Abstract: A touch pad including a touch sensor, a force sensor, a printed circuit board, and a touch controller is provided. The touch sensor includes first and second touch electrode layers, and a first substrate. The first touch electrode layer is arranged above the second touch electrode layer through the first substrate. The force sensor is arranged below the touch sensor, and includes a support structure and at least one pressure electrode layer. The support structure is a deformable structure, and is configured to deform under the action of a pressure applied by a finger when pressing the touch pad to change a pressure sensing capacitance of a finger pressing region, and output a corresponding pressure sensing signal through the at least one pressure electrode layer. The printed circuit board is arranged below the force sensor. The touch controller is mounted and fixed to the printed circuit board.
