A gate driver on array (GOA) circuitry unit comprises a scan part and an inverter. The output terminal of the scan part is connected to the inverter, and an emission signal is generated after the scan signal output by the scan part passes through the inverter. Because the inverter is used for generating the emission signal, extra thin film transistors (TFT's) and capacitors are not necessary for generating the emission signal, number of TFT and capacitor is reduced, and narrow border design is benefit therefrom. A GOA circuit using the GOA circuitry unit, a display and a driving method for the GOA circuitry unit are also provided.
