  • Publication number: 20060044779
    Abstract: In a backlight assembly and a liquid crystal display apparatus, the backlight assembly has lamps parallel to each other to emit a light, a receiving container having a bottom portion and a side portion to receive the lamps, and a mold member coupled to the receiving container to cover the ends of the lamps. The mold member has a reflecting face having a diffusion pattern that reflects the light from the lamps and an upper face extending from the reflecting face in a plane substantially parallel to the bottom portion. Thus, a shadow portion of the backlight assembly may be removed, to thereby enhance image display quality of the liquid crystal display apparatus.

  • Publication number: 20050248936
    Abstract: There is provided a lamp fixing holder. A lamp fixing holder for fixes a lamp to a receiving container. The lamp provides a liquid crystal display panel with light. The lamp includes a first portion of a face and a second portion of the face. The light emitted from the first portion of the face advances toward the liquid crystal display panel. The lamp fixing holder comprises a lamp fixing body and a fixing member. The lamp fixing body holds a third portion of the face of the lamp. The second portion includes the third portion. The fixing member fixes the lamp fixing body to the receiving container. The lamp fixing holder according to the present invention fixes the lamp so that the lamp does not sway, while minimizing an amount of light that is shielded by the lamp fixing holder.

  • Patent number: 6857759
    Abstract: Disclosed is a backlight assembly and an LCD apparatus having uniform brightness and low power consumption. The backlight assembly has a plurality of lamps for providing light to the LCD panel. Each of the plurality of lamps has two or more sub-lamps connected to each other in series. The backlight assembly has a brightness control unit disposed between the sub-lamps to reduce a brightness difference.

  • Publication number: 20040008524
    Abstract: Disclosed are a backlight assembly and a liquid crystal display device using the same. A ratio of a pitch, which is an interval between the lamps for supplying light to an LCD panel, to a gap, which is a distance between the center of the lamps and an optical plate, is adjusted to thereby minimize the bright line that badly influences the image display quality, so as to display a high quality image.

  • Publication number: 20010038079
    Abstract: Disclosed are a method and an apparatus for irradiating low energy ion beam on polymer. The method prepares polymer products having a surface electric conductivity range, in surface electric resistance, from 106 to 1011 &OHgr;/sq, by vacuum-irradiating the ions under relatively low energy of 50-100 keV from ion sources which generates high-current ions of several tens mA or higher, to polymer materials, such as PPO and MPPO, which are electrically insulator; precisely controls temperature so as not to thermally deform molecular configuration of the polymers; produces the products with uniform and stable conductivity in a large area; and treats the surface which improves surface hardness and modifies mechanical properties. Further, the mass-production apparatus for irradiating the ion beams is capable of commercially realizing said method. Accordingly, ions, inert gases (nitrogen, oxygen, argon, xenon, helium, etc.
