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.
Claims18
A display device comprising:
- a display panel including a center portion and an edge portion;
- an actuator configured to generate a predetermined vibration that is applied to the display panel;
- a force sensor configured to sense force applied onto the display panel, the force sensor disposed on the center portion of 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 plate supporting the force sensor, the plate disposed between the force sensor and the actuator;
- and
- a layer disposed in the center portion and disposed between the display panel and the actuator and on a same plane as the force sensor, and wherein the layer at least partially surrounds the force sensor.

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 including a center portion and an edge portion;
- 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;
- disposing a plurality of force sensors at the plurality of nodal points on a center portion of the display panel;
- attaching a plate to the plurality of force sensors, the plurality of force sensors attached to a first side of the plate;
- and
- forming a layer in the center portion and disposing between the plate and the display panel and on a same plane as the plurality of force sensors, wherein the layer at least partially surrounds the plurality of force sensors.
