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 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.
Abstract:
A method of driving a display apparatus including generating first gamma correction data of input data using a first gamma look-up table (“LUT”), determining a Mura correction value of the first gamma correction data, adding the Mura correction value to the input data to generate added input data, generating second gamma correction data of the added input data using the first gamma LUT, and driving a pixel in the display panel using the second gamma correction data of the added input data. The Mura correction value is determined after the gamma correction data is generated, and the generating of the added input data is performed prior to any gamma correction being performed on the input data.

Abstract:
A display panel apparatus includes a display panel and a timing controller, and a data driver. The display panel includes a first subpixel and a second subpixel. The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel. When the second subpixel is determined to be defective, the timing controller generates a compensated grayscale of the second subpixel data. The data driver is configured to apply a precharge voltage to the second subpixel and a charging voltage to second subpixel through a data line, wherein the precharge voltage is based on a grayscale of the first subpixel data and the charging voltage is based on the compensated grayscale of the second subpixel data.
