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.

Abstract: The present disclosure describes a wellness application for digital usage comprising at least one software program that identifies the level of high energy visible light reduction provided by the thin film; and a dosimeter for sending data about ionizing radiation to the software. The software tracks the total time of device usage and determines wherein the software, based on a dosimeter measurement received from the dosimeter, communicates with at least one processor to execute at least one of: determine a notification for reducing exposure to high energy visible blue light about divide user interface, and adjust the display output by at least one of adjusting a color contrast and brightness, taking into account the level of visible light coverage and total time of device usage.

Abstract: A light-filtering film for a screen of a device comprising a polymer substrate. A first absorbing compound combined with the polymer substrate, the first absorbing compound absorbing blue light in a blue notch band having a full-width half-maximum of not greater than about 50 nm. A second absorbing compound combined with the polymer substrate, the second absorbing compound absorbing green light in a green notch, 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.

Abstract: A display system and method are disclosed that includes an electronic display device and a backlight comprising a light-emitting array, a reflector adjacent to the light-emitting array, a diffuser opposite the reflector, a first brightness enhancing layer adjacent the diffuser, and an optical film in the backlight unit that includes at least one light conversion material or at least one light conversion material. The light conversion material is structured and configured to reduce hazardous blue light emissions between about 400 nm to about 500 nm. The disclosed display device can include a liquid crystal panel configured to control transmission of light from the backlight to a viewer. The display device also includes one or more optical films that incorporate one or more light conversion or light absorbing materials. The optical films can be positioned between the layers of the disclosed display device and give enhanced blue-light absorption to the display device.

Abstract: The present disclosure describers a novel combination of a physical filter within an electronic device combined with software to manage the high-energy visible blue light spectrum in accordance with factors including total device use and cumulative intake of blue light. The physical filter may be integrated within layers of the display construction including within the cover glass or polarizer. In preferred embodiments, the physical filter with the software application automatically adjusts the total coverage of blue light emissions relative to each other and the system.
