Patent ID: 7973780

Claim:
An electromagnetic interference prevention apparatus for a flat panel display comprising: clock generation means for generating a clock signal; spread spectrum clocking means for modulating the clock signal generated by the clock generation means such that the clock signal is frequency modulated between a nominal frequency (fnom) of the clock signal and a down spreading frequency (1−δ) fnom, where δ represents a spreading magnitude as a percentage of the nominal frequency (fnom), a frequency of the clock signal generated by the clock generation means being modulated according to a modulation profile to reduce an intensity of EMI, the modulation profile having a predetermined frequency; and data processing means for synchronizing the clock signal modulated by the spread spectrum clocking means with an input clock signal at the predetermined frequency and outputting input data as a signal of the predetermined frequency, wherein the data processing means is a format converter being adapted to receive the modulated clock signal from the spread spectrum clocking means as a reference clock signal for a phase lock loop therein and output a modified clock signal synchronized with input data.
