Abstract
A force touch device, a force touch feedback method and a touch display device are provided. The force touch device includes a first region and a second region, and further includes: a force detecting electrode in the first region and the second region; a sensing electrode in the first region; an auxiliary electrode in the second region, and the auxillary electrode and the sensing electrode are on a same side of the force detecting electrode. The sensing electrode and the force detecting electrode are disposed oppositely and insulated from each other to form a first force sensor, the auxiliary electrode and the force detecting electrode are disposed oppositely and insulated from each other to form a second force sensor, and a distance of the auxiliary electrode from the force detecting electrode is greater than a distance of the sensing electrode from the force detecting electrode.
