This paper presents a mini-LED driving circuit with low power consumption. To reduce the voltage across current path, the threshold voltage variation of driving TFT is compensated by matching method. Simulations show the proposed circuit has 15.79% lower power consumption than compared circuit with two TFTs on driving current paths.
