The present invention relates to a flat panel display apparatus and a conductive sheet thereof, and more specifically, to a flat panel display apparatus having a conductive sheet extending along a contour of a connector to contact a conductive frame and a conductive sheet thereof.
In general, a circuit board in a flat panel display apparatus usually has connectors for transmitting different kinds of electrical signals, such as AC sockets, ear jacks, D-SUB connectors, DVI connectors, and HDMI connectors. In practical application, for avoiding electromagnetic interference during the signal transmission process, the conventional method involves utilizing an additional ground wire to be electrically connected to a ground pad of the circuit board and a ground terminal of the connector for ground connection of the connector. However, the aforesaid method requires more wiring space and causes a time-consuming and strenuous connector assembly process.
The present invention provides a flat panel display apparatus. The flat panel display apparatus includes a flat panel display device, a conductive frame, a circuit board, a connector, and a conductive sheet. The conductive frame is disposed at a back surface of the flat panel display device. The circuit board is disposed in the conductive frame and electrically connected to the flat panel display device. The connector is disposed on the circuit board and disposed through the conductive frame. The connector has a ground terminal. The conductive sheet includes a connecting sheet portion, at least one ground sheet portion, and a main sheet portion. The connecting sheet portion is connected to the ground terminal. The main sheet portion extends from the connecting sheet portion to the at least one ground sheet portion along a contour of the connector, to make the at least one ground sheet portion be located at a side of the connector and contact the conductive frame for ground connection of the connector.
The present invention further provides a conductive sheet applied to a flat panel display apparatus. The flat panel display apparatus includes a flat panel display device, a conductive frame, a circuit board, and a connector. The conductive frame is disposed at a back surface of the flat panel display device. The circuit board is disposed in the conductive frame and electrically connected to the flat panel display device. The connector is disposed on the circuit board and disposed through the conductive frame. The connector has a ground terminal. The conductive sheet includes a connecting sheet portion, at least one ground sheet portion, and a main sheet portion. The connecting sheet portion is connected to the ground terminal. The main sheet portion extends from the connecting sheet portion to the at least one ground sheet portion along a contour of the connector, to make the at least one ground sheet portion be located at a side of the connector and contact the conductive frame for ground connection of the connector.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Please refer to
As for the related description for structural engagement and ground connection of the connector 18 and the conductive sheet 20, it can be as shown in
To be more specific, in this embodiment, the main sheet portion 26 extends to be connected to the ground sheet portion 24 along a top surface T of the contour C of the connector 18, but not limited thereto, meaning that the present invention could adopt the design in which the main sheet portion extends to be connected to the ground sheet portion along a lateral surface or a bottom surface of the contour of the connector in another embodiment.
In practical application, the flat panel display apparatus 10 could further include a fixing member 28 (e.g. a screw) corresponding to the ground sheet portion 24, and an ear portion 30 is formed on the connector 18 corresponding to the ground sheet portion 24. Accordingly, the fixing member 28 can penetrate the conductive frame 14, the conductive sheet portion 24, and the ear portion 30 (as shown in
To be noted, the contact design for the ground sheet portion 24 and the conductive the frame 14 is not limited to the aforesaid embodiment in which the conductive frame, the ground sheet portion of the conductive sheet and ear portion of the connector are fixed by the fixing member. That is to say, all ground connection designs involving utilizing the ground sheet portion extending from the conductive sheet along the contour of the connector to be located at a side of the connector to contact the conductive frame fall within the scope of the present invention. For example, in another embodiment, the ground sheet portion of the conductive sheet provided by the present invention could be a resilient sheet extending along the contour of the connector and abutting against the conductive frame in a pre-pressing manner. Accordingly, the conductive sheet could directly contact the conductive frame via the ground sheet portion in a surface contact manner for ground connection of the connector without performing any fixing operation, so as to simplify the connector assembly process.
Furthermore, for improving the connection strength between the conductive sheet 20 and the connector 18, as shown in
In summary, compared with the prior art utilizing an additional ground wire to be coupled to a ground pad of the circuit board and a ground terminal of the connector, the present invention adopts the ground connection design that the conductive sheet extends along the contour of the connector to contact the conductive frame. Thus, the present invention can efficiently solve the prior art problem that the wiring method requires more wiring space and causes a time-consuming and strenuous connector assembly process, so as to save the assembly cost of the connector. Further, the present invention can reduce internal space of the flat panel display apparatus needed for ground connection of the connector via the design that the conductive sheet is directly attached to the connector in a surface contact manner, so as to be advantageous to the thinning design of the flat panel display apparatus.
It should be mentioned that the fixing design for the conductive frame, the ground sheet portion of the conductive sheet, and the ear portion of the connector is not limited to the aforesaid embodiment. For example, please refer to
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
