  • Patent number: 7880095
    Abstract: A gasket is interposed between a circuit board that generates electromagnetic waves and a conductive member, and includes an elastic member separating the circuit board from the conductive member. The gasket is electrically connected with the circuit board by a conductive layer to receive the electromagnetic waves from the circuit board. The conductive layer is covered with an insulating layer except for a contact area where the conductive layer is coupled with the circuit board. The insulating layer blocks the electromagnetic waves received from the circuit board. The electromagnetic wave noise of a display apparatus is reduced even if a contact failure occurs between the gasket and a top chassis.

  • Publication number: 20080089018
    Abstract: In a gasket and a display apparatus having the gasket, the gasket is interposed between a circuit board and a protective member to transmit electromagnetic waves generated from the circuit board to the protective member. The elastic member separates the circuit board from the protective member. The conductive member surrounds the elastic member and electrically connects the circuit board with the protective member to transmit the electromagnetic waves. The supporting member is provided between the elastic member and the conductive member to support the contact area of the gasket making contact with the circuit board. The adhesive member is provided on the conductive member corresponding to the supporting member to bond the conductive member to the circuit board. Thus, the gasket is not separated from the circuit board, thereby preventing malfunction of the display apparatus.
