P‐231: Late‐News Poster: An AMOLED LTPS Pixel Circuit Compensating for Threshold Voltage Variations, OLED Degradation, and IR Drop

In this paper, we proposed active‐matrix organic light‐emitting diode (AMOLED) low temperature poly‐crystalline silicon (LTPS) pixel circuit compensating for variations in threshold voltage (V TH ), organic light‐emitting diode (OLED) degradation, and IR drop. The proposed circuit is composed of six thin film transistors (TFTs) and two capacitors. From the simulation results, the maximum OLED current error rates are 6.76%, 12%, and 5.89%, when the V TH shift is ‒1 V, the OLED stress time is 40,000 s, and the ELVDD reduction is 10%, respectively.
