“Real black” plasma display panels (PDPs) having a background luminance of zero cd/m2 must be realized to obtain high picture quality. PDPs, however, must have reset discharges to initialize cell conditions, regardless of expressing any of the gray levels. The light emission from the reset discharges becomes a background luminance, degrading the picture quality having low luminance levels. A technique of substituting the role of the reset discharges is proposed for 50‐in. full‐HD PDPs. with this technique an infinite dark‐room contrast ratio is obtained. However, it has the problem of the discharge delay. A solution to this was proposed by using the frame reset or the minimum surface reset discharge and selective reset.
