Abstract
A display device including a display panel including data lines, gate lines, and pixels applied with pixel driving voltages; a data driver configured to supply pixel data to the data lines; a power supply configured to apply the pixel driving voltage to the pixels; and a compensation circuit configured to generate a pixel driving voltage drop amount using a pixel driving voltage applied from the power supply and a pixel driving voltage fed back from a central portion of the display panel, amplify the generated pixel driving voltage drop amount using a predetermined gain value, and generate a compensation voltage value for compensating a gamma reference voltage for a corresponding pixel using the amplified pixel driving voltage drop amount.
