A GOA (Gate On Array) circuit applied to a liquid crystal display device is disclosed. The liquid crystal display device has a plurality of scan lines. The GOA circuit has a plurality of cascaded GOA units. An (N)th level GOA unit is controlled to charge an (N)th level scanning line accordingly. The (N)th level GOA unit includes a signal transfer circuit, an inverting amplifier circuit, a signal reset circuit, and an inverting logistic circuit. Processing a first screen scanning procedure, the GOA circuit will forward scan from the 1st level GOA unit to the (N)th level GOA unit, while the GOA circuit receives a touch signal, the GOA circuit enters into a touch point scanning procedure, then entering into a second screen scanning procedure. This improves the format of touch scanning and increases the report rate of the touch panel to improve the sensitivity of the touch panel.
