Light emission reducing compounds for electronic devices

A method for light-filtering for a screen of a device comprising:

• having a film on a light emitting display, wherein the film reduces transmissivity by:
• having a polymer substrate and a first absorbing compound combined with the polymer substrate;
• absorbing, by the first absorbing compound, blue light in a blue notch band having a full-width half-maximum of not greater than about 50 nm;
• and
• absorbing green light in a green notch by a second absorbing compound combined with the polymer substrate,
• 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.

• 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 comprises an absorption that has a decrease of light transmission absorption by about 10% to about 25% between the range of about 520 nm and 680 nm.
