  • Patent number: 8331799
    Abstract: A non-feedback pre-encoder for optical DQPSK modulation includes four differential encoders, two power splitters, two delay lines, one exclusive OR gate and a cross switch. Each of two data streams input to the pre-encoder is divided into two identical streams by one of the power splitter, called an upper stream and a lower stream, respectively. Every upper stream is differentially encoded by one of the differential encoders, and outputs of the differential encoders are fed into the XOR gate. An output of the XOR gate drives the cross switch as a control signal. Two lower input data stream are delayed in the delay lines, and fed into the cross switch. The outputs of the cross switch are differentially encoded, separately, where outputs of the pre-encoder are provided. The invention eliminates the speed limitation due to the electrical propagation by constructing an all-forward control signal.

    Abstract: A photoluminescence color display comprises a display panel that displays red, green and blue pixel areas, an excitation source operable to generate excitation radiation for operating the display, and a photoluminescence color-element plate. The color-element plate comprises at least one photoluminescence material, such as a phosphor material or quantum dots, that is operable to emit light corresponding to red, green and blue pixel areas of the display in response to said excitation radiation. Additionally, the photo-luminescence color display comprises a wavelength selective filter that is provided between the color-element plate and the excitation source. The filter has a transmission characteristic that allows the passage of excitation radiation from the excitation source to excite the at least one photoluminescence material whilst preventing the passage of photoluminescence light back to the excitation source thereby prevent cross contamination of light among the different pixel areas of the display.

  • Patent number: 7985000
    Abstract: A lighting apparatus includes a combination of LED dice that emit light of a first color and a wavelength-shifting material (e.g., phosphor) that converts light of the first color to light of a second color. An appropriate combination of light of the first color and light of the second color can be used to produce light of a target color. In an embodiment, LED dice in the lighting apparatus are divided into two groups. Each LED die in the first group is combined with less wavelength-shifting material than needed to produce light of the target color, while each LED die in the second group is combined with more wavelength-shifting material than needed to produce light of the target color. As a result, the two groups produce light having colors on opposite sides of the target color in the International Commission on Illumination (CIE) chromaticity diagram.
