Abstract
A display device includes a display panel configured to display an image; a restoring unit configured to receive a data packet and sequentially restoring display data corresponding to red, green and blue colors of sub-pixels from the data packet; a mura compensation circuit configured to receive the restored display data, generate adjusted compensation values and compensate for mura on the display data corresponding to the colors of the sub-pixels using the adjusted compensation values corresponding to location information of the sub-pixels having the mura; and an output circuit configured to receive the mura compensated display data and output a source signal to the display panel in accordance with the data packet, wherein the adjusted compensation values are generated by applying a first gain that is proportionally increased from 0% to 100% at a first region between a lowest gray scale and a first gray scale, a second gain that is 100% at a second region between the first gray scale and a second gray scale, and a third gain that is proportionally decreased from 100% to 0% at a third region between the second gray scale and a highest gray scale.
