摘要

New simple source follower circuits using low-temperature polycrystalline silicon thin-film transistors (LTPS-TFTs) as analog buffers for the integrated data driver circuit of active-matrix liquid crystal displays and active-matrix light emitting diodes are discussed. In addition to the threshold voltage difference of driving TFTs, the unsaturated of output voltage arisen from the significant subthreshold current will also result in the difficulty of the buffer circuit design. The proposed circuit is capable of minimizing the variation from both the signal timing and the device characteristics.
