  • Publication number: 20070285598
    Abstract: A polarizing plate includes a base substrate, a conductive lattice pattern and a light absorbing pattern. The base substrate has a first surface and a second surface located opposite to the first surface. The conductive lattice pattern is formed on the first surface in a stripe arrangement. The conductive lattice pattern reflects and/or polarizes light incident on the conductive lattice pattern. The light absorbing pattern is formed on the first surface and corresponds to the conductive lattice pattern. The light absorbing pattern absorbs at least a portion of light reflected on an arbitrary interface after being polarized by the conductive lattice pattern. Thus, an undesired polarization component of a light exiting through a polarizing plate may be reduced, thereby increasing a contrast ratio of a display panel.

  • Publication number: 20070247562
    Abstract: A liquid crystal display (LCD) includes an image display unit, a backlight unit that supplies light to the display unit, and an optical film unit including a diffusion sheet and a prism sheet disposed between the display and the backlight units. The prism sheet includes right angle prisms and acute angle prisms that are greater in height than the right angle prisms, which are formed together in the prism film. The arrangement of prisms enables light that would otherwise be lost inside of the display to be recycled, thereby providing an increase in the efficiency of light use by the display and an increase in the angle at which light exits it.

  • Patent number: 7245015
    Abstract: In a display apparatus, a display panel receives a driving signal from a driving chip through a pad and displays an image in response to the driving signal. The driving chip includes a terminal outputting the driving signal. The driving chip is mounted on the display panel using the anisotropic conductive film and electrically connected to the display panel. A lubricant layer is formed on a surface of the anisotropic conductive film to prevent an electrical defect in the connection between the driving chip and the display panel. Thus, the display apparatus may have improved yield.

  • Publication number: 20070058259
    Abstract: A light-condensing member includes a base plate, a main light-condensing pattern formed on the base plate, and a sub light-condensing pattern formed on the main light-condensing pattern. The main light-condensing pattern includes a plurality of main prisms extended in a first direction. A cross section of a main prism taken along a second direction substantially perpendicular to the first direction has a substantially triangular shape. The sub light-condensing pattern includes a plurality of sub prisms formed on the main prisms and extended in a second direction substantially perpendicular to the first direction. A cross section of a sub prism taken along the first direction has a substantially triangular shape. Since light is condensed simultaneously in both a horizontal direction and a vertical direction through one light-condensing member, manufacturing costs and the thickness of backlight assembly are reduced.
