  • Patent number: 8053961
    Abstract: The present invention is related to a color-mixture display unit and an image display apparatus using the same, wherein the image display apparatus includes at least one color-mixture pixel which is pre-disposed at plates of a light box so that a pattern is formed. Each of the color-mixture pixels is equipped with a red filter, a green filter and a blue filter, or equipped with a black filter or equipped with a transparent filter. At least one color-mixture LED is disposed within the light box and provides a backlight for the color-mixture pixel. In this regard, the color-mixture LEDs are controlled by an image controller and provide various color light beams with the color-mixture pixels. In addition, arrangement of each color filter within the color-mixture pixel is utilized so that color-mixture effect of dynamic image is shown.

  • Publication number: 20110006973
    Abstract: The present invention relates to the display field, and provides a LED display device. The LED display device comprises a data acquisition unit configured for acquiring image data; a data conversion unit configured for performing a data-conversion operation for the image data; and a LED display unit configured for displaying data converted by the data conversion unit. The LED display unit comprises a plurality of LED groups consisted of red LEDs, green LEDs, blue LEDs and white LEDs. The LED display device of the present invention employs the LEDs with four colors to compose a pixel, and employs the white LED to emit white light configured for replacing the white light formed by blending RGB light. Thus the LED display device reduces the power consumption and saves the energy.

  • Patent number: 7696990
    Abstract: The present invention relates to an LED driving circuit and a serial LED illumination system. The LED driving circuit compares a data signal with a voltage threshold via a comparator to output a mode selection signal. The register unit includes an instruction register and a data register. The register unit is coupled to the comparator unit and controlled by the mode selection signal to perform an instruction or data transmission mode. The instruction register stores the instruction data under the instruction mode. The data register stores the illumination display data under the data transmission mode. When the data register is full, the register unit outputs a secondary data signal. The driving unit is controlled by the instruction data and drives an LED module according to the illumination display data. The serial LED illumination system includes a controller that is connected with at least one LED driving circuit in serial.

  • Patent number: 7614766
    Abstract: A modular illumination device with adjustable illumination modules includes a substrate, a rotating element, a reflective element, an adjustable element, and a light-emitting element. The rotating element is rotatably disposed on the substrate and rotates corresponding to the substrate. The reflective element pivots on the rotating element and pivots corresponding to the substrate. The adjustable element is moveably disposed on the substrate and is moved corresponding to the reflective element. The light-emitting element is disposed on the adjustable element. The modular illumination device can be adjusted to shine light at any angle or in any direction. Furthermore, a plurality of illumination modules are combined to form the modular illumination device. By adjusting the lighting range and direction of the illumination modules respectively, the illumination device has different illumination ranges.
