Abstract:
The present invention provides a GOA circuit applied for the In Cell type touch display panel. The third transmission gate (TG3) comprising the second P-type thin film transistor (T2) and the third N-type thin film transistor (T3), the first P-type thin film transistor (T1) and the fourth N-type thin film transistor (T4) are added in the output buffer module (600), and the touch control signal (TCK) and the inverted touch control signal (XTCK) are introduced to control the working status of the output buffer module (600). Thus, in the touch scan stage, the third transmission gate (TG3) is deactivated, and the first, the fourth thin film transistors (T1, T4) are activated, and the gate scan driving signal output end (Gate(N)) is floating, and similarly jumps between high, low voltage levels along with that the touch scan driving signal jumps between high, low voltage levels.
