Abstract

Presented are apparatus, systems and methods for creating tuned color emissions, from lighting and displays, that can be electronically controlled to select a desirable spectrum of wavelengths safer for human vision, for optimal color reproduction, for energy/brightness efficiency, and more. Apparatus including light emitting chips, materials, package design, electronic control devices and circuits, lights, light-fixtures, display panels, visual computing devices and systems, are disclosed. An embodiment is described which is capable of operating in modes, where eye-safe colors are rendered with minimal harmful wavelengths, as well as at least one mode of operation favoring color rendering, and brightness configurations. An embodiment is operable to deliver a paper-like black-on-white viewing experience, in both night-time and day-time operating modes, with reduced high-energy blue-wavelength light spectra. In one embodiment, the light-emitter, controller, display and system are operable to switch between these modes of operation.
