Abstract:
A PDP driving method, with a plurality of sustaining electrodes (X1ËœXm), a plurality of scanning electrodes (Y1ËœYn), configured in an alternate sequence as X1-Y1-X2-Y2-X3-Y3 . . . Xm-Yn on said PDP, and a plurality of address electrodes cross over said sustaining electrodes and scanning electrodes, wherein:according to the sequence, said sustaining electrodes (X1ËœXm) are divided into odd sustaining electrodes (Xodd) and even sustaining electrodes (Xeven), and said scanning electrodes (Y1ËœYn) are divided into odd scanning electrodes (Yodd) and even scanning electrodes (Yeven); dark areas (Gj) are located between said odd scanning electrodes (Yodd) and said odd sustaining electrodes (Xodd), and said even scanning electrodes (Yeven) and said even sustaining electrodes (Xeven), in which no display data is written, and display areas (Dj), written with display data, are located between said odd scanning electrodes (Yodd) and said even sustaining electrodes (Xeven), and between said even scanning electrodes (Yeven) and said odd sustaining electrodes (Xodd), wherein, n, m and j are integers, and 1&lE;j&lE;n and m; when a voltage difference between adjacent said sustaining electrodes (X1ËœXm) and said scanning electrodes (Y1ËœYn) is greater than a firing voltage, said adjacent sustaining electrodes (X1ËœXm) and scanning electrodes (Y1ËœYn) start a discharge operation in said dark areas (Gj) and display areas (Dj), said driving method comprising the following steps(a) at a first timing point in a reset period, a first driving voltage pulse is sent to said odd sustaining electrodes (Xodd) and said even scanning electrodes (Yeven), and a second driving voltage pulse is sent to said odd scanning electrodes (Yodd) and said even sustaining electrodes (Xeven), wherein a first voltage difference, generated by said first and second driving voltage pulses, between every said adjacent pair of said odd scanning electrodes (Yodd) and odd sustaining electrodes (Xodd), and every said adjacent pair of said even scanning electrodes (Yeven) and even sustaining electrodes (Xeven) has to be above said firing voltage so as to make said discharge operation occur in said dark areas (Gj); and (b) at said first timing point in the reset period, a second voltage difference, generated by said first and second driving voltage pulses, between every said adjacent pair of odd scanning electrodes (Yodd) and even sustaining electrodes (Xeven) has to be below said firing voltage to make said discharge operation not occur in said display areas (Dj), wherein the voltage of one of said first driving voltage pulse and said second driving voltage pulse is zero.
