PURPOSE: A touch screen and an operating method of the same are provided to locally provide pressure, a repulsive force, and vibrations when a user contacts the touch screen in a contract feedback unit using a magnetic force. CONSTITUTION: A sensing unit(150) senses the access or contact of an object. A control unit receives a signal from the sensing unit. The control unit outputs a feedback signal. A tactile feedback unit receives the feedback signal of the control unit. The tactile feedback unit applies tactile feedback using a magnetic force in a contacted position. A magnetic force of a magnetic dipole is used in the tactile feedback. The tactile feedback comprises a first magnetic unit(142) and a second magnetic unit(144). |
