Abstract:
A method of driving a plasma display panel having a plurality of row electrodes and a plurality of column electrodes crossing said row electrodes, the method comprising:displaying a digital picture signal in a grey level with a plurality of bits from the most significant bit to the least significant bit, each adjacent, less significant bit corresponding to less displaying time than an adjacent, more significant bit;dividing said plurality of bits into at least two groups; andscanning one group of said at least two groups of bits using one group of scan electrodes and scanning another group of bits using another group of scan electrodes, wherein said plurality of bits include even bits I.sub.8, I.sub.6, I.sub.4, I.sub.2 and odd bits I.sub.7, I.sub.5, I.sub.3 and I.sub.1, wherein time intervals between subfields of the bits from the most significant bit I.sub.8 to the least significant bit I.sub.1 are determined as 0, 0, T.sub.NS1, T.sub.NS2, T.sub.NS3, T.sub.NS4, T.sub.NS5 and T.sub.NS6, and wherein T.sub.NS1 =T.sub.A /4; T.sub.NS2 =3T.sub.A /8; T.sub.NS3 =7T.sub.A /16; T.sub.NS4 =15T.sub.A /32; T.sub.NS5 =31T.sub.A /64; T.sub.NS6 =63T.sub.A /128; and T.sub.A is the time required for scanning all of said plurality of row electrodes.
