A compensation method for an induced amount in a touch sensor and a touch panel thereof are provided. The compensation method uses a fake finger circuit to simulate the situations when a user touches the sensing nodes of the touch sensor with a finger, and obtains the gain coefficient of each of the sensing nodes, which are used to compensate for the induced capacitance generated by the sensing nodes as a result of being touched by an external object. In this way, the extra effects caused by the difference in basic capacitance can be eliminated by the gain coefficient.
A compensation method for an induced amount in a touch sensor performed on a touch controller, the touch sensor including a plurality of sensing lines arranged parallel to a first direction and a plurality of driving lines arranged parallel to a second direction, in which the plurality of the sensing lines intersect the plurality of driving lines to form a plurality of sensing nodes, and the touch controller is electrically connected to the plurality of sensing lines and the plurality of driving lines so as to transmit a driving signal to the plurality of driving lines and receive an induced capacitance in relation to each of the plurality of sensing nodes from the plurality of sensing lines, the compensation method for an induced amount comprising:
A touch panel, comprising:
