Abstract
A bandpass filter containing specific combinations of the dyes to yield filters which are adapted to selectively transmit predetermined primary color wavelengths of an electromagnetic spectrum as well as selectively absorb wavelengths other than the predetermined primary color wavelengths. The multiple bandpass filters are employed to improve the images on CRT screens and plasma display panels.
Claims29
A bandpass filter for contrast and color enhancement of a video monitor comprising a dye having substantially the absorbance spectrum as shown in FIG. 1, a dye having substantially the absorbance spectrum as shown in FIG. 2, Rhodamine 101, IRA 850, and Luxol Fast Blue MBSN, uniformly incorporated in a polymer matrix.
A color display device comprising:
- a face plate having an inner surface and an outer surface, the inner surface containing a phosphor layer;
- and a translucent filter on the outer surface of the face plate;
- the filter comprising a dye having substantially the absorbance spectrum as shown in FIG. 1, a dye having substantially the absorbance spectrum as shown in FIG. 2, Rhodamine 101, IRA 850, and Luxol Fast Blue MBSN uniformly incorporated in a polymer matrix.
