    Abstract: The present application is directed to an illumination device comprising a recycling cavity defined by recycling surfaces and a light emission surface; a light source within the cavity. A spectrum modifying layer is on a portion of the recycling surface, the spectrum modifying layer producing a spectral response different from the spectral response of the recycling surface. In some embodiments, the spectrum modifying layer shifts the spectral properties of the light being emitted from the light emission area from the spectral properties of the light source. In some embodiments, the spectrum modifying layer selectively absorbs a portion of light along the light source spectrum. In some embodiments, the spectrum modifying layer re-emits light at a wavelength longer than the wavelength it absorbed.

    Abstract: Modular displays and methods of assembling modular displays are disclosed. The displays include a display element and a base element. The base element includes a light source configured to inject light into the display element, and electronics to drive the display element when the display element is attached to the base element. The display element includes a lightguide and a display panel, such as a liquid crystal display (LCD) panel. The base element further includes a receptacle configured to accept the display element and couple the light source to the lightguide, and couple the electronics to the LCD panel. The display element and the base element can be removably attached to each other. The base element and the display element can each be configured so that different display elements can be attached to the same base element, providing flexibility of modular display design.

    Abstract: Collimating light engines, methods of making collimating light engines, and articles incorporating collimating light engines are disclosed. In one aspect, a light source and circuitry can be disposed between a reflector and a reflective baffle to form a collimating light engine. The light source is at least partially obscured from view by the reflective baffle. Light emitted from the light source is partially collimated upon leaving the light engine. Light uniformity of the output surface of a backlight can be improved by disposing an array of the collimating light engines in the backlight
