Abstract: A method of driving a light source includes converting a reference luminance value of the light source to a first just noticeable difference (JND) value. The JND value represents a minimum noticeable difference between two stimuli. A target luminance value lower than the reference luminance value is determined using the first JND value. A first driving signal applied to the light source is generated using the target luminance value so that a user may not notice a luminance change when a luminance value of a light source is decreased in order to decrease power consumption of a display apparatus.
