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.

Display apparatus and method of driving the same

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.

Display panel inspection apparatus

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.

Method of displaying an image, display apparatus performing the same, method of calculating a correction value applied to the same and method of correcting grayscale data
