential Vy moves from the driving potential to the lower potential i.e., the discharge holding potential after the start of electrical discharges and the transition of the electrical discharges to arc discharges is prevented without electric current limiting resistors.

    Abstract: PURPOSE:To obtain a high-quality and high-precision display screen by partially deforming at least one of an X-electrode and a Y-electrode, deforming its plane shape, and providing a gap between shielding layers. CONSTITUTION:X-electrodes 13 and Y-electrodes 14 formed on the surface of glass boards 11, 12 are stereoscopically intersected across discharge spaces, and display cells C are formed at their intersections. Shielding layers 20 are formed, the plane shape is partially deformed on at least one of the electrodes 13, 14 on the shielding layers 20 to shield spacers 18, and preset gaps d2 are provided. Large shielding layers 20 with the same diameter as the distance d1 at the separation section of the spacers 18 or larger can be provided, and the precision for mounting the spacers 18 is mitigated. The yield in production is improved, and a high-quality and high-precision display screen can be obtained.

    Abstract: PURPOSE:To obtain a terminal processing structure having excellent airtightness by filling up a step-difference gap generated on the edge part where an electrode terminal part and a flexible cable overlapped on a joint part with a first organic covering layer having fluidity, and further, providing a second organic covering layer the small fluidity thereon. CONSTITUTION:A flexible sheet 15 is connected with a silver electrode terminal 13 via an anisotropic conductive membrane 16. After they are connected, a thermosetting anisotropic conductive membrane is hardened by a heat reaction, so that a volume change is great, and a gap is generated between the flexible sheet and a pressing terminal part. The gap of the edge part is coated with a resin 17 having the fluidity. Since the resin which is made flow into the gap of the edge part has the fluidity, it enters the gap between the flexible cable 15 and the silver electrode terminal 13, and the airtightness of the edge part is improved. Further, the edge part is coated with a resin 18 comparatively having small fluidity, and moisture-proof effect and peel strength are enhanced. In such a manner, a terminal processing structure having excellent airtightness is obtained.

    Abstract: PURPOSE:To discriminate the quality of electrode rapidly and to unify the capacity of capacitors by filling a dielectric in plural gaps between opposite crossing surfaces which have surfaces in the direction crossing to the substrate surface, and composing a specific capacity of capacitors. CONSTITUTION:At one side capacity coupling member D1, a display electrode 25 from a display 50 is picked up to a wiring surface same as a driving wave feeding bus 23-1 which is thick-membrane-printed through a throughhole M. And the electrode end 25a is thick-membrane-printed parallel and close to the driving wave feeding bus 23-1. At the electrode gap S between the electrode end 25a and the driving wave feeding bus 23-1, a micropowder with diameter less than several mu of a high dielectric substance E such as barium titanate is filled, and the capacity C is made larger. At the other side of the capacity coupling member D2 of the panel, an insulated driving wave feeding bus 24-1 is formed to hold an electrode end 26b from both sides, for example. In the D2 coupling, an integration structure of coupling unit capacity C is formed in the manner same as the coupling D1, and the accuracy of the gap is made in an accurate value.
