Dual gate TFT has been widely used for AMOLED pixel compensation circuit to reduce leakage current and to have good reliability. The study shows that single gate TFT has better off-state performance than dual gate TFT. Therefore, new pixel compensation circuit designed with only single gate TFTs is suggested.
