Abstract: A display apparatus includes a gamma controller configured to determine whether the target pixel unit is driven in both time division method and space division method based on a plurality of comparison values and a reference condition, and an output controller configured to generate normal gamma-data of the target pixel unit using a normal gamma curve if the plurality of comparison values satisfy the reference condition and to generate high gamma-data and low gamma-data of the target pixel unit using a high gamma curve and a low gamma curve in both time division method and space division method if the plurality of comparison values do not satisfy the reference condition.

Abstract: A vision inspection apparatus includes a tri-stimulus measuring part configured to measure gray tri-stimulus values of a sample grayscale and color tri-stimulus values of a full-grayscale, a color tri-stimulus generating part configured to generate color tri-stimulus values of the sample grayscale using the gray tri-stimulus values of the sample grayscale and the color tri-stimulus values of the full-grayscale, and a color correction value generating part configured to generate color grayscale correction value using the gray tri-stimulus values of the sample grayscale and the color tri-stimulus values of the sample grayscale.

Abstract: A method of displaying an image on a display panel which comprises a plurality of pixels arranged as a matrix type includes measuring a tristimulus value of X, Y and Z values of a displayed image to generate a target curve, generating a corrected grayscale data of a red pixel, a green pixel and a blue pixel using X, Y and Z values of the target curve and converting the corrected grayscale data to a data voltage to provide a data line of the display panel with the data voltage.
