ABSTRACT:
On a computer body side, there is provided a low voltage parallel-serial conversion circuit for converting R, G and B digital parallel signals of a first potential, which are output from a display controller, to serial signals of a second potential lower than the first potential and converting a display clock signal and a control signal (FP, LP, DATA ENAB) each having the first potential to a clock signal and a control signal (FP, LP, DATA ENAB) each having the second potential. On a display apparatus side, there is provided a low voltage serial-parallel conversion circuit for converting the second-potential R, G and B signals, which are output from the low voltage parallel-serial conversion circuit, to parallel R, G and B signals of the first potential and restoring the second potential clock signal and control signal (FP, LP, DATA ENAB) to the first-potential clock signal and control signal (FP, LP, DATA ENAB). The display color signals, clock signal and control signal output from the low voltage serial-parallel conversion circuit are supplied to a flat panel.
