[0024] 1 is a schematic plan view of a burn-in process using a PDP burn-in device according to a first embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view taken along line A-A of FIG. 1 . And FIG. 3 is a schematic diagram of interconnection between each electrode of the PDP and the aging power source 16 in the PDP aging device.
[0025] First, as shown in FIG. 3 , the scan electrodes 2 ( X1 , X2 , . Commonly connected, the address electrodes 9 ( A1 , A2 , . . . , Am) are commonly connected through the short circuit device 15 . Therefore, the scan electrodes 2 and the sustain electrodes 3 are respectively connected to the burn-in power source 16 through the short-circuit device 13 and the short-circuit device 14 , while the address electrodes 9 are grounded through the short-circuit device 15 . The burn-in power supply 16 is a device for applying a predetermined voltage to the PDP to generate burn-in discharge. Wherein, a voltage pulse may also...

[0041] FIG. 5 is a partial cross-sectional schematic diagram of a burn-in device for a PDP in a second embodiment of the present invention, which is a schematic structural view for explaining the burn-in method in the second embodiment. As shown in FIG. 5 , above the panel 12 placed on the back plate 17 , a plurality of fans 18 a to 18 c fixed at predetermined positions are installed. Next, between the panel 12 and the fans 18a to 18c, vent holes 19 are provided as air blowing direction variable means for changing the blowing direction from the fans 18a to 18c. In FIG. 5, as shown by the arrows, the ventilation hole 19 swings along the direction parallel to the scan electrode 2 and the sustain electrode 3 of the panel 12 (the left-right direction in FIG. 5 ), thereby changing the air blowing direction to the panel 12. . In addition, it is configured so that the swing angle can be changed at a predetermined period (for example, within a range of 1 second to 1 minute). Thus, t...

[0046] FIG. 6 is a schematic partial sectional view of a burn-in device for a PDP in a third embodiment of the present invention, and is a schematic structural view for explaining a burn-in method in the third embodiment. In this aging device, above the panel 12 placed on the back plate 17, an air blowing device having a plurality of fans is arranged. As shown by the arrows in FIG. 6 , at least some of the fans 18 a and 18 b among the plurality of fans are configured to be movable in a direction parallel to the panel 12 . During the burn-in process, the fans 18a and 18b are moved above the panel 12 at a predetermined cycle (for example, within a range of 5 seconds to 1 minute). For example, among a plurality of fans arranged in a matrix, the fans 18a and 18b arranged in a specific column or row reciprocate in a direction parallel to the panel 12 as shown in FIG. 6 . Therefore, in the third embodiment of the present invention, at least some of the fans 18a, 18b among the plura...
