Abstract
To prevent burn-in of images, notably with pixels (14) driven via non-linear two-pole switching elements (8), a display device is controlled in such a way that the charge transport through the two-pole element is substantially independent of the grey level. Capacitance variations due to pixel voltage variations are compensated by adapting the voltage change across the pixel (14) via extra reset signals and/or compensation signals.
