Abstract

A display system comprising a backlight device having a light emitting array, a liquid crystal panel, and a color filter having one or more absorbing dyes and, optionally, one or more dye enhancement compounds, wherein the one or more absorbing dyes and the one or more dye enhancement compounds are located in at least one color set of subpixels in the color filter. The one or more absorbing dyes may be a soluble, blue light, green light, or red light absorbing dye included in blue, green, or red subpixels of the color filter. A blue light absorbing dye may reduce transmission in a wavelength range of 410-430 nm, a green light absorbing dye may reduce transmission in a wavelength range of 490-570 nm, and a red light absorbing dye may reduce transmission of wavelengths less than 620 nm.
