Abstract
The disclosure is related to a scan driving circuit for an oxide semiconductor thin film transistor and the NOR gate logic operation circuit thereof. The NOR gate logic operation circuit includes a first invertor and a second invertor applied in the pull down holding circuit of the GOA circuit, and a plurality of transistors. The combination of the NTFT and the invertor displaces the original function of the PMOS element to realize a characteristic similar to an original COMS NOR operation circuit, thereby solving a design problem of the logic operation circuit using a IGZO TFT single element, such that a larger scale digital integrated circuit is further suitably integrated into the liquid crystal display.
