Abstract
The present embodiments provide a display device including a display panel; an actuator configured to generate a predetermined vibration that is applied to the display panel; and a force sensor configured to sense force applied onto the display panel, the force sensor disposed on the display panel at a nodal point of the display panel that minimizes a portion of the sensed force resulting from the predetermined vibration generated by the actuator, and a method for manufacturing the same.
Claims20
A display device comprising:
- a display panel;
- an actuator configured to generate a predetermined vibration that is applied to the display panel;
- and
- a force sensor configured to sense force applied onto the display panel, the force sensor disposed on the display panel at a nodal point of the display panel that minimizes a portion of the sensed force resulting from the predetermined vibration generated by the actuator.
A method of manufacturing a display device, the method comprising:
- selecting a mode and a frequency;
- transferring a vibration corresponding to the selected mode and frequency to a display panel;
- identifying positions of a plurality of nodal points in the display panel, the plurality of nodal points having minimal vibration relative to other points of the display panel responsive to the transferred vibration;
- and
- disposing a plurality of force sensors at the plurality of nodal points.
The method of claim 14, wherein the experimental method includes impact hammer nodal testing comprising:
- applying an impact directly to the display panel using an impact hammer to generate the vibration.
