Abstract:
The invention provides a GOA circuit, the forward-and-reverse scan control module of the GOA circuit comprising: a first TFT and a third TFT, the first TFT having the gate connected to the gate scan drive signal of the (n−1)-th GOA unit, the source connected to the first constant voltage, and the drain connected to a first node; and the third TFT having the gate connected to the gate scan drive signal of the (n+1)-th GOA unit, the source connected to the first constant voltage, and the drain connected to the first node. With the two TFTs to control the switching of forward and reverse scanning of the GOA circuit, the present invention eliminates two control signals without increasing the numbers of TFTs and capacitors. As such, the selection for IC is increased, which enables the realization of narrow border LCD.
