Abstract
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.
Claims12
An electronic display device comprising:
- a light-emitting display device;
- and
- a filter comprising a polymer substrate,
- wherein the filter allows transmission at least 78% of the energy emitted by the light-emitting device over a wavelength range of about 400 nm to about 520 nm, and
- wherein the filter allows transmission of no more than 79% of energy emitted by the light-emitting device over a wavelength range of from about 415 nm to about 455 nm and transmission of no more than 45% of energy emitted by the light-emitting device over a wavelength range of from about 625 nm to about 740 nm.

An electronic display device comprising:
- a light-emitting display device;
- and
- a filter comprising a polymer substrate,
- wherein the filter allows transmission of no more than about 1% of energy emitted by the light-emitting device over a wavelength range of from about 380 nm to about 400 nm, and at least 66% of the energy emitted by the light-emitting device over a wavelength range of from about 400 nm to about 520 nm, and
- wherein the filter allows transmission of no more than 64% of energy emitted by the light-emitting device over a wavelength range of from about 415 nm to about 455 nm and transmission of no more than 52% of energy emitted by the light-emitting display device over a wavelength range of from about 625 nm to about 740 nm.
