摘要： Color may be achieved in TIR-based image displays by addition of a sub-pixel color filter array (CFA). Color may be enhanced by tuning the size, shape, arrangement and colors of the sub-pixel color filters in the CFA. CFAs comprising of pixels further comprising one to four or more different repeating sub-pixel color filters may be capable of creating a wide gamut of displayable colors. The sub-pixels may be arranged in repeat cells wherein the sub-pixels within the repeat cell may be mapped to one or more pixels. Sub-pixel rendering may be used during driving of a TIR-based display. Sub-pixel rendering uses logical dynamic pixels where a single sub-pixel may be used in one or more pixels depending on the image displayed.

摘要： A display device includes a substrate, at least three light emitting elements and a light adjusting layer. The light adjusting layer includes at least one light adjusting structure and is disposed on the light emitting elements. One light adjusting structure is corresponding to the light emitting elements. The display device provides a sum of viewing-angles of a first number of the light emitting elements when the first number of the light emitting elements is turned on, and the display device provides a sum of viewing-angles of a second number of the light emitting elements when the second number of the light emitting elements is turned on. The first number is less than the second number, and the sum of viewing-angles of the first number of the light emitting elements is less than the sum of viewing-angles of the second number of the light emitting elements.

摘要： 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.
