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 to an electronic device display or incorporated into the screen layers of a device 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.
Claims20
A light-filtering film comprising:
- a polymer substrate;
- and
- at least one light absorbing compound,
- wherein, for light emitted by a display device and transmitted through the light-filtering film,
- the film reduces at least 22% of the energy emitted by the light-emitting display device over a wavelength range of from about 400 nm to about 500 nm,
- the film allows an average 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,
- the film allows an average transmission of at least 74% of energy emitted by the light-emitting display device over a wavelength range of from about 580 nm to about 625 nm, and
- the film allows an average transmission of at least 45% of energy emitted by the light-emitting display device over a wavelength range of from about 625 nm to about 740 nm.
