Abstract
A tactile feedback apparatus includes a tactile feedback substrate and a controller. The tactile feedback substrate includes a base substrate, a first electrode layer, a piezoelectric layer, and a second electrode layer that are laminated sequentially. A plurality of electrode pairs arranged sequentially along a row direction are formed in a portion where the first electrode layer and the second electrode layer overlap with each other. The controller is configured to be capable of determining one driving mode from a plurality of driving modes as a target driving mode. In any of the driving modes, the electrode pairs are combined to form a plurality of driving units adjoined in sequence along the row direction. The number of the electrode pairs in each driving unit is different in different driving modes. The controller is further configured to drive one or more of the driving units of the target driving mode.
