  • Patent number: 7522229
    Abstract: A flat-panel display including a body, a base detachably connected with the body, and a metal plate detachably connected with the base is provided in the present invention. When the body is at a first use-state, the metal plate is affixed to the base and supports the body. When the body is at a second use-state, the metal plate is separated from the base and connected with the body to make the body capable of being hung on a wall. Besides, the metal plate also can reduce the electromagnetic interference effectively.

  • Patent number: 6976856
    Abstract: An electronic apparatus for reducing of EMI (Electromagnetic Interference) in an electronic device is provided. The apparatus includes a socket on a printed circuit board of the apparatus and a metal frame placed beside the printed circuit board for grounding purpose. The socket, inserted with a plug connecting to the electronic device, has at least one pin, and the pin is electronically connected to a conductive object on the printed circuit board. The metal frame has a first protrusion pressing against the conductive object, thereby allowing EMI of the electronic device to be grounded.

  • Patent number: 6871964
    Abstract: A projector with a flexible sheet to reduce electromagnetic interference (EMI). The projector has an upper case, a lower case, an optical engine and at least a flexible sheet. The upper case is electrically grounded and connected to the lower case. The optical engine is disposed in the lower case and located between the upper case and the lower case. The flexible sheet is fixed on the optical engine and contacts the upper case to release the noise to ground and reduce the electromagnetic interference (EMI) from the optical engine.
