P‐6.14: Improvement of Image Sticking Performance in AMOLED Display by Extending Scan Pulse Width via a Novel Driving Circuit

In this study, a novel driving circuit which could extend scan pulse width was proposed and integrated into AMOLED panel. Each scan circuit in gate‐in‐panel region contains four groups of clock signals, while the pixel circuit in active area incorporates dual data line design, in combination with a 1:4 demux circuit in the down border. The measured just noticeable difference values of short‐term and medium‐term image sticking were decreased by more than 25% in LTPS AMOLED modules. This work offers a feasible and effective method to improve the image quality in future flexible AMOLED displays.
