摘要： The specification and drawings present a new method, apparatus and software product for dynamically adjusting a color gamut of a display (e.g., a field sequential color display) and further adjusting a luminance of the display in an electronic device by adjusting and turning on field duties of primary colors. During each color field, the other primary colors of light sources supporting the display can be turned on at their respective fractions of their color field. These fractions can be continuously tunable in order to control the color coordinate of each primary color dynamically thus adjusting the color gamut and the luminance of the display.

摘要： A light modulating apparatus includes a semiconductor device having a quantum well structure and a device for applying an electric field to the quantum well structure of the semiconductor device. Both of pump and probe light beams or a pump and probe light beam is input into the semiconductor device. The pump light beam or pump and probe light beam received by the semiconductor device causes a real charge excitation in the quantum well structure, and the real charge excitation screens the electric field applied to the quantum well structure. The polarization state of the probe light beam or pump and probe light beam emerging from the semiconductor device is changed by an electrooptical effect in the quantum well structure induced by the real charge excitation. A polarizer may be disposed for converting a change in polarization state of the light emerging from the semiconductor device into a change in intensity of the light.

摘要： The specification and drawings present a new method, apparatus and software product for increasing a grey dynamic range of a display for displaying video data by providing a grey level, calculated for a reduced number of primary colors using a predetermined criterion, for each field of a frame set by the display by varying an amplitude or a subfield composition of a display driving signal and by varying a fluence of simultaneously lit backlight sources (e.g., LEDs) corresponding to selected two or more primary colors of the display. Thus, grey level resolution of the display can be increased to match the higher grey level resolution of the video data provided to the display.

摘要： A method and an apparatus for spectrum synthesis for use in a flash unit, wherein the spectrum synthesis includes combining a plurality of emissive light sources in order to provide a combine output beam and producing the output spectrum for the combined output beam at least based on a reference spectrum. The reference spectrum can be obtained by sensing the spectrum of ambient light or selected from a plurality of stored spectra. The flash unit has at least two emissive light sources and each of the light sources can be adjusted relative to each other so that the outputs from the light sources can mimic a selected illumination scenario. It is possible to use a mixture of quantum dots to tailor each light source so that the combined spectra from different light sources can reasonably mimic a number of frequently used illumination scenario.
