Abstract

PURPOSE:To obtain a bright high-quality picture which has a slight flicker, by generating a write field and an erase field afternately on a basis of vertical synchronizing signals and increasing the ratio of the light emission period to the non- light emission period. CONSTITUTION:X electrode driving circuit 12 drives electrode groups X1, X2...Xm of panel 18 by display signal pulses, and Y electrode driving circuit 17 drives electrode groups Y1, Y2...Yn by holding pulses, erase pulses and line selection pulses. In this case, for example, erase pulses are given to odd-numbered scanning electrode groups in the next odd field erase period EFO 3x1/60 seconds after odd field write period WFO, and picture elements given to the scanning electrode emit light for 1/60 seconds and extinguish light for 1/60 seconds and repeat these operations at a period of 1/15 seconds. That is, a write field and an erase field are generated alternately on a basis of vertical synchronizing signals, and the ratio of the light emission period to the non-light emission period is increased, so that a bright high- quality picture which has a slight flicker can be obtained.
