Analysis on reset discharge characteristic in AC-PDP with sustain gap of 200 μm

The reset discharge characteristic is investigated in a sustain gap of 200 μm. As the sustain gap is wider, the stable weak discharge region using an MgO cathode condition is decreased, whereas the unstable weak discharge region using a phosphor cathode condition is increased. To reduce the unstable reset discharge in a sustain gap of 200 μm, the bias voltage (V_add-bias) needs to be applied additionally to the address electrode during the ramp-up period and the X-bias voltage (Vcom-bias) needs to be controlled properly to the common (X) electrode during the ramp-down period. The reset discharge in a sustain gap of 200 μm are examined in detail relative to the two parameters such as V_add-bias and V_com.bias.
