Abstract:
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.
