ABSTRACT:
A plasma display panel brightness correction circuit, a brightness correction method, a video display, and a video display method are provided. One embodiment includes a continuity detector that receives video signals and detects those of the video signals having signal level values which are greater than or less than a predetermined value. A video signal corrector is also provided for applying correction factors. The correction factors are calculated according to the ratio of pixels with signal level values greater than the predetermined value to the pixels with signal level values less than the predetermined value. The video signal corrector then corrects the levels of the video signals.
