摘要： A light-emitting microcavity diode device includes a reflective electrode (12) and a semi-transparent electrode (16) formed over a substrate (10) with an unpatterned light-emitting layer (14) formed between the reflective electrode and the semi-transparent electrode. The reflective electrode, semi-transparent electrode, and unpatterned light-emitting layer form an optical cavity. Either the reflective or semi-transparent electrode is patterned to form independently-controllable, light-emitting sub-pixels (50,52,54,56). Fewer than all, of the sub-pixels emit light through a color filter (40R, 40G). A first sub-pixel (54) emits light having a first primary color and a second sub-pixel (56) emits complementary colored light. The light emitted changes at one or more different angles. The color of the combined light of the first and second sub-pixels changes less at the one or more different angles than the light from the first or second sub-pixels. A third sub-pixel (52) emits light through a color filter (40G) of a second primary color, different from the first primary color.

摘要： A thin-film, white-light-emitting diode device includes a reflective, conductive thin-film structure and a semi-transparent, conductive thin-film structure. One or more thin-film layers are formed between the reflective and semi-transparent conductive thin-film structures to form two or more commonly-controlled microcavity structures. The thin-film layers emit white light in response to current provided by the conductive thin-film structure. Each of the two or more commonly-controlled microcavity structures has a different resonant frequency within one or more optical cavities and emits light with a smaller spectral range than the spectral range of the white-light-emitting thin-film layer(s). A combination of light emitted from the two or more commonly-controlled microcavity structures is white.

摘要： A full-color, light-emitting display device has improved efficiency with a large color gamut. The full-color, light-emitting display device has a plurality of pixels, each pixel having four or more colors of light-emitting elements. Three of the colors of light-emitting elements emits red, green, and blue light, and at least one of the colors of light-emitting elements emitting light is perceived to be within the gamut defined by the chromaticity coordinates of the red, green, and blue colored light-emitting elements. The light-emitting elements for emitting red, green, and blue colors of light each comprise a different species of inorganic light-emitting particles for emitting a different color of light. Each of the red, green, and blue species produces light having an emission spectrum with a full-width, half-maximum of less than or equal to 70 nm.
