Plastic organic light emitting diode displays suffer from residual image, which is closely connected with the hysteresis of the driving thin-film transistor in the pixels. Therefore, in researching paper, we manufactured an OLED display comprise a polyimide substrate and an amorphous indium gallium zinc oxide thin film transistor active layer. Paper proposed a solution for reducing hysteresis through oxygen partial pressure control and evaluated it using hysteresis analysis. The results showed that hysteresis is strongly dependent on the threshold voltage is settled by the oxygen partial pressure while active layer deposition of the TFT. Moreover, hysteresis decreases with increasing temperature.
塑料有机发光二极管显示器存在残留图像问题，这与像素中驱动薄膜晶体管的滞后现象密切相关。因此，在研究论文中，我们制造了一种有机发光二极管显示器，它包括一个聚酰亚胺基板和一个非晶铟镓锌氧化物薄膜晶体管有源层。论文提出了一种通过控制氧分压来减少滞后现象的解决方案，并使用滞后分析对其进行了评估。结果表明，滞后现象强烈依赖于在薄膜晶体管有源层沉积时由氧分压确定的阈值电压。此外，滞后现象随温度升高而降低。
