Tactile device

A tactile device comprising:

• a substrate provided with a first surface;
• an organic piezoelectric film arranged on the first surface side of the substrate, the organic piezoelectric film having a piezoelectric property;
• a plurality of electrodes arranged on the first surface of the substrate;
• and
• a plurality of drive circuits arranged between the substrate and the organic piezoelectric film, each of the drive circuits being configured to apply a drive voltage to the organic piezoelectric film during a piezoelectric driving period for driving the organic piezoelectric film,
• wherein, in a plan view, the organic piezoelectric film is divided into a plurality of cells,
• wherein the plurality of electrodes includes:
• a common electrode arranged across the plurality of cells in the plan view, a reference potential being supplied to the common electrode during the piezoelectric driving period;
• and
• a plurality of driving electrodes respectively arranged in the plurality of cells in the plan view,
• wherein the plurality of drive circuits includes:
• a first drive circuit capable of supplying a first driving signal during the piezoelectric driving period;
• and
• a second drive circuit capable of supplying a second driving signal during the piezoelectric driving period, the second driving signal being different from the first driving signal,
• wherein the plurality of driving electrodes includes:
• a first driving electrode connected to the first drive circuit;
• and
• a second driving electrode electrically separated from the first driving electrode and connected to the second drive circuit, and
• wherein the first driving electrode and the second driving electrode are arranged in each of the plurality of cells.
