This paper presents a simple pixel structure that uses the voltage-programmed method to compensate for the electrical characteristic variations in low-temperature polycrystalline-silicon thin-film transistors and the current-resistance (\(I\)–\(R\)) voltage drop in the power line for active-matrix organic light-emitting diode displays. Based on the experimental results, the functionality of the pixel circuit can be operated correctly during each operation phase. Moreover, the pixel current exhibits high uniformity against the threshold voltage and mobility variations in the driving TFT.
