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 red light in a red notch band having a full-width half-maximum of not greater than about 50 nm,
• wherein the light-filtering film can be used to reduce light emission passing therethrough over a broad spectrum range of from about 200 nm to about 3000 nm.
