摘要： A white light-emitting microcavity light-emitting diode device, includes a reflective electrode (12) and a semi-transparent electrode (16) formed over a substrate and an unpatterned white-light-emitting layer (14) formed between the reflective electrode and the semi-transparent electrode, the reflective electrode, semi-transparent electrode, and unpatterned white-light-emitting layer forming an optical cavity. The reflective or semi-transparent electrode is patterned to form independently-controllable light-emitting sub-pixel elements (50, 52, 54, 56). Color filters (40R, 40G, 40B) are formed over a side of the semi-transparent electrodes opposite the unpatterned white light-emitting-layer in correspondence with the light-emitting elements to form colored sub-pixels. At least one light-emitting element has at least two commonly-controlled portions (56Y, 56B) to emit white light to form a white sub-pixel. The white sub-pixel includes optical microcavities (66Y, 66B) tuned to emit light at a different complementary wavelength at an emission angle.

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.

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 method for controlling and compensating aging in an LED device includes measuring a performance change in light output of the LED device. The LED device is controlled with a first compensation algorithm derived from the measured performance change, during a first period, to effect a luminance change over time in the light output of the LED device. Subsequently, a second compensation algorithm, derived from the measured performance change, and different from the first compensation algorithm, during a second period, effects a second luminance change over time in the LED device's light output. The second luminance change over time in the second period is different from the first luminance change over time in the first period. Furthermore, the first and second periods together are less than the lifetime of the LED device.
