The invention relates to a projection system comprising an active display (1, 1'). The display comprises radiation-sensitive control units (4) which decode the information about brightness and color of a pixel in the signal beam (I) of a projector (2) and drive connected light-emitting diodes (3) accordingly. Due to the self-sufficient mode of operation of these pixels, it is possible to build up comparatively flat and large-sized projection faces whose brightness is not limited by the capacity of the projector (2).
