Abstract:
Device for the dynamic selection of colors and images, wherein it comprises:a polychromatic light beam generator,a plurality of reticulated microlenses arranged in a matrix, integrated in a thin transparent material, said microlenses having the function of generating three beams of color bands centered on a defined wave length, each microlens of the matrix being able to generate many rectangular focused beams focused on respective different areas corresponding to adjacent pixels of an image modulator,a matrix of colored microfilters with transmittance peaks corresponding to the central wave length of the color bands generated by the matrix of reticulated microlenses, having the function of increasing the contrast or improving the separation or eliminating the problems associated with overlapping (cross talk) of the color bands, said microfilters been interposed between the image modulator and the reticulated microlens matrix.
