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.

Abstract: Presented herein are methods for creating nanoparticles, which exhibit desirable electro-luminescent and photo-luminescent capabilities, while retaining the robust inorganic nature. And incorporating the nanoparticles in micron and sub-micron scale structures, via a range of patterning techniques, to create highly functional meta-material apparatus. Example embodiments include applications in emissive color elements within displays, Micro-LED devices, and thin-film apparatus; integrating optical, photonic and plasmonic properties, from the combination of patternable nano-scale features, with photo/electro-luminescing material capabilities; performing multiple light processing functions, within the apparatus. The method of construction, materials, electrical drive, color and pixel manipulation as well as system integration are described, such that one of ordinary skill in the art could construct implementations including lighting, displays, panels and other applications.

Abstract: A reflective filter serving as a multi-bandpass filter for a light source configured to emit light in a plurality of color primary wavelengths to improve color purity. The addition of a reflective/recirculation assembly reinforces and recirculates light not passed by the multi-bandpass filter back into a desired spectrum, which is subsequently passed by the multi-bandpass filter, or converts light not passed by the multi-bandpass into electrical energy for use by the system. The reflective filter, solely or along with the recirculation assembly, can be placed adjacent a conventional light source. Alternatively the multi-bandpass filter and the recirculation assembly can be placed in a modified light source, or placed in an optical stack along the path of light emission. Collimating structures that enforce the light into desired incident angle of attack onto the reflective filter can be included to enhance the efficiency of the reflective elements in the assembly.
