Patent ID: 7646451

Claim:
A pixel array having an illumination device comprising a plurality of main illumination areas subdivided into at least a first and a second sub-illumination area, wherein a luminous element for outputting radiation is arranged on each sub-illumination area, and wherein a beam deflection unit is associated with each main illumination area, the beam deflection unit being designed to deflect the radiation output by the luminous element of the first sub-illumination area into another direction than the radiation output by the luminous element of the second sub-illumination area; wherein the main illumination area is subdivided into one or more main pixel areas, and correspondingly each sub-illumination area is subdivided into one or more sub-pixel areas, such that one of the luminous elements for outputting radiation is arranged on each sub-pixel area, and that one of the beam deflection units is associated with each main pixel area to deflect the radiation output by the luminous element of the first sub-pixel area of the respective main pixel area into another direction than the radiation output by the luminous element of the second sub-pixel area of the respective main pixel area; wherein, behind the plurality of the beam deflection units in the emission direction, there is arranged a transmitting unit comprising an array of modulation pixels and being controllable to selectively transmit the radiation output by the luminous element to adjust the intensity of the transmitted radiation; and wherein exactly one main pixel area is associated with each modulation pixel and vice versa.
