Abstract
A display apparatus having a mura compensation function includes a mura memory in which compensation data corresponding to coefficient values of a mura compensation equation is stored; and a mura compensation circuit configured to perform mura compensations on display data by using the mura compensation equation to which the compensation data has been applied, wherein the coefficient values are set so that the mura compensation equation has been fit to have a curve that satisfies known difference values of selected gray levels, a first estimation difference value of a first estimation gray level higher than the selected gray levels, and a second estimation difference value of a second estimation gray level lower than the selected gray levels, and wherein the compensation data comprises the coefficient values of the mura compensation equation in which all of the known difference values of the selected gray levels, the first estimation difference value, and the second estimation difference value have a difference within a preset error range.
