SPECTRALLY TUNED MULTIPLE BANDPASS FILTERS FOR VIDEO DISPLAYS

摘要

An optical band pass filter comprises a plurality of dyes in a polymer matrix, wherein said dyes are adapted to selectively transmit predetermined primary color wavelengths of the visible spectrum (e.g. red, green and blue) and to selectively absorb wavelengths other than said primary color wavelengths. The filter is applied on a color display unit in order to enhance the contrast and the brightness of the images to the viewers.
