Abstract
A GOA driving circuit, a TFT display panel and a display device are disclosed. The GOA driving circuit includes: an input module configured for outputting first control signals in accordance with the received display scanning signals and the touch scanning signals; an output module configured for outputting the first output control signals in accordance with the first control signals and the first clock signals; a pull-down module configured for outputting pull-down signals in accordance with the first control signals, the second control signals and the low level signals; and a pull-down maintaining module configure for outputting the second output control signals in accordance with the pull-down signals, the high level signals, and the first clock signals. The DC source is adopted to charge/discharge Qn to keep Qn at a reasonable level, and the transfer capability is enhanced. In addition, the forward scanning and the backward scanning may be implemented.
