Touch input device, manufacturing method thereof, and touch detecting method

摘要

A touch input device including a carrying board, a plurality of first electrode pads, and a plurality of conductive lines is provided. The carrying board includes a plurality of cantilever portions and a plurality of connecting portions. The connecting portions are respectively connected to the cantilever portions. The first electrode pads are respectively disposed on the cantilever portions and configured to sense capacitance variation due to an object approaching or touching the carrying board. The conductive lines extend on the connecting portions and are respectively connected to the first electrode pads. A manufacturing method of a touch input device and a touch sensing method are also provided.

1. A touch input device, comprising:
a canying board having a reference plane, the carrying board defining an x-coordinate direction and a y-coordinate direction both parallel to the reference plane and perpendicular to each other, the carrying board comprising:
a plurality of cantilever portions; anda plurality of connecting portions respectively connecting the cantilever portions, so that each of the cantilever portions independently sags a distance in a z-coordinate direction relative to the reference plane when pressed by an object, wherein the z-coordinate direction is perpendicular to the x-coordinate direction and the y-coordinate direction; a plurality of first electrode pads respectively disposed on the cantilever portions, configured to sense a capacitance variation due to the object approaching or touching the carrying board in order to determine an x-coordinate value and a y-coordinate value of the object relative to the reference plane; and a plurality of conductive lines extending on the connecting portions and respectively connected to the first electrode pads.
