Beschreibung
Zusammenfassung:	An analog buffer, display device having the same and a method of driving the same are provided. The analog buffer applies an analog voltage to a load. The analog buffer includes a comparator and a transistor. The comparator is configured to compare an input voltage provided from an external device with the analog voltage applied to the load. The transistor is turned on to electrically charge the load when the analog voltage is lower than the input voltage or turned on to electrically discharge the load when the analog voltage is higher than the input voltage, and turned off when the analog voltage becomes substantially the same as the input voltage.
