A scan signal compensating method, a scan signal compensating circuit and a display device are provided. The compensating method includes: disposing a reference TFT; obtaining a drain current of the reference TFT; acquiring a compensation voltage value according to the drain current; and performing voltage compensation to a GOA driving circuit according to the compensation voltage value. By disposing the reference TFT to acquire a drift of I-V characteristic curve of a certain TFT of the GOA driving circuit, obtaining the compensation voltage value according to a drifted drain current of the reference TFT and compensating a driving voltage of the GOA driving circuit, the problem of display image sticking or flickering caused by the drift of I-V characteristic curve of the TFT in the GOA driving circuit resulting from a long-term bias voltage can be solved consequently.
A scan signal compensating method adapted for a gate driver on array (GOA) driving circuit, wherein the compensating method comprises:
A scan signal compensating circuit electrically connected to a GOA driving circuit, wherein the compensating circuit comprises:
A display device comprising a GOA driving circuit and a scan signal compensating circuit electrically connected to the GOA driving circuit;
