Abstract:
The invention relates to a method of manufacturing a microprojector for a projection display, wherein the microprojector comprises a support on which a projector lens array with a plurality of projector lenses is arranged, wherein on a side of the support facing away from the projector lens array, an object structure array with a plurality of e.g. identical object structures is arranged, wherein at least one projector lens is associated with one object structure such that the projections of the object structures superpose through the projector lenses to form a full image, wherein e.g. the distance between a projector lens and the associated object structures corresponds to the focal length of the respective projector lens, wherein on the object structure array, a condenser lens array is arranged such that in case of an illumination of the condenser lens array, a Köhler illumination of the object structures or projector lens associated with the respective condenser lenses is permitted.
