摘要： A gate driver on array (GOA) circuit includes a plurality of GOA units, wherein the GOA units are cascaded. The cascaded GOA units includes an Nth-stage GOA unit including a pull-up control module, a cascade module, a pull-down holding module, a pull-down control module, and a signal output module. A structure of an inverter module in the pull-down holding module is improved. Advantageous effects are as follows. The inverter module in the pull-down holding module is optimized. Difference in a voltage-ampere characteristic between each of transistors after long-term operation of the inverter module is effectively reduced, thereby increasing operating time of the inverter module.

摘要： A threshold voltage detecting method is disclosed in the present application. In the threshold voltage detecting method provided in the present application, a path between a driving transistor and a detecting circuit is shut down during detecting, so that a current flowing through the driving transistor in a detecting stage only needs to charge a storage capacitor, but does not need to charge a parasitic capacitor on the detecting circuit, thereby shortening a threshold voltage detecting time of the driving transistor, and further improving threshold voltage detecting efficiency of the driving transistor.

摘要： A gate driving unit includes an input module, a first output module, a second output module, a feedback module, and an output-controlling module. The input module outputs a previous level-transferring signal into a first node. The first output module outputs a present level-transferring signal. The second output module outputs a scan signal. The feedback module outputs a present-level feedback signal. The output-controlling module pulls up potential of the scan signal to a first direct-current high voltage and pulls up potential of the present level-transferring signal to a second direct-current high voltage.
