Abstract
A light-absorbing, neutral density filter for an electronic device display having a capacity grid layer. More specifically, a light-absorbing, neutral density filter applied as a protective film or protective layer to an electronic device display or incorporated into or onto the screen layers of a device that can block ultraviolet light, high energy visible light, a portion of blue light, and/or other light in the visible spectrum. The neutral density filter comprises a polymer substrate and an absorbing agent.
Claims22
An electronic display device comprising:
- a light-emitting diode display device;
- a capacity grid layer;
- and
- a neutral density filter comprising
- an organic dye, and
- a polymer substrate selected from the group consisting of polycarbonates, PVCs, epoxies, polyesters, polyethylenes, polyamides, and combinations thereof,
- wherein
- the neutral density filter blocks at least a portion of the ultraviolet wavelength range, and
- the neutral density filter includes an absorption peak in the wavelength range between 400 nm and 500 nm or between 530 nm and 630 nm.
