Abstract

In this paper, we propose a mixed driving circuit for the source driver of QVGA-scale TFT-LCD driver IC to reduce the area of the source driver. In the mixed driving circuit, graphic data pass or go through the mixed channel driver whether RGB data are the same or not. The mixed driving circuit has been designed in transistor level using the 0.35um CMOS technology and has been verified using Hspice.
