Tactile input/output device and driving method thereof

A method for driving a tactile input/output device, comprising:

• providing at least one input end comprising a plurality of input cells arranged at regular intervals;
• providing at least one output end comprising a plurality of output cells arranged at regular intervals;
• and
• providing a controller for controlling the at least one input end and the at least one output end,
• wherein the at least one input end and the at least one output end are installed to form one array, and
• wherein the input cell and the output cell do not overlap from each other.

A method for detecting an input signal of a tactile input/output device, comprising:

• providing at least one input end comprising a plurality of input cells arranged at regular intervals;
• providing at least one output end comprising a plurality of output cells arranged at regular intervals;
• and
• providing a controller for controlling the input end and the output end,
• wherein the at least one input end uses a plurality of piezoelectric materials arranged in a column as input cells, electrically connects the piezoelectric materials with a variable resistor, reads a variation of the variable resistor depending on a voltage difference of the piezoelectric material that varies depending on an applied pressure, and detects an input signal of various types.
