1. A method for providing a haptic feedback by a display device including a first vibration device, a second vibration device, the method comprising:
sensing a multi-touch input;
outputting a first operation information which is to be executed by a user's first touch input and receiving a first vibration data corresponding to the first operation information, wherein the user's first touch input corresponds to two simultaneous touch events;
outputting a second operation information which is to be executed by a user's second touch input and receiving a second vibration data corresponding to the second operation information, wherein the user's second touch input corresponds to three simultaneous touch events;
generating a 1A driving voltage and a 2A driving voltage according to the first vibration data and generating a 1B driving voltage and 2B driving voltage according to the second vibration data;
vibrating the first vibration device according to the 1A driving voltage and the 2A driving voltage to provide a first haptic feedback; and
vibrating the second vibration device according to the 1B driving voltage and the 2B driving voltage to provide a second haptic feedback,
wherein the first haptic feedback has a lower frequency and amplitude than the second haptic feedback and wherein the first haptic feedback has a longer duration than the second haptic feedback.
