ABSTRACT:
An electromagnetic interference (EMI) prevention apparatus for a flat panel display which is capable of modulating the frequency of an input clock signal using a spread spectrum clocking method to increase the frequency of the clock signal and reduce the amplitude thereof so as to reduce EMI by a clock signal generated from a format converter of the flat panel display. The amount of electromagnetic energy radiated from a signal source of the flat panel display can be reduced to eradicate the root of an EMI problem, thus excluding the use of a conventional shielding plate or device.
