S2-28: A Precise Macro Model of Low Temperature Poly-Silicon Thin Film Transistor for Active Matrix Organic Light Emitting Diode Display
A macro model of low temperature poly-silicon thin film transistor (LTPS TFT) is proposed to evaluate the performance of active matrix organic light emitting diode (AMOLED) display panel circuit with LTPS technology. In this paper, the circuit structure and the component parameters extraction of the macro model are presented. The effect of hysteresis is expressed with this macro model. The hysteresis results in threshold voltage shift of LTPS TFTs that will degrade the uniformity of AMOLEDs display. With this macro model, we can explore efficient AMOLEDs display back panel circuit with careful consideration of the effect of hysteresis.
