Abstract: A display panel driver includes an adjustment value generation part configured to generate a first adjustment value and/or a second adjustment value based on pre-adjustment luminance values associated with pixels of a display panel, the pixels including a first pixel. The display panel driver further includes an adjustment part configured to receive image data associated with the first pixel for providing a first data signal. The adjustment part may generate the first data signal by adjusting the image data based on the first adjustment value if an input grayscale value associated with the first image data is greater than a reference value. The adjustment part may provide the image data as the first data signal or generate the first data signal by adjusting the image data based on the second adjustment value if the input grayscale value is equal to or less than the reference value.

Abstract: A display panel driver that includes a compensating value generating part, a compensating lookup table and a compensating part. The compensating value generating part generates an offset and a compensating grayscale based on luminances of pixels of a display panel. The compensating lookup table stores the offset and the compensating grayscale. The compensating part compensates an input grayscale of the pixel to generate a data signal using the compensating lookup table.
