New simple analog buffers employing LTPS‐TFTs are proposed for the integrated data driver circuits of AMLCD and AMOLED. The proposed analog buffers do not use capacitors to store the threshold voltage of a poly‐Si TFT, so that high speed driving is possible in the large size display panel. The simulation results exhibit that the variation of poly‐Si TFT characteristics is successfully compensated in the proposed analog buffers.
