摘要

OLED电视在使用过程中会出现OLED显示屏因驱动电路的阈值电压漂移和寿命不足而导致性能退化的问题，进而使显示屏出现残影（烧屏）现象。本文提出了采用像素补偿和电流补偿两种方案来消除或者减弱OLED显示屏的残影，通过加速老化实验的方法，验证了该两种方案能够有效消除或缓解OLED电视屏幕残影的产生，可以使显示屏出现残影的时间点延后13 340 h，将其正常使用时间延长近80%，有效提高了OLED电视屏幕使用寿命。

Abstract

During the operation of an OLED TV

the threshold voltage drift and the degradation of OLED panels will lead to the phenomenon of sticking image on the AMOLED display

especially in OLED TV. Two solution methods are presented: pixel compensation and current compensation to eliminate or reduce the sticking image on the screen of the OLED TV

and improve the lifetime of OLED TV. The accelerated aging test was used to verify that the solutions can effectively eliminate or alleviate the generation of sticking image on the screen of OLED TVs. The time of the appearance of sticking image can be delayed 13 340 h

as well as the available time of the screen was increased by nearly 80%. The lifetime of the OLED TV was effectively improved.
