Patent ID: 11295680

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, retaining or enhancing color-integrity, for a more seamless user experience, optimizing power efficiency and safety.Embodiments include LED-backlit LCD's, organic light emitting diodes (OLED), Micro-LED, ePaper (reflective displays), and light sources are described. Additionally, the methods of construction, materials, electrical drive, pixel color adjustment, and modes of system operation are described, such that one of ordinary skill in the art could construct an apparatus capable of operating in eye-safe, bright and colorful modes of operation, are also included.
