1. A display device comprising:
- a first touch sensor;
a second touch sensor disposed in proximity to the first touch sensor;
a shade located on the second touch sensor wherein the shade controls intensity of incident light to the second touch sensor so that the second touch sensor receives a different intensity than the first touch sensor; and
a reader which receives a first signal and a second signal from the first touch sensor and the second touch sensor, respectively, and which analyzes the first signal and the second signal.
