Abstract: A display apparatus a display panel that includes pixels arranged in rows by columns, which are connected to gate lines and data lines, a timing controller that outputs control signals and data signals, a gate driver that applies gate signals to the pixels through the gate lines, and a data driver that receives the data signals and applies data voltages corresponding to the data signals to the pixels through the data lines. The timing controller checks whether a pattern of data values corresponds to a checker pattern, in which black and white patterns are alternately repeated in a row direction and a column direction, checks whether an area of the checker pattern is equal to or greater than a predetermined area of the display panel, and compensates for the data signals in accordance with the checked result.
