摘要:
A design for a display apparatus that allows for improved convection for the removal of hot air from heated circuit components. The display apparatus includes a display panel, a chassis having a base, which supports the display panel, and a flange formed along an upper edge of the base to prevent the base from bending, the flange having at least one air passage hole to allow smooth air flow. The display apparatus also has a printed circuit board on which parts for driving the display panel are mounted, the printed circuit board being supported by the chassis, and a case which accommodates the display panel, the chassis, and the printed circuit board. The case also is perforated by two sets of holes to allow hot air to escape and cool air to enter the display apparatus.

Disclosed herein is a method for manufacturing a metal steel separator for fuel cells that has corrosion resistance and contact resistance not only at an initial stage but also after being exposed to high temperature/high humidity conditions in the fuel cell for a long period of time. The method includes preparing a stainless steel sheet as a matrix of the metal separator, forming a discontinuous coating film on the surface of the stainless steel sheet, the coating film being composed of at least one selected from gold (Au), platinum (Pt), ruthenium (Ru), iridium (Ir), ruthenium oxide (RuO2), and iridium oxide (IrO2), and heat treating the stainless steel sheet having the discontinuous coating film to form an oxide film on a portion of the stainless steel sheet on which the coating film is not formed. A metal separator for fuel cells manufactured by the method is also disclosed.

A plasma display device includes a plasma display panel, a chassis base coupled to the plasma display panel, a drive circuit coupled to the chassis base, a flexible printed circuit (FPC) couples the drive circuit to electrodes of the plasma display panel. An integrated circuit (IC) is mounted on a film structured in the form of a tape carrier package (TCP), and coupled to the FPC. An epoxy resin deposited in a connecting region where the driver IC is connected to wiring of the FPC is formed with an uneven area that includes indentations and protrusions formed substantially uniformly.

A plasma display device includes a plasma display panel (PDP). A chassis base supports the PDP from a surface of the same opposite a surface that displays images, and a plurality of driving circuit boards are mounted on the chassis base. A front cabinet is positioned adjacent to the surface of the plasma display panel that displays images. Also, a back cover is positioned adjacent to a surface of the chassis base opposite the surface adjacent to the PDP and is integrally assembled to the front cabinet with the chassis base and the plasma display panel interposed therebetween. The plasma display device also includes thermoelectric semiconductor devices that are mounted within the back cover. The thermoelectric semiconductor devices act to discharge heat generated by the PDP and the driving circuit boards to outside the back cover.
