  • Patent number: 7742031
    Abstract: A display device includes: a gate driver for carrying out display scanning on pixels sequentially in a first direction of a TFT liquid crystal panel so as to set pixels to display states thereof according to information to be displayed by the pixels in the TFT liquid crystal panel. The pixels being arranged in two dimensions and being individually controllable in terms of the display state through illumination. There is a backlight, unit for illuminating the individual pixels with intensity of light which increases and subsequently decreases in synchronism with the display scanning carried out by the gate driver, but only after the display scanning. The arrangement enables the backlight flashing period to be determined independently from a TFT panel scanning period or response time of liquid crystal, ensures an extended operating time of a TFT panel, effects a display period equal to, or longer than, the black blanking type, and achieves higher contrast than the black blanking type.

  • Publication number: 20100148120
    Abstract: A light-emitting apparatus composed of a light source that emits primary light and a phosphor that absorbs the primary light and emits secondary light offers high brightness, low power consumption, and a long lifetime while minimizing adverse effects on the environment. The phosphor is formed of a III-V group semiconductor in the form of fine-particle crystals each having a volume of 2 800 nm3 or less. The light emitted from the fine-particle crystals depends on their volume, and therefore giving the fine-particle crystals a predetermined volume distribution makes it possible to adjust the wavelength range of the secondary light.
