MONOLITHIC HAPTIC TYPE TOUCH SCREEN, MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE INCLUDING THE SAME

摘要

A monolithic haptic-type touch screen capable of performing both touch recognition and haptic feedback are provided. The monolithic haptic-type touch screen includes an insulating film formed by doping ferroelectric material in an electroactive polymer (EAP), an upper electrode formed on an upper surface of the insulating film, and a lower electrode formed on a lower surface of the insulating film and corresponding to the upper electrode.
