    • Disclosed herein is a method and apparatus for driving a plasma display panel, which improves contrast characteristics and preventing a low discharge making a cell non-luminous at a specific gray scale. The method for driving a plasma display panel includes the steps of initializing a cell by supplying a first write voltage and an erase voltage to a scanning electrode during a reset interval of the n-th sub-field; initializing the cell by supplying the erase voltage and a second write voltage which is higher than a sustaining voltage and lower than the first write voltage to the scanning electrode during a reset interval of the (n+1)-th sub-field; selecting the cell by supplying the scanning voltage to the scanning electrode and supplying a data voltage to an address electrode during an address interval of each of the n-th and (n+1)-th sub-fields; and alternatively supplying the sustaining voltage to the scanning and sustaining electrodes during a sustaining interval of each of the n-th and (n+1 )-th sub-fields.
    • 本文公开了一种用于驱动等离子体显示面板的方法和装置,其提高对比度特性并防止在特定灰度使得不发光的电池的低放电。 用于驱动等离子体显示面板的方法包括以下步骤:在第n子场的复位间隔期间通过向扫描电极提供第一写入电压和擦除电压来初始化单元; 通过在第(n + 1)子场的复位间隔期间向扫描电极提供擦除电压和高于维持电压并低于第一写入电压的第二写入电压来初始化单元; 通过向扫描电极提供扫描电压并在第n和第(n + 1)个子场中的每一个的地址间隔期间向地址电极提供数据电压来选择单元; 以及在第n和第(n + 1)个子场中的每一个的维持间隔期间将维持电压提供给扫描和维持电极。
