초록

The degradation characteristics of R, G, B phosphor layers in AC-PDP, which is due to the discharge of plasma, are still unknown. For the successful commercialization of AC-PDP, the degradation of phosphor layers, caused by the plasma discharge must be investigated and improved. In this paper, the degradation properties of phosphor layers in AC-$PDP_S$ are investigated. It takes long time to investigate the degradation in real condition, so that the device for accelerating the degradation is devised. To prove the performance of the device, the visible emission characteristics of phosphor layers and discharge with the environmental temperature are examined. As a result, it is shown that the phosphor layers are easily degraded when the discharge is sustained under high environmental temperature condition. After accelerating the degradation of blue Phosphor layer((Ba,Eu)Mg$AI_10$$O_17$) for 48 hours, its luminance decreases about 38 % and the corresponding color purity deteriorates severely.
