A depletion-mode indium-gallium-zinc-oxide thin-film-transistor (IGZO-TFT) gate driver on array (GOA) integrated circuit has been proposed. IGZO-TFTs are turned off completely due to the introduction of series-connected two-transistor structure and dual low-voltage-level power signal. Finally, the GOA circuit was placed in a 31-inch AMOLED display to testify the function.
