Abstract: The defects of an OLED-based display,mainly electrical shorts,cause pixels to stay dark,decrease the brightness of a panel,severely influence the display uniformity,and also consume a considerable amount of power.In this paper,for AM-OLEDs,a novel circuit employing p-type low-temperature poly-Si thin-film transistors is introduced to offer fault-tolerant capabilities for such defects.The results show that this circuit can save significant power and maintain the luminance of the pixel without changing the driving current.
