Pressure feedback device, and touch display device and working method thereof

The invention discloses a pressure feedback device, and a touch display device and a working method thereof. The touch display device comprises a display panel, a pressure sensing device and a touch feedback device, wherein the pressure sensing device and the touch feedback device are positioned on the display panel; the pressure sensing device is used for sensing a pressure signal when a touch occurs, such that a processor generates a feedback signal according to the pressure signal; and the touch feedback device is used for performing corresponding feedback operation according to the feedback signal. According to the touch display device provided by the invention, the pressure sensing device senses the pressure signal when the touch occurs, such that the processor generates the feedback signal according to the pressure signal; the touch feedback device performs the corresponding feedback operation according to the feedback signal; therefore, on the basis of a touch function, the operation experience of users is improved; and thus, the problem that the users feel monotonous and boring can be avoided.
