The present invention relates to a display device, and more particularly, a first circuit block capable of transmitting and receiving data through a network, and a second circuit block for processing data transmitted and received through a network. The present invention relates to a display device mounted on a printed circuit board.

In general, display devices such as an LCD (Liquid Crystal Display) and a Plasma Display Pen (PDP) are used to display images in various fields such as TVs or computer monitors.

Generally, a monitor to which such various functions are added is called a multi function monitor.

Meanwhile, current monitors and computers are connected to each other through a D-Sub connector or a DVI connector so that video signals from the computer are transferred to the monitor.

In addition, in the case of a multi-function monitor, in addition to the D-Sub connector or the DVI connector, a video signal from an external video device such as a DVD or a VCR is also provided by separately providing an S-video connector, a component connector, or a composite connector. It supports receiving.

In addition, even in the case of a computer, only one output connector such as a D-Sub connector is supported, and a trend is to support two or more output connectors such as a D-Sub connector, a DVI connector, and an S-video connector. Two or more monitors can now be connected.
