A light-absorbing, neutral density filter for an electronic device display. More specifically, a light-absorbing, neutral density filter applied as a shield, protective film, or protective coating layer for an electronic device display that blocks ultraviolet light, high energy visible light, and at least a portion of blue light. The neutral density filter comprises a polymer substrate and an absorbing agent.

Light emission reducing compounds for electronic devices

A light-filtering film for a screen of a device comprising a polymer substrate. A first absorbing compound combined with the polymer substrate, the first absorbing compound absorbing blue light in a blue notch band having a full-width half-maximum of not greater than about 50 nm. A second absorbing compound combined with the polymer substrate, the second absorbing compound absorbing green light in a green notch, wherein the first absorbing compound comprises an absorption that has a maximum absorbance peak between about 420 nm and about 445 nm, and wherein the second absorbing compound has a maximum absorbance peak between about 540 nm and 610 nm.

A display device is disclosed that includes a backlight comprising light-emitting diodes. The disclosed display device includes a liquid crystal panel configured to control transmission of light from the backlight to a viewer. The display device also includes one or more optical films that incorporate one or more light conversion materials.

Light emission modification

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 +/&#x2212; 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 +/&#x2212; 1000 Kelvin.
