Flat display and method for modulating a clock signal for driving the same

A method for modulating a clock signal for driving a flat display, said flat display having a clock generator and a clock modulator, said method comprising:

• providing said clock signal by said clock generator, wherein said clock signal comprises at least a first cycle waveform and a second cycle waveform immediately following said first cycle waveform;
• and
• modulating said clock signal by said clock modulator, comprising:
• modulating said first cycle waveform as a first modulated cycle waveform made up of a first positive modulated cycle waveform and a first negative modulated cycle waveform;
• and
• modulating said second cycle waveform as a second modulated cycle waveform by made up of a second positive modulated cycle waveform and a second negative modulated cycle waveform and said second positive modulated cycle waveform and said second negative modulated cycle waveform, wherein durations of said first modulated cycle waveform, said second modulated cycle waveform, said first cycle waveform and said second cycle waveform are equal,
• wherein said first positive modulated cycle waveform and said first negative modulated cycle waveform within same said first modulated cycle waveform have a first duration difference, and said second positive modulated cycle waveform and said second negative modulated cycle waveform within same said second modulated cycle waveform have a second duration difference different from said first duration difference.

A flat display, comprising:

• a clock generator providing a clock signal, said clock signal comprising a series of waveform sets, wherein each of said waveform sets comprises at least a first cycle waveform and a second cycle waveform following successively said first cycle waveform;
• and
• a clock modulator modulating said clock signal, wherein each of said first cycle waveforms is modulated as a first modulated cycle waveform made up of a first positive modulated cycle waveform and a first negative modulated cycle waveform, and each of said second cycle waveforms is modulated as a second modulated cycle waveform made up of a second positive modulated cycle waveform and a second negative modulated cycle waveform, and durations of said first modulated cycle waveforms, said second modulated cycle waveforms, said first cycle waveforms and said second cycle waveforms are equal,
• wherein said first positive modulated cycle waveform of each of said first modulated cycle waveforms and said first negative modulated cycle waveform of each of corresponding same first modulated cycle waveform have a first duration difference, and said second positive modulated cycle waveform of each of said second modulated cycle waveforms and said second negative modulated cycle waveform of each of corresponding same second modulated cycle waveform have a second duration difference different from said first duration difference.
