DISPLAY PANEL INCLUDING PIEZOELECTRIC DEVICE AND METHOD FOR COMPENSATION PROPERTIES OF PIEZOELECTRIC DEVICE

摘要

The present invention relates to a display panel including a piezoelectric device and a method for compensating the properties of the piezoelectric device. The display panel includes a panel, and a piezoelectric device combined with the panel. The piezoelectric device may include a plurality of piezoelectric devices which are arranged in different positions of the panel, and generate vibration according to a driving signal; a driving part which supplies the driving signal to the piezoelectric devices; a plurality of acceleration sensors which detect acceleration information due to the vibration, in the different regions of the panel; and a compensation part which controls the driving signal to compensate the property deviation of the piezoelectric device, based on the acceleration information. So, uniform haptic feedback can be provided.
