  • Patent number: 7358934
    Abstract: In an FED (Field Emission Display), lowering of a color temperature is suppressed which is caused by that light emission luminance of respective color phosphors is different from each other so as to achieve a better white balance. A display apparatus is equipped with a cathode substrate containing a plurality of electron emitter elements, and an anode substrate. The anode substrate is arranged opposite to the cathode substrate, and contains three colors of red, green, blue phosphors which are excited by electrons emitted from the electron emitter elements so as to emit light. Then, an area of either the red phosphor or an area of the blue phosphor is made smaller than an area of the green phosphor.

  • Patent number: 7315114
    Abstract: A display apparatus includes a face plate that constitutes a part of a vacuum envelope, a phosphor layer formed on an inner surface of the face plate, and an electron beam source that emits electron beams to the phosphor layer. The face plate includes a light-emitting glass layer containing a light-emitting substance that emits light when electron beams are projected thereon. By extracting energy of electron beams, which have reached the face plate, as light, it is possible to reduce browning that occurs in the face plate and improve brightness of a display image significantly.

  • Patent number: 6191649
    Abstract: A quadrature demodulator detects a phase angle error determined from the phase angle supplied from constellation symbols of outgoing in-phase and quadrature components of a modulated signal and and the phase angle of a NCO. The quadrature demodulator comprises a receiving circuit for receiving a quadrature modulated signal, and a local oscillator for generating a local carrier. A complex multiplier demodulates the quadrature modulated signal by complex-multiplying the quadrature modulated signal with the local carrier generated in the local oscillator. A symbol error detector detects a symbol error between the carrier of the modulated signal and the local carrier supplied from the signal demodulated at the complex-multiplier. A feedback loop controls the local carrier generated at the local oscillator by feeding back the symbol error detected at the symbol error detector to the local oscillator.
