摘要
Disclosed in this invention is an optical filter to enhance the contrast and brightness of images from a color display. The filter comprises suitable dyes and a polymer matrix, applied in a suitable form on the display unit. 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. Such filters have utility in devices based on CRTs, plasmas and the like.
