recording the coordinate of the previous frame, the coordinate of the previous frame and the coordinate of the previous frame of the single finger parallel to the current coordinate of the marking point of the induction channel;
judging whether the current coordinate of the single-finger parallel induction channel scribing point is located at the position of a driving channel which is one, the same or next to the single-finger pressing fixed point or not, and if so, partially smoothing the current coordinate of the single-finger parallel induction channel scribing point;
and replacing the current coordinate of the single-finger parallel induction channel scribing point with the partially smoothed coordinate.
4. A touch display device comprising the partial-smoothness-based touch recognition device of claim 3.
