驱动等离子体显示面板的方法和相应设备
摘要：
一种利用衰减估计和补偿来驱动等离子体显示面板的方法和相应设备。在降低对比度和/或亮度时，应当改进等离子体显示面板上的图像质量。这通过以下步骤来实现：估计在等离子体显示设备的数据处理的前端(2)中出现的动态降低，并在后端(3)中补偿该降低。具体地，调整(5)视频输入数据的增益和/或偏移，并测量(10)调整的视频数据的功率电平。根据衰减信息(12)来更新(13)产生的功率电平信息。将更新的功率电平用于功率管理(9)，并且根据衰减信息来增加(14)前端(2)中降低的视频数据的电平。因此，结果，改善了视频的动态变化以及图像质量。
摘要（英）：

The invention provides a method for driving plasma display panel with attenuation estimation and compensation and a corresponding apparatus. The picture quality on a plasma display panel shall be improved when the contrast and/or the brightness are reduced. This is achieved by estimating the reduction of the dynamic occurring in the front-end (2) of the data processing of the plasma display device and by compensating it in the back-end (3). Specifically, the video input data are tuned (5) and the power level of the tuned video data is measured (10). The resulting power level information is updated (13) on the basis of an attenuation information (12). The updated power level is used for the power management (9) and the level of the video data being reduced (5) in the front-end (2) is increased (14) on the basis of the attenuation information. Thus, the dynamic of the video and, as a result, the picture quality are improved.
