Abstract The PDP (Plasma Display Panel) is a light‐emitting matrix display device using the luminescence of a gas discharge. It has such features as thin depth, wide view angle, freedom from geographical distortion, and high brightness. The gray scale is controlled by a subfield driving method using binary weighted pulse width modulation (LSB to MSB sequences). The subfield method essentially has a flicker problem in displaying moving images. When two similar gray values are displayed in a particular interval (field frequency), the flicker phenomenon appears. In this paper, the time‐amplitude comodulation subfield method using RBC (Redundant Binary Code) is proposed. This driving method increases the conventional two‐level gray scale {0, 1} to a three‐level gray scale {0, 1/2, 1}, combining the light‐emitting time and amplitude, and selecting the driving waveform so as not to produce flicker. Even if two similar gray values are displayed alternately in field time, the light‐emitting frequency is no longer divided into frame frequencies. The proposed driving method improves flicker compared to the conventional subfield method. © 1999 Scripta Technica, Electr Eng Jpn, 129(1): 46–52, 1999
