Three-dimensional emission characteristics of a weak discharge in reset period of plasma display panels

Three-dimensional IR emission characteristics of a weak discharge in the reset period were investigated with the specially fabricated 3-D test panel which has a glass prism instead of one flank of a closed wall in ac PDP. Based on the 3-D images of the IR emissions measured in the reset period, the IR emissions from the cathode electrodes were not observed all through the rising and falling ramp reset period. During the falling ramp reset period, the emissions from the X and A_y electrodes, which work as anodes, were seen. Moreover, it was observed that the address obviously discharge occurs between the Y and a part of address (A_x) electrode. These results were experimentally confirmed with the 6-in 3-D plasma display panel.
