TOUCH PANEL AND ELECTRONIC DEVICE INCLUDING THE SAME
First Claim
1. A touch panel comprising:
- a first substrate;
a second substrate that is spaced apart from the first substrate by a gap, the second substrate comprising a touch surface;
an electro-rheological fluid that is filled in a gap between the first substrate and the second substrate;
a sensor that senses an input on the touch surface and determines an input location at which the input occurs; and
a controller that varies a viscosity of the electro-rheological fluid in a location corresponding to a peripheral region of the input location.

Abstract
A touch panel and an electronic device including the same are provided. The touch panel includes a first substrate, a second substrate, an electro-rheological fluid, a sensor, and a controller. The second substrate is spaced apart from the first substrate by a gap and includes a touch surface. The electro-rheological fluid is filled in a gap between the first substrate and the second substrate. The sensor senses an input on the touch surface and determines an input location at which the input occurs, and the controller varies a viscosity of the electro-rheological fluid in a location corresponding to a peripheral region of the input location.

7. A touch panel comprising:
-
a first substrate; a second substrate that is spaced a apart from the first substrate by a gap, the second substrate comprising a touch surface; a plurality of driving electrode arrays in which driving electrodes are arranged on the first substrate and the second substrate such that the driving electrodes form driving electrode pairs, each of the driving electrode pairs including a driving electrode on the first substrate and a corresponding driving electrode on the second substrate and each of the driving electrode pairs is configured to induce an electrical field locally between the first substrate and the second substrate upon application of a driving voltage; an electro-rheological fluid that is filled in the gap between the first substrate and the second substrate, wherein a viscosity of the electro-rheological fluid is changed by an electrical field induced by the driving electrode pairs; and a controller that, when a continuous input from a user is sensed on the touch surface, applies a driving voltage pattern to driving electrode pairs in a location corresponding to at least one peripheral region of a latest input location among locations at which the continuous input is sensed. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20)
