Display device |
| abstract |
A display device according to an embodiment of the present invention includes: an insulation layer having an insulation surface; and a touch sensor provided on an upper surface of the insulation surface; the touch sensor includes a plurality of first electrodes and a plurality of second electrodes provided on the upper surface of the insulation surface forming first electrostatic capacitance, a piezoelectric layer provided on upper surfaces of the plurality of first electrodes and the plurality of second electrodes and charged according to applying a pressing force, a pulse generator applying a pulse voltage to the first electrodes, and a determination circuit detecting a change in the first electrostatic capacitance from a change in a first measurement value caused by the application of the pulse voltage and detecting strength of the pressing force from a change in a second measurement value not caused by the application of the pulse voltage. |
