摘要： The object of the invention is to provide a method for driving a plasma display panel that provides an improved expression of levels of halftone as well as an improved display quality. In N sub-fields constituting a display period of one field, when a pixel data writing step for setting discharge cells to either one of non-light-emitting cells or light-emitting cells in response to pixel data and a light-emission sustaining step for allowing only the aforementioned light-emitting cells to emit light only during a light-emission period corresponding to weights assigned to the sub-fields respectively are executed, the light-emission period in the light-emission sustaining step of the respective sub-fields is changed field by field or frame by frame. According to another aspect, the invention allows for carrying out selectively a first drive pattern or a second drive pattern. The first drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, first and second light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the light-emission sustaining step during one field (one frame). The second drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, third and fourth light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the aforementioned light-emission sustaining step.

摘要： A method for driving a plasma display panel (PDP) to indicate a precise emission image corresponding to pixel data thereon. The method comprises the steps of applying first priming pulses to all of the row electrodes simultaneously to execute a simultaneous priming stage, and then applying a second pulse for reproducing charged particles in the discharge region just before applying a scan pulse for writing pixel data to the pixel cell, thereby writing the pixel data to the respective pixel cells. In other words, the application of the second priming pulse can adjust the amount of charged particles in the discharge region of the pixel cell just before applying the scan pulse to write the pixel data. Therefore, the desired amount of barrier charge corresponding to the contents of the pixel data can be achieved in the pixel cell, thereby obtaining a precise display image on the PDP panel.
摘要翻译：一种用于驱动等离子体显示面板（PDP）以指示与其上的像素数据相对应的精确发射图像的方法。该方法包括以下步骤：同时对所有行电极施加第一引发脉冲，以执行同时启动阶段，然后在施加用于将像素数据写入扫描脉冲之前，在放电区域中再次施加用于再现带电粒子的第二脉冲像素单元，从而将像素数据写入各个像素单元。换句话说，第二起动脉冲的施加可以在施加扫描脉冲以写入像素数据之前调整像素单元的放电区域中的带电粒子的量。因此，可以在像素单元中实现与像素数据的内容对应的期望量的势垒电荷，从而在PDP面板上获得精确的显示图像。

摘要： In an apparatus for processing video signals to control a display device that displays a video, a display video signal is generated for each of the colors from received video signals; a delayed display video signal is generated for each display video signal by delaying the display video signal by one field; an afterglow level of at least a first color among the colors is calculated based on the delayed display video signals; a correction signal is generated based on the afterglow level; a display video signal for the first color is selected as the display video signal of the first color when a level of the display video signal of the first color is equal to or higher than the correction signal, and the correction signal is selected when a level of the display video signal of the first color is lower than the correction signal.
