Abstract— As the Xe content of PDPs is increased, the space‐charge priming becomes more effective. Also, the diffusion/drift of the space charges and accumulation of the wall charges becomes faster. These facts indicate that the use of an erase addressing is preferable for high‐Xe‐content PDPs. A 30%‐Xe green test panel was driven with contiguous subfields using erase addressing and a grouped Address‐While‐Display scheme. Crosstalk was suppressed by driving the odd and even sustain electrodes separately. The fast addressing speed of 0.283 μsec allowed for 121 subfields and 122 gray levels, with a resultant luminance of 4200 cd/m 2 and a dark‐room contrast of 310:1. The scan and data pulse voltages were as low as 90 and 75 V, respectively. All the subfields had an identical length of 136 μsec, but the number of sustain pulses in these subfields could be varied between 2 and 20. By selecting an adequate number of sustain pulses in the subfields, arbitrary gamma characteristics could be realized. A gray‐scale expression having a constant difference between the consecutive “perceived” luminance levels was verified throughout all the luminance levels.
