Abstract: An expansion card module is provided. The expansion card module is adapted for being assembled to a circuit board. The circuit board includes a connector and a fixing unit. The expansion card module is fixed between the connector and the fixing unit. The expansion card module includes an expansion card and a shielding plate. The expansion card has an end plugged in and electrically connected to the connector. The shielding plate includes a first portion and a second portion. The first portion covers a part of the expansion card. The second portion extends to an outside of the other end of the expansion card, and is fixed by the fixing unit.

Abstract: An expansion card including a board is provided. The board has a chip module and a notch that is breakable. The notch divides the board into a first region and a second region, and the chip module is located in the first region.

Abstract: A television box suitable for being coupled to a display is provided. The television box includes a chip and a transmitter. The chip supports to output a low voltage differential signal. The transmitter is coupled to the chip and selectively transmits the low voltage differential signal output by the chip to a digital visual signal or an analog visual signal. The television box has the advantages of noise reduction and color enhancement.
