We propose a novel dual-output scan driver circuit employing low-temperature polycrystalline silicon and oxide (LTPO) thin-film transistors (TFTs). It was confirmed that the output is stably generated at a threshold voltage of -5 V to +8 V. The proposed circuit has a very simple structure of 7T1C and generates two outputs in one circuit, so it is suitable for narrow-bezel mobile displays.
