  • Method for providing haptic feedback
    Patent number: 11726573
    Abstract: A method for providing haptic feedback includes sensing a user's input through a display panel, determining haptic feedback corresponding to the input, and controlling a voltage applied to each of the plurality of actuators to provide the determined haptic feedback to a location where the input is sensed, wherein the controlling of the voltage applied to each of the plurality of actuators includes adjusting the voltage applied to each of the plurality of actuators to reduce the magnitude of radiation noise of the panel due to excitation of the plurality of actuators and to uniformize the magnitude of the noise for each location of the panel.

  • PIEZO ACTUATOR MODULE FOR BROADBAND-FREQUENCY HAPTIC FEEDBACK
    Publication number: 20230158545
    Abstract: A piezo actuator module capable of haptic feedback in a wide frequency range comprises an actuator layer including a piezo actuator having one surface coupled to an object to be excited and vibrating by an electric signal and an inertial mass layer having a certain mass and coupled to the other surface of the actuator layer. The inertial mass layer supports the other surface of the actuator layer when the piezo actuator vibrates.
