DISPLAY DEVICE AND CONTROL METHOD THEREOF
First Claim
1. A display device comprising:
- a display panel;
a sensing electrode that is disposed in a matrix pattern and outputs a sensing signal upon receiving an external stimulus;
a calculator that divides the display panel into a plurality of detection regions based on a coordinate of a first stimuli group outputting a sensing signal upon receiving a first stimulus; and
a position determiner that determines a coordinate of a second stimuli group outputting a sensing signal upon receiving a second stimulus and designates the coordinate as a stimulus position if the second stimulus is generated from a selection detection region within predetermined detection time after the first stimulus.

Abstract
A display device including a display panel, a sensing electrode that is disposed in a matrix pattern and outputs a sensing signal with respect to an external stimulus, a calculator that divides the display panel into a plurality of detection regions based on a coordinate of a first stimuli group outputting a sensing signal with respect to a first stimulus, and a position determiner is presented. The position determiner determines a coordinate of a second stimuli group outputting a sensing signal with respect to a second stimulus and designates the coordinate as a stimulus position if the second stimulus is generated from a selection detection region within predetermined detection time after the first stimulus.

15. A control method of a display device that has a display panel including a sensing electrode outputting a sensing signal with respect to an external stimulus, the control method comprising:
-
calculating a coordinate of a first stimuli group outputting a sensing signal with respect to a first stimulus; dividing the display panel into a plurality of detection regions based on the coordinate of the first stimuli group; and calculating a coordinate of a second stimuli group outputting a sensing signal with respect to a second stimulus and determining the coordinate of the second stimuli group, as a stimulus position, if the second stimulus is generated from a selection detection region selected from a plurality of detection regions within predetermined detection time after the first stimulus. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
