Abstract (en)

[origin: WO2004023452A1] A control unit and a method for reducing interference patterns when an image is displayed on a screen at a pixel frequency (ppll clk). The image is described by pixel data and the screen is provided with said image via a control unit. While the pixel data is generated, the clock signal used during the generation of said pixel data is varied or the pixel frequency is modified.
