A novel source follower circuit employing low temperature polycrystalline silicon (LTPS) thin film transistors (TFT) is proposed as an analog buffer for integrated data driver circuit. Instead of capacitive bootstrapping for self-compensation of the characteristic of TFTs, a new compensation method is applied so that the error programming of gate voltage of driving TFT can be effectively eliminated. The feasibility of proposed circuit is exhibited through the simulation results.
