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 ( 1 ) 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 ).
