摘要： A color/color temperature tunable light emitting device comprises: an excitation source (LED) operable to generate light of a first wavelength range and a wavelength converting component comprising a phosphor material which is operable to convert at least a part of the light into light of a second wavelength range. Light emitted by the device comprises the combined light of the first and second wavelength ranges. The wavelength converting component has a wavelength converting property (phosphor material concentration per unit area) that varies spatially. The color of light generated by the source is tunable by relative movement of the wavelength converting component and excitation source such that the light of the first wavelength range is incident on a different part of the wavelength converting component and the generated light comprises different relative proportions of light of the first and second wavelength ranges.

摘要： Reflective, low-cost display pixels and displays incorporating magneto-optical elements wherein an externally applied magnetic field is perpendicular to an axis of rotation of the magneto-optical elements and parallel to a viewing plane of a display made from these elements. The display elements have a restricted rotation about their long axis which can be actuated by an external magnetic field to produce a bistable, electronically writable image. In addition, architectural modifications to this arrangement can be made such that the power required to write the image to such a display is decreased, overall display efficiency is increased and cross-talk between pixels is nearly eliminated.

摘要： Reflective color displays. Each pixel or sub-pixel of the display preferably comprises at least one magneto-optical element that can rotate in more than two stable positions, displaying a color corresponding to each position. Thus each element can display more than one color (in addition to black, if desired). Multiple elements may be combined to form a sub-pixel and/or pixel. The displays are preferably highly light reflective and preferably have low power consumption and increased resolution.
