Abstract
The present disclosure is related to a display panel. The display panel may include a plurality of switch units. Each of the plurality of the switch units may include a first electrode; a second electrode; a third electrode; a fourth electrode opposite the first electrode; a piezoelectric material layer between the first electrode and the fourth electrode; a connecting electrode above the fourth electrode and electrically insulated from the fourth electrode; and a driving transistor comprising a driving gate. The driving gate may be the third electrode. An orthogonal projection of the second electrode and an orthogonal projection of the third electrode on a plane of the connecting electrode may overlap the connecting electrode respectively.
