经过十年的深入研究，AMOLED显示器仍然面临着两大挑战。它们的产量较低，特别是对于大型面板而言，并且由于图像残留而导致使用寿命较短。低良率问题是由模拟驱动方案引起的，图像残留问题是由于 OLED 的主动发光特性造成的。通过数字驱动方案，AMOLED的良率可以提升至LCD的水平。另一方面，图像残留问题变得更加严重。它是由 OLED I-V 漂移及其效率损失引起的。本文提出了一种基于老化模型的方法，该方法可以补偿老化 OLED 像素效率的降低。可以延迟图像残留现象，并且可以显着延长 AMOLED 显示器的使用寿命。它可以促进 AMOLED 在电视和汽车显示器中的渗透，实现 AMOLED 的高图像质量和更长的使用寿命。
AMOLED displays are still facing the two major challenges after one decade of intensive researches. They are low yield particularly for large panels and modest lifetime due to image sticking. The low yield issue is caused by the analog driving scheme and the image sticking issue is due to the active emitting nature of OLED. With digital driving scheme, the yield of AMOLEDs can be lifted to the level of LCDs. On the other hand, the image sticking issue is getting even severer. It is caused by both, OLED I–V drift and its efficiency loss. In this paper, a method based on aging model is shown which compensates the reduced efficiency of aged OLED pixels. Image sticking artifacts can be deferred and the lifetime of an AMOLED display can significantly be extended. It may ease the penetration of AMOLEDs in TVs and automotive displays performing the high image quality of AMOLEDs with even longer lifetime.
