Abstract: The present invention relates to a haptic feedback screen using a piezoelectric polymer. The present invention provides a haptic feedback screen using a piezoelectric polymer, which comprises: a piezoelectric polymer layer made of a transparent piezoelectric polymer material; an upper electrode and a lower electrode disposed on an upper surface of and under a lower surface of the piezoelectric polymer layer, respectively, the upper electrode and the lower electrode being made of a transparent material; a transparent cover disposed on the upper electrode; and a transparent substrate disposed under the lower electrode, wherein the piezoelectric polymer layer generates vibration in a touch area by a power applied between the upper electrode and the lower electrode when a touch occurs on the transparent cover. The present invention can implement an overall or partial haptic feedback function by applying a transparent piezoelectric polymer material to a touch screen.
