Haptic actuating touch screen

摘要

Provided is a touch screen for generating a haptic sense that may minimize a structure added for haptic generation by simultaneously employing a single electrode layer that constitutes an existing touch panel as an electrode layer for transferring the haptic sense. A touch screen for generating a haptic sense according to an exemplary embodiment of the present disclosure includes a touch panel including at least one substrate, each formed with at least one electrode, and an additional electrode to generate the haptic sense on a portion touched on the touch panel using an electrostatic force that occurs between the additional electrode and a predetermined electrode among the at least one electrode.

主权项

1. A touch screen for generating a haptic sense, the touch screen comprising:
a first substrate; a second substrate; a first electrode disposed on a bottom surface of the first substrate; a second electrode disposed on a top surface of the second substrate; and a third electrode disposed below the second substrate, wherein, when the portion of the first substrate is touched and the first electrode contacts the second electrode, the second substrate is bent by an electrostatic force originating between the second electrode and the third electrode.
