Abstract
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.
