Abstract
A display device can include a bendable display panel configured to display an image, and a piezoelectric element array film overlapping the display panel. The piezoelectric element array film can include piezoelectric power generation elements arranged in a matrix structure, and is configured to detect a capacitance change amount generated in the piezoelectric power generation elements according to bending of the display panel. The display device can further include a read-out circuit configured to receive and process a bending detection signal including the capacitance change amount generated in the piezoelectric power generation elements, and a read-out processor configured to detect whether bending of the display panel occurs and a position where the bending occurs, based on the bending detection signal.
