    摘要: A touch sensing apparatus includes a light source generating a light. The light travels though a light distribution part. A light guide part guides the light to the light distribution part. A light sensing part outputs an output signal corresponding to an intensity of the light incident through the light guide part and the light distribution part when a touch occurs. A light reflection part reflects the light provided to the light distribution part, and a coordinate generating part calculates a coordinate value of the touch using the output signal from the light sensing part.

    摘要: Provided is a touch screen. The touch screen includes a touch panel including a first substrate and a second substrate that face each other. The first resistor line part is bent several times, has a first end receiving a first voltage, and has a second end receiving a second voltage having a potential lower than the first voltage. Also, the touch screen includes a touch detection unit that determine whether a touch event occurs, a single/multi touch determination unit that determines whether the touch event is single touch or multi-touch, and a coordinate information calculating unit that calculates coordinate information of a touched point. Therefore, the touch screen may calculate coordinate information of multi-touched points.
