In oriental medicine, there is the fundamentals to lead a stirring life, and it is an important matter that make a study of fundamentals for treatment. The su-wen(素問) mentions the fundamentals of sheng(生之本), the fundamentals of qi(氣之本), the fundamentals of feng-cang(封藏之本), the fundamentals of ba-ji(罷極之本) and the fundamentals of cang-lin(倉廩之本). They are terminologies expressing physiological functions of the five viscera - heart, lungs, kidneys, liver and spleen. The five viscera are expressed through face, fur, hair, nail and lips. And the five viscera are closely connected with blood, skin, bone, muscle and flesh. Through the changes of personal appearance, we can recognize those of their internal organs. In oriental medicine, they are called as the cang-xiang(藏象). Heart is the fundamentals of sheng(生), and it is related to spirit, blood and blood vessel. Lungs are the fundamentals of qi(氣), because they master the extensive meaning of qi(氣). Kidneys are the fundamentals of feng-cang(封藏) which means seclusion. Liver is the fundamentals of ba-ji(罷極) that have several view by concept. Spleen, stomach, large and small intestines, paunch and bladder are the fundamentals of cang-lin(倉廩), that is to say, gastrointestinal tract that ingest diet and digest it.

In this study, we used a multiple phase scheme for the clock in the dual-pull-down driver for TFT display panels. In this scheme, the turn-on time for the transistors in the dual-pull-down structure was reduced from 1/2 to 1/4 or 1/8 of the period cycle time. While keeping proper operation of the transistor size of circuit was fine tuned to achieve an optimal performance. The relation between the active time and the transistor dimensions was obtained for the optimal design.

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.
