ABSTRACT:
Improved digital projection systems and methods are disclosed. Exemplary systems and methods embody a digital data source and a white light source. Light output of the white light source is coupled to a two-position digital micro-mirror device that separates black and colored pixels. The reflected color pixels output of the two-position digital micro-mirror device are coupled to a diffraction micro-lens array that diffracts the colored pixels to produce partial spectrum color bands. The diffracted partial spectrum color bands output of the diffraction micro-lens array is coupled to a three-position digital micro-mirror device that produces hue of each pixel. Micro-mirrors of the two- and three-position digital micro-mirror devices are controlled by the digital output of the digital data source. The output of the three-position digital micro-mirror device is coupled to projection optics that combines the partial spectrum color bands and projects an image.
