  • 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.

    Abstract: In an eco-friendly method of recycling a fluorescent lamp capable of reducing energy consumption and a recycling apparatus for performing the recycling method, broken pieces of fluorescent lamps are heated at a temperature of about 100? to about 330? to form a gas containing a mercury vapor. The gas containing the mercury vapor is cooled at a temperature of about ?38? to about 0? to form a liquid mercury. The liquid mercury is collected. Therefore, the broken pieces of the fluorescent lamps are heated at the temperature no higher than the boiling point of mercury so that an energy consumption and a size of the recycling apparatus are decreased, and a probability for the recycling apparatus to malfunction may also be decreased.
