Abstract

The present invention discloses an source driver circuit scheme for displayer, which comprises a shifter register to register data signal, a line buffer coupled with said shifter register to latch the data signal, a level shifter coupled with line buffer to level output electrical potential, a digital-to-analog converter (DAC) to convert digital signal to analog signal, an output buffer coupled with said digital-to-analog converter (DAC) to output converted signal, and an output control circuit coupled with output buffer. Said output control circuit comprises a D flip-flop and CMOS switching element to output a LP_out signal and control the data signal output of the source driver IC to avoid the power-on noise of the displayer.
