ABSTRACT:
A drive of a display device based on polymer LEDs, for example pixels arranged in the form of a matrix, in which the lifetime is increased by writing the information from an interlaced signal each time into two successive rows. The driving may be based on voltage control at which voltages across the pixels define the picture to be displayed, but may alternatively be based on current control.
