Abstract:
A display device and method of sensing an input point using magnetic fluid, the display device including: a touch panel part to receive a user input through a touch at an input point and to calculate a coordinate value of the input point; an electromagnet arrangement part comprising a plurality of electromagnets to generate a magnetic force on one or more electromagnets in a portion corresponding to the coordinate value; and a magnetic fluid part to obtain magnetism at the portion corresponding to the coordinate vale and to project in accordance with the generated magnetic force.
