79‐2: Large‐Area Single‐Crystal Actuator for Multifunctional Haptic Displays

Haptic interface is essential for improved user interaction with various displays by the sense of touch. However, current haptics in most displays provide limited tactile feedbacks due to their narrow operating frequencies. We present a multifunctional haptic display with a large‐area single crystal actuator which allows more diverse user experiences with a broad range of frequencies. The haptic actuator composed of the single crystal leads to high vibrational performance originated from its superior electromechanical properties. Furthermore, the automotive “Smart Surface” organic light‐emitting diode (OLED) display integrated with the actuator suggests a new direction for future interactive display applications.
