This work proposes a pixel circuit integrating a leakage current compensating mechanism. The pixel circuit suppresses the fluctuations of the driving current and eliminates the voltage variation at the gate node of the driving TFT by providing a compensation current. Therefore, the proposed pixel circuit is promising for smartwatch displays.
