Summary:Double-notch filters for electronic devices are provided that filter light from both the blue spectrum as well as the red spectrum in narrow wavelength bands, or "notches." A double-notch filter can, using input light from a conventional LED-backlit LCD display, output light that can be measured as substantially satisfying criteria for a D65 white point. In some examples, a double-notch filter can output light that can be measured as nearly satisfying criteria for a D65 white point, to within +/− 500 Kelvin. In some examples, a double-notch filter can output light that can be measured as nearly satisfying criteria for a D65 white point, to within +/− 1000 Kelvin.
