Abstract

Infrared-emission observations show that the discharge characteristics related to the MgO surface are improved in both the image sticking and boundary image sticking cells, whereas luminance observations show a deterioration in the visible-conversion characteristics related to the phosphor layer in both the image sticking and boundary image sticking cells. Consequently, the image sticking phenomenon is strongly related to the Mg species sputtered from the MgO surface of the discharge cells due to an iterant strong sustain discharge. In particular, halo-type boundary image sticking is due to the redeposition of Mg species on both the MgO and phosphor layers in the nondischarge region adjacent to the discharge region, as confirmed by Vt close curve, time-of-flight secondary ion mass spectrometry, and scanning electron microscope analyses.
