Patent number: 7944682Abstract: A gasket includes an elastic member absorbing an external shock, a conductive member surrounding the elastic member, and a reinforcing member disposed within the conductive member and extending along a bottom surface and a side surface of the conductive member. A screen spacer includes an elastic member absorbing an external shock, and a reinforcing member disposed on one side of the elastic member. A display device includes a driving circuit substrate supplying a driving signal to a display panel, a chassis receiving the display panel and the gasket attached to the driving circuit substrate and contacting the chassis, the gasket grounding the driving circuit and the chassis.Type: GrantFiled: July 8, 2008Date of Patent: May 17, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Dong-Joon Park, Ha-Yun Kang, Gun-Ho Kim, Duk-Hwan Kang, Jae-Kook Kim

Patent number: 7880095Abstract: 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.Type: GrantFiled: September 21, 2007Date of Patent: February 1, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Ha-Yun Kang, Gun-Ho Kim, Jae-Kook Kim

Publication number: 20080089018Abstract: 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.Type: ApplicationFiled: September 21, 2007Publication date: April 17, 2008Inventors: Jae-Kook KIM, Ha-Yun Kang
