Abstract

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 gain and/or offset of the video input data are adjusted (5) and the power level of the adjusted 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.
