Abstract: A heat dissipation apparatus for use with a plasma display device and a method of conducting the heat generated in the plasma display panel and the driving ICs of the plasma display device to various surfaces of the device for dissipation to air. A first heat sink is disposed between the plasma display panel and the chassis base. The first heat sink is positioned at a first region where the heat generated from the driver ICs is substantially concentrated. A second heat sink is positioned at a second region between the plasma display panel and the chassis base where the heat generated by the plasma display panel is substantially concentrated. A number of additional thermal conduction media are also used in the various embodiments of the invention.

Abstract: A plasma display apparatus includes a plasma display panel and a chassis base extending substantially parallel to the plasma display panel. The chassis base has a driving circuit mounted thereon in opposition to the plasma display panel. A driver IC faces the chassis base, and is packaged in a film-shaped assembly. A thermal conduction medium is disposed and solidified between the driver IC and the chassis base so as to dissipate the heat generated at the driver IC.

Abstract: Provided is a camera module having a lens with a plurality of IR cut-off filters. The IR cut-off filters are vacuum deposited in a thin film type on surfaces of two aspherical plastic lenses among a plurality of aspherical plastic lenses mounted within the camera module. The height of the camera module can be minimized and the manufacturing cost can be saved because the number of processes is reduced by the reduced number of parts.

Abstract: A display apparatus dissipates heat efficiently from a tape carrier package driver integrated circuit providing an address voltage to a display panel. The display apparatus includes a display panel, a chassis base, a driving circuit, an flexible printed circuit electrically connecting electrodes of the display panel to the driving circuit, and a driver integrated circuit connected through the flexible printed circuit to the display panel, the driver integrated circuit providing a voltage selectively to the electrode of the display panel in accordance with signals controlled by the driving circuit.
