摘要： A display device for displaying pictures by sequentially performing an address period and a sustain period. The panel pixels are arranged into groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short time after an address operation is performed on the pixels, so that a stable sustain discharge occurs even though narrow scan pulses and address pulses may be applied during the address operation. Also, the time required to address all pixels is reduced.

摘要： A display device for displaying pictures by sequentially performing an address period and a sustain period, such as, a plasma display panel (PDP), is provided. The pixels of a panel are arranged into a plurality of groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a certain group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of each of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short period of time after an address operation is performed on each of the pixels, so that a stable sustain discharge occurs even though narrow scan pulses and address pulses may be applied during the address operation. Also, the time required to address all pixels is reduced.

摘要： A method for driving a display panel to produce an efficient sustain discharge is provided. In one embodiment, the display panel includes a plurality of scanning electrodes that are driven by a sustain discharge signal. A corresponding plurality of common electrode groups is driven individually by different sustain discharge signals. Sustain discharge is performed by alternately applying high level sustain pulses to each the plurality of scanning electrodes and each the plurality of common electrode groups. Sustain pulses with a high level are applied sequentially to each the plurality of common electrode groups in time intervals between the sustain pulses with the high level applied to the plurality of scanning electrodes. Therefore, it is possible to maintain a duty rate of a sustain discharge signal near 50% while reducing a peak value of currents generated upon sustain discharge driving, thereby achieving stable sustain discharge.

摘要翻译： 提供了一种用于驱动显示面板以产生有效维持放电的方法。 在一个实施例中，显示面板包括由维持放电信号驱动的多个扫描电极。 相应的多个公共电极组由不同的维持放电信号分别驱动。 通过对多个扫描电极和多个公共电极组中的每一个交替施加高电平维持脉冲来进行维持放电。 在施加到多个扫描电极的高电平的维持脉冲之间的时间间隔中，以多个公共电极组的顺序地施加具有高电平的延迟脉冲。 因此，可以将维持放电信号的占空比维持在50％附近，同时降低在维持放电驱动时产生的电流的峰值，从而实现稳定的维持放电。
