Abstract:
A method of processing signals by a system,said system comprising: a display device; an active matrix portion being formed over a first substrate; a source side driver circuit portion over the first substrate; a gate side driver circuit portion over the first substrate; at least a terminal for transmitting an external signal to the source side driver circuit portion and the gate side driver portion, said terminal being formed over the first substrate; at least an IC chip portion being formed over the first substrate; an A/D converter being formed in the IC chip portion; a VRAM being formed in the IC chip portion; a correction+tone reverse circuit being formed in the IC chip portion; a D/A converter being formed in the IC chip portion; a clock generator being formed in the IC chip portion; a controlling microcomputer being formed in the IC chip portion; said method comprising the steps of: externally transferring an analog signal; outputting the analog signal through the A/D converter, the VRAM, the correction+tone reverse circuit and the D/A converter; generating at least one of a clock pulse or a start pulse in the clock generator being based on a horizontal synchronizing signal and a vertical synchronizing signal; transferring at least one of the clock pulse or the start pulse to the A/D converter, the VRAM, the correction+tone reverse circuit and the D/A converter; outputting the analog signal to the source side driver circuit portion.
