Abstract
The present invention relates to a method for displaying an image in an active matrix display device and more particularly in an active matrix OLED (Organic Light Emitting Display) display. The purpose of this invention is to increase the video dynamic range of each color component. The voltages applied to the OLED cells are based on reference voltages or currents. According to the invention, a different set of reference voltages is used for each color component. To this end, the video frame is divided into at least three sub-frames and at least one color component of the picture is addressed during each subframe with a set of reference voltages adapted to said color component.
