High resolution and low power are very significant requirements such as notebook, mobile phones, PDAs, PC, TV screens and other consumer electronics. The source driver must drive one column source of TFT which output load is proportioned to the panel size, so the source driver must have large driving capability. However, the traditional source driver which driving capability has to be increased to satisfy the requirement of high resolution. One of the most common ways is increased the the output buffer width for enhancing the driving capability. In this way, although it increases the driving capability, it consumes much more power, and costs much more layout area. The thesis focures on the source driver of the TFT LCD flat panel displays, and finds out a solution that uses over-driving method to reduce the settling time. The thesis uses row inversion to drive the TFT LCD. Modulating common voltage driving method and the low power Class-B Rail-to-Rail output buffer are used to economize the power consumption. The source driver is suitable for XGA 1024×768 resolutions, 60 frames per second. The design of the over-driving source driver has been implemented with TSMC 0.35um CMOS 2P4M 5V process. When the output loads is 10 sets of 1kΩ resistance and the 15pF capacitance, the settling time is 4.7237 μs and the average power is 17.518mW, and DNL、INL is less then 1/2 LSB. none 許明華 2005 學位論文 ; thesis 99 zh-TW |

碩士 === 國立雲林科技大學 === 電子與資訊工程研究所 === 93 === With the wide applications of the liquid crystal flat panel display, the flat panel displays are now everywhere in our daily life. High resolution and low power are very significant requirements such as notebook, mobile phones, PDAs, PC, TV screens and other consumer electronics. The source driver must drive one column source of TFT which output load is proportioned to the panel size, so the source driver must have large driving capability. However, the traditional source driver which driving capability has to be increased to satisfy the requirement of high resolution. One of the most common ways is increased the the output buffer width for enhancing the driving capability. In this way, although it increases the driving capability, it consumes much more power, and costs much more layout area.
The thesis focures on the source driver of the TFT LCD flat panel displays, and finds out a solution that uses over-driving method to reduce the settling time.
