    • A plasma display apparatus comprises a waveform generator (WG) coupled between first and the second electrodes (SE1, CE1) to supply, across plasma cells (PCij), a sustain voltage (VCP) with slopes comprising a main part (MA) and a minor part (MI) succeeding the main part (MA). The main part has a duration longer than a formative time 5 lag (FTL) of the plasma cells (PCij), and the minor part has a smaller amplitude than the main part (MA). The plasma cells (pCij) are ignited and sustained by the minor part (MI). The main part (MA) has less steep slopes than the prior-art waveform. Consequently, the EMI produced by the main part (MA) will be at a lower frequency. The minor part (MI) has an amplitude which is relatively low and thus does not add considerably to the EMI, even 10 when its slopes are relatively steep. As the plasma is neither ignited nor sustained by the main part (MA), the main part (MA) further has a lower amplitude than the slope of the prior art and thus produces less EMI.
    • 等离子体显示装置包括耦合在第一和第二电极(SE1,CE1)之间的波形发生器(WG),以便通过等离子体单元(PCij)提供具有斜率的维持电压(VCP) 主要部分(MA)和次要部分(MI)在主要部分(MA)之后。 主要部分的持续时间比浆细胞(PCij)的形成时间5延迟(FTL)长,并且次要部分具有比主要部分(MA)更小的幅度。 血浆细胞(pCij)被小部分(MI)点燃并维持。 主要部分(MA)具有比现有技术波形更陡峭的斜坡。 因此,主要部分(MA)产生的EMI将处于较低的频率。 次要部分(MI)的幅度相对较低,因此不会显着增加EMI,即使在斜率相对陡峭时也是如此。 由于等离子体既不被主要部分(MA)点燃也不被维持,主要部分(MA)还具有比现有技术的斜率更低的幅度,因此产生更少的EMI。
