A novel row‐division (RD) driving scheme together with a new AMOLED pixel circuit are proposed. The RD method can effectively increases the OLED emission time compared with the simultaneous emission method while retaining the prevalent simple pixel structure. In addition, the proposed pixel circuit, can not only effectively compensate for the threshold‐voltage shift of the driving TFT and OLED, but also make OLED bias under negative stress in the non‐emitting period to achieve an extended life expectancy.
