Abstract
A touch sensing device includes: a substrate; a first sensor disposed on the substrate; a second sensor disposed on the substrate; and a sensing circuit electrically connected to the first sensor and the second sensor. The sensing circuit is configured to compare signals sensed by the first sensor and the second sensor in accordance with an applied touch input and determine whether the applied touch input is normal.
Claims18
A touch sensing device, comprising:
- a substrate disposed in a housing;
- a first sensor disposed on the substrate, in a normal touch sensing portion;
- a second sensor disposed on the substrate, in a malfunction touch sensing portion;
- and
- a sensing circuit electrically connected to the first sensor and the second sensor,
- wherein the sensing circuit is configured to compare signals sensed by the first sensor and the second sensor in accordance with an applied touch input and determine whether the applied touch input is normal, and
- wherein the first and second sensors are disposed adjacent to each other in a direction from a front display disposed on one side of the housing to a rear cover disposed on another side of the housing opposite the one side.
