Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a display panel capable of displaying a good image, suppressing infiltration of dust and impure gas inside a display panel during a sealing process. SOLUTION: Hot air 24 is prevented from being directly sprayed onto a joining part interface 18 between a front plate and a back plate, by avoiding the direction of jetting of the air 24 to be directly directed in the direction of the interface 18 when heating the sealing process for producing a housing in a heating furnace 21 with the air 24 circulated therein. Therefore, since the air 24 is heated while suppressing the air 24 to be entered inside a display panel 1, the dust and the gas is suppressed to be infiltrated inside the panel 1 from gaps existing in the interface 18 not sealed yet. As a result, the raise in a discharge voltage and occurrence of flicker caused by no lighting due to the dust and absorption of the gas can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device of a flat-plate image display device restraining occurrence of leakage or the like, capable of chipping an exhaust tube with high production efficiency.
SOLUTION: In the manufacturing method of the flat-plate image display device 1 equipped with the exhaust tube 5 exhausting an inner space 3, the exhaust tube 5 is sealed by softening two points 5a, 5b in different axial directions, and moving a part 5c between the two points 5a, 5b in axial direction of the exhaust tube 5. With this, a shape of a chip-off part 5d is made small, and residual stress inherent in it also gets small, so that leak generation is restrained. Further, since an interval between a vessel 2 and an exhaust head 8 is constant, a wasteful space for carrying out chipping process is eliminated, which enables improvement of the production efficiency.

Abstract: PROBLEM TO BE SOLVED: To realize a PDP to suppress noises considered to be caused by a gap generated because contact pressure between the front face substrate and the rear face substrate becomes weak in the case an image display is carried out in a low atmospheric-pressure environment such as a place of a high altitude.
SOLUTION: Because the front face substrate 2 and the rear face substrate 3 of the plasma display panel 1 are made to counter and to be sealed by pinching a first sealing member 16a and a second sealing member 16b formed outside of the first sealing member 16a by a material having a higher softening point temperature than the first sealing member 16a, at least the part outside the image display region 15 of one of the substrate is pasted in elastically deformed state. By this, while nearly flatness of the image display region 15 is secured, the contact pressure at a barrier rib 4 by the front face substrate 2 and the rear face substrate 3 is made to exist at least on one side of the front face substrate 2 and the rear face substrate 3, and a gap is hardly formed between the front face substrate 2 and the barrier rib 4.

Abstract: PROBLEM TO BE SOLVED: To realize a method of manufacturing a plasma display panel decreasing characteristic variation caused by deterioration by oxidation of a phosphor material in a thermal process in a production process. SOLUTION: Before sealing of discharge gas, excess oxygen of phosphor layers 14R, 14G, 14B generated by oxidation in the thermal process in the production process is removed, for example, gas in a discharge space is replaced by reducing gas in a state of 250°C or higher. Thereby, excess oxygen is removed by reducing action. COPYRIGHT: (C)2004,JPO
