Active matrix organic light emitting diode pixel circuit capable of automatically compensating current

The active matrix organic LED pixel circuit capable of automatically compensating current has one active load configured in the drive current conveying path of organic LED pixel. When the voltage across the organic LED raises with operation time, the drive current flowing through the organic LED may be compensated automatically to improve homogeneity of the displayed picture. 一种可自动补偿电流的主动矩阵有机发光二极管像素电路，就是在有机发光二极管像素的驱动电流传送路径上配置一个主动负载，在有机发光二极管的跨压随着操作时间上升时，可自动补偿流经有机发光二极管的驱动电流，以改善显示画面的均匀度。
