luminance attenuator apparatus and method in the PDP

摘要

The present invention is a luminance attenuation apparatus and method capable of preventing deterioration in image quality and increase in power consumption resulting in a localized area in the plasma display panel.; Luminance attenuation device according to the invention, for detecting whether the movement of the input data, a motion detector; When detecting that the movement to the data inputted by the motion detection unit is not present, the duration check unit for checking the duration of the movement state does not exist; When the movement state does not exist, the last for a predetermined time, the unit for generating a damping constant that corresponds to the luminance level of input data occurs attenuation constant; In accordance with the damping constant generated from the damping constant generating unit includes a level attenuation for attenuating the brightness level of the input data.; Therefore, it is possible to prevent a localized area of ​​the luminance degradation and the consequent increase in the power consumption does not affect the average brightness level of the frame.
