摘要:
The present invention relates to color tuned holographic multicolor optical elements for use as multicolor transmission filters in liquid crystal displays and methods of making the elements. The element comprises at least first and second pixel volumes containing holographic mirrors and preferably third pixel volumes containing holographic mirrors. Each set of pixel volumes passes a different color wavelength band and reflects other color wavelength bands.
