A new current scaling pixel circuit using three low‐temperature polycrystalline‐silicon (LTPS) thin‐film transistors (TFTs) for Active Matrix Organic Light Emitting Diodes (AMOLEDs) is presented. The proposed circuit with simplified components can enhance the aperture ratio, accelerate the pixel programming time, as well as compensate for the variations of TFT threshold voltage.
