A display device includes: a plurality of pixels to receive data voltages based on converted grayscales; and a grayscale converter to: calculate first compensation offsets based on positions of the pixels and input grayscales for the pixels; convert the first compensation offsets into second compensation offsets according to a maximum luminance weight based on an input maximum luminance; and calculate the converted grayscales by applying the second compensation offsets to the input grayscales.

Display device and driving method thereof

An image correcting unit including: a data converting unit which receives image data, and generates display data by converting respective grayscale values which are included in the image data to high pixel data and low pixel data; and a white pixel detecting unit which detects image data lines which include not less than a first number of white grayscale values from the image data, and outputs a conversion signal when not less than a second number of the detected image data lines are successively arranged, wherein upon receiving the conversion signal from the white pixel detecting unit, the data converting unit converts the white grayscale values which are included in the successively arranged image data lines to first high pixel data and first low pixel data, wherein the first high pixel data and the first low pixel data have a different value from each other.
