Abstract:
1. A display system comprising a plurality of display devices, each display device having a non-pixel addressable light output part and a pixel addressable light output part in an optical path, the non-pixel addressable light output part and the pixel addressable light output part being arranged to both have a temporal modulation, so that a perceivable optical output of the display device is a combination of the outputs of the temporal modulation of the pixel addressable light output part and the temporal modulation of the non-pixel addressable light output part, and at least two of the display devices being arranged for displaying adjacent image parts, wherein the display system furthermore comprises a linking means for linking the driving of the non-pixel addressable light output part of at least the two display devices being arranged for displaying adjacent image parts so that continuity in dynamic range is ensured between the image parts provided by each of the at least two display devices, and wherein the display system furthermore comprises a synchronisation circuit that synchronises the dynamic range of the at least two display devices by determining an overlapping dynamic range common to at least the two display devices arranged for displaying adjacent image parts, and by using this overlapping dynamic range for driving the non-pixel addressable light output parts of at least the two display devices arranged for displaying adjacent image parts.
