Abstract

This letter presents a novel pixel circuit that uses low-temperature polycrystalline-silicon thin-film transistors (LTPS-TFTs) composed of one driving and four switching TFTs for active-matrix organic light-emitting diodes (AMOLEDs) with a voltage-source method. The proposed circuit effectively enables threshold-voltage-shift correction of the drive TFT and compensates for degradation of the OLED using a feedback structure.
