The performance of flexible OLED display has been improved by using driver thin film transistors (DTFTs) with BSM, including lifetime and image sticking, which is mainly due to improvement of DTFT reliability. TCAD simulation shows that BSM can shield the charge from organic substrate, and enhance device stability significantly, thereby improves the flexible OLED display quality.
