• reset discharge
• variable panel temperatures
• exo-electron emission
• ramp-slope rate

The discharge characteristics, especially the reset discharge characteristics, were examined relative to the panel temperature from -5 to 65 degrees C in an ac-plasma display panel. As the panel temperature decreased, the reset discharge became unstable, due to a decrease in the exo-electron emission from the MgO surface by the thermal activation, thereby inducing the unstable address discharge at a low panel temperature. To stabilize the reset discharge, the effects of the ramp-slope rates during the reset period on the reset discharge were examined under variable panel temperatures. Based on the experimental observation, the new temperature-adaptive reset waveform is proposed to produce a stable reset discharge irrespective of variable panel temperatures.
