20.3: Experimental Study on Temperature-dependent Characteristics of Temporal Dark Boundary Image Sticking in 42 in. AC-PDP

The temperature‐dependent characteristics of temporal image sticking, especially temporal dark boundary image sticking is investigated by observing the IR emission characteristics with respective to the cell temperature rise during the reset‐period in 42 inch AC‐PDP. The cell temperature rise in the adjacent cells is induced by that in the discharge cells (i.e., image sticking cells) due to the iterant strong sustain discharge, thus resulting in lowering the firing voltage for both the adjacent and discharge cells during the ramp‐up period. However, since the phosphor layers are deteriorated due to the strong discharge in the discharge cells, the cells adjacent to the image sticking cells show the highest luminance under the dark background image displayed only by the reset waveform.
