Abstract
A luminance compensation method of a display device includes a first luminance for a reference grayscale at a first operating frequency and a second luminance for the reference grayscale at a second operating frequency are measured. A first reference value is calculated based on the first luminance and the second luminance, a first duty ratio of the initialization control signal is changed into a second duty ratio depending on a comparison result of the first reference value and a threshold value After the first duty ratio is changed into the second duty ratio, a third luminance for the reference grayscale is measured, and a second reference value is calculated based on the first luminance and the third luminance. A final duty ratio corresponding to the threshold value is calculated depending on a comparison result of the second reference value and the threshold value.
