Abstract
The present disclosure provides a tactile feedback device, including: a deformable structure, a driver coupled to the deformable structure, and a controller coupled to the driver. The deformable structure is configured to include a plurality of deformable units placed on a display panel, each of the plurality of deformable units being capable of deforming along a direction at an angle to a plane the plurality of deformable units is placed on. The controller is configured to generate and send a control signal to the driver, the control signal being based on a touch location of a touch motion. The driver is configured to drive deformable units corresponding to the touch location to deform based on the control signal.
