Abstract:
A light-emitting device (52, 80, 110, 128, or 130) suitable for a flat-panel cathode-ray tube display contains a light-emissive region (66) formed over a plate (64). The light-emissive region contains a plurality of light-emissive particles (72). Part of the outer surface of each light-emissive particle is conformally covered with one or more coatings (74, 82, 84, 112, and 114). The coatings variously provide light-reflection, gettering, intensity-enhancement, and contrast-enhancement functions.
Abstract:

Abstract:
A cathodoluminescent device, including a luminescent layer having a first side, called the front side, that is intended to receive incident electrons, the luminescent layer being suitable for absorbing incident electrons and for emitting light radiation in response, wherein the front side of the luminescent layer is coated with a layer including electrically conductive nanowires.
Abstract:
A solid state lighting luminaire, which comprises a solid state light source, an encapsulated structure, and a first phosphor, is provided. The encapsulated structure encapsulates the solid state light source and has an outside illuminating surface. The first phosphor is patterned to cover a portion of the outside illuminating surface for down-converting the illumination from the solid state light source.
Abstract:
A display device free from a deterioration in luminescence efficiency is provided. In the display device of the present invention, since an inorganic film is formed after concave parts in which luminescence portions are positioned are filled with a filling film, no crack is formed in the inorganic film. Since the inorganic film is made of a material having high gas tightness and heat conductivity (such as, diamond-like carbon or AlN), water and oxygen will hardly penetrate the luminescence portions, and heat of the luminescence portions will be conducted to the inorganic film, so that the luminescence portions do not reach high temperatures. Further, since a gap between first and second panels is filled with a resin film, the atmosphere does not enter from the outside. Because the luminescence portions are free from damage from water, oxygen and heat, the display device of the present invention has a prolonged life.
Abstract:
An electroluminescent (EL) device having an LED formed on a substrate with at least two electrodes formed over the substrate, and an EL unit formed between the electrodes. At least one of the electrodes is transparent. At least one of the electrodes is patterned to define independently controllable light-emitting areas. A cover is formed over the LED. The cover or substrate is transparent. A light-scattering layer is formed between the cover and substrate for scattering light. A low-index element, having an optical index lower than other optical indices, is formed between the scattering layer and the transparent cover or substrate. Additionally, a contrast-enhancement layer includes alternating light-absorbing portions and light-transmissive portions formed in the layer located between the light-scattering layer and the transparent substrate or cover through which light is emitted, wherein the light-absorbing portions and light-transmissive portions are located in each light-emitting area.
