Abstract
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.
