Claim One:
1 ) Multi-MOEMS display, comprising at least one light source; at least a first ( 1 ) and a second ( 2 ) micro mirror array as spatial light modulators, wherein each single micro mirror can be deflected to an OFF-state and to an ON-state, in which the normal ( 102 ) of the mirror includes an ON-deflection angle (β 1 ) with the normal ( 101 ) of the plane ( 100 ) of the first micro mirror array; a first light guidance in which a first incident beam ( 11 ) incides on the first micro mirror array such that the axis of the incident beam ( 11 ) includes an illumination angle (δ) with the normal ( 102 ) of single mirrors of the first micro mirror array in their ON-state, the illumination angle (δ) being larger than the ON-deflection angle (β 1 ), the first ( 12 ) ON-beam, reflected from the surface of the first micro mirror array in the ON-state includes an zenith angle (α) with the normal ( 101 ) to the plane ( 100 ) of the first micro mirror array, the normal projection ( 121 ) of the axis of the first ON-beam ( 12 ) onto the plane ( 100 ) of the first micro mirror array includes an azimuth angle φ, wherein −90°<φ≦+90°, with the rows of the first micro mirror array; a second light guidance in which a second incident beam ( 21 ) incides on the second micro mirror array such that the axis of the second incident beam ( 21 ) includes an illumination angle (δ) with the normal ( 202 ) of single mirrors of the second micro mirror array in their ON-State, which is larger than the deflection angle (β 1 ), the second ( 22 ) ON-beam, reflected from the surface of the second micro mirror array in the ON-state, includes said zenith angle (α) with the normal ( 201 ) of the plane ( 200 ) of the second micro mirror array, the normal projection ( 221 ) of the axis of the second ON-beam ( 22 ) onto the plane ( 200 ) of the second micro mirror array includes an azimuth angle of +φ or −φ with the rows or columns of the second micro mirror array; a superposition system, comprising at least a first superposition layer ( 14 ); an arrangement of the superposition system and of the first and second micro mirror arrays in which the first superposition layer ( 14 ) is configured to reflect a portion ( 15 ) of the first ON-beam ( 12 ), and to transmit a portion ( 25 ) of the second ON-beam ( 22 ), and to reflect the portion ( 15 ) of the first ON-beam ( 12 ) into the same axis in which the portion ( 25 ) of the second ON-beam ( 22 ) transmits it; an arrangement of the superposition system and of the plane ( 100 ) of the first micro mirror array and of the plane ( 200 ) of the second micro mirror array to form a common superposition image in a common plane, whereby the plane ( 100 ) is transformed by at least the reflection at the first superposition layer ( 14 ) to the superposition image plane ( 150 ); projection optics configured to project the superposition image.
