    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.
