In this study, an architecture for 262K-color TFT-LCD source driver. In this paper proposed the chip consumes smaller area and static current which is suitable for QVGA resolutions. In the conventional structures, all of them need large number of OPAMP buffers to drive the pixels, Therefore, highly resistive R-DACs are needed to generate gamma voltages to reduce the static current. In this study, our design only used two OPAMPs and low resistance RDACs without increasing the quiescent current. Thus, it was experted that chip would be more in consuming lower static power for longer battery lifetime. The source driver were implemented by the 3.3 V $0.35\;{\mu}m$ CMOS technology provided by TSMC. The area of the core OPAMP circuit was about $110\;{\mu}m\;{\times}\;150\;{\mu}m$ and that of the source driver was $880\;{\mu}m\;{\times}\;430\;{\mu}m$. As compared to the conventional structure, approximately 64.48 % in area was achieved.
