Abstract
A data processing device includes a gamma processor applying a gamma function to grayscale data including red grayscale data, green grayscale data, and blue grayscale data to generate luminance data including red luminance data, green luminance data, and blue luminance data, a first compensation coefficient generator generating a first compensation coefficient, a second compensation coefficient generator calculating a first grayscale ratio of the blue grayscale data and a second grayscale ratio of the red grayscale data, and generating a second compensation coefficient, a data compensation coefficient generator generating a data compensation coefficient by multiplying the first compensation coefficient and the second compensation coefficient, a data compensator generating compensation luminance data by adding the luminance data to a value of the data compensation coefficient multiplied by the luminance data, and an inverse processor generating compensation grayscale data.
