Abstract:
There is provided a display panel including a piezoelectric device and a method for compensating properties of a piezoelectric device. According to the an exemplary embodiment of the present disclosure, the display panel includes: a panel; and a piezoelectric device coupled with the panel, wherein the piezoelectric device includes: a plurality of piezoelectric elements disposed at different positions of the panel and each configured to generate vibrations according to a driving signal; a driver configured to supply the driving signal to the plurality of piezoelectric elements; a plurality of acceleration sensors configured to detect acceleration information of vibrations in different regions of the panel; and a compensator configured to control the driving signal to compensate for property deviations of the plurality of piezoelectric elements, based on the acceleration information.
