The invention relates to an active matrix display device comprising a display with a plurality of display pixels, a data input for receiving a data signal and a controller for distributing said data signal over said display pixels to generate an image on said display with an overall brightness value for each display pixel during at least one frame period. The device is adapted to divide said frame period for at least one subset of said display pixels such that said display pixels of said at least one subset have at least a light output at a first non-zero brightness level during a first sub-period of said frame period and at a second non-zero brightness level during a second sub-period of said frame period, the time averaged sum of said brightness levels being substantially equal to said overall brightness level.
