摘要


本論文中提出了兩種給薄膜電晶體液晶顯示器應用之源極驅動器,第一種是應用在大面板的UXGA薄膜電晶體液晶顯示器上,第二種是應用在可攜式小尺寸薄膜電晶體液晶顯示器上。 第一個源極驅動器利用一組DAC Decoder提供給兩個channel使用,使DAC的decoder數目減少一半,晶片面積即可減小以降低成本。 第二個源極驅動器利用少數的緩衝器加在電阻串前,可加速穩定電阻串電壓以快速驅動面板。此架構可以驅動數百個channel,相對的功率消耗與晶片面積皆可減少。

In this thesis, two types of source drivers for TFT-LCD applications are proposed. The first one is designed for the UXGA specification which is used in a large TFT-LCD panel, and the second one is suitable for the portable small-scale TFT-LCD. For the first source driver, two channels share one DAC decoder, so that the number of DAC decoder can be reduced by half to save the chip area and costs. For the second source driver, a few buffers are added in front of the R-string, which stabilize the voltage of the R-string faster in order to drive the panel quickly. This structure can drive hundreds of channels, and relatively the power dissipation and chip area can be reduced.
