Reduction of the temporal bright?image sticking in AC?PDP modules using the vacuum sealing method

Abstract

This paper investigates the effects of the existing sealing methods, such as the conventional atmospheric‐pressure sealing method and vacuum sealing, on temporal bright‐image sticking. To produce a residual image caused by temporal bright‐image sticking, the entire region of a 42‐in panel with an Xe‐(11%)‐He(35%) gas mixture was abruptly changed to a full‐white background image after displaying a square‐type image at peak luminance for about 60s. From the monitoring of the difference in the display luminance, infrared emission, color temperature, and disappearing time between the cells with and without temporal bright‐image sticking, it was observed that the vacuum sealing method contributes to the reduction of temporal bright‐image sticking.
