Since it must be included, the size is considerably large, and therefore, there is a problem in that it cannot be directly detachably coupled to a computer monitor such as an LCD monitor and occupies a separate use space.

In addition to the size problem, the cost of producing such a conventional TV set-top box is expensive, and there is a problem of lowering the competitiveness.

In order to solve these problems, it is necessary to manufacture a small TV receiving module so that the TV receiving module can be attached to and detached from the display device. Necessity is emerging.

The present invention has been proposed to solve the above problems, and an object thereof is a TV receiving module detachable from a display device such as an LCD monitor, a PDP, and the like, and a TV receiving module for controlling power to be used in a display device in common. It is to provide a power supply control system of a display device having a.

In addition, another object of the present invention is to provide a power supply control system for a display device that can reduce the size of the TV receiving module, and thus can easily attach and detach a small TV receiving module to the display device.
