This work proposes a pixel circuit with a compensating mechanism of leakage current to mitigate voltage fluctuation at the gate node of the driving TFT. The threshold voltage variation of LTPS TFTs is compensated to generate uniform currents. Therefore, the proposed pixel circuit is suitable for use in low-frame-rate displays.
