Classification: CPC G  C | IPC C  G

Claim 7:
8. An electronic display device comprising:
a light-emitting display device; and
a filter comprising a polymer substrate,, wherein the filter reduces at least 22% of the energy emitted by the light-emitting display device over a wavelength range of from about 380 nm to about 500 nm,, wherein the filter allows transmission of at least 82% of energy emitted by the diode over a wavelength range of from about 520 nm to about 580 nm and transmission of at least 45% of energy emitted by the diode over a wavelength range of from about 625 nm to about 740 nm, and, wherein the filter allows transmission of no more than 82% of energy emitted by the light-emitting display device over a wavelength range of from about 565 nm to about 580 nm.
