Liquid crystal display and driving apparatus thereof

A driving apparatus of a liquid crystal display, comprising:

• a logic circuit for classifying n-bit image data inputted from an external device into first and second sections with respect to a boundary gray value and for correcting the n-bit image data into m-bit corrected data based on gamma correction data predetermined by gamma characteristics of the n-bit image data for each of the first and the second sections;
• and
• a storage for storing operation parameters of the logic circuit,
• wherein the logic circuit adds correction values obtained by the correction to the n-bit image data multiplied by four and converts a result of the addition into the m-bit corrected data, and
• the boundary gray value is defined as a gray value corresponding to a maximum magnitude difference between gray values of the source image data and gray values of the first corrected data.

A driving apparatus of a liquid crystal display, comprising:

• a logic circuit for classifying n-bit image data into a plurality of sections on the basis of given number of grays and for correcting the n-bit image data into m-bit corrected data based on gamma correction data predetermined by gamma characteristics of the n-bit image data for each of the sections;
• and
• a storage for storing the gamma correction data at boundary gray values of each of the sections,
• wherein the logic circuit converts the n-bit image data into the m-bit corrected data for each of the sections, and
• the boundary gray values are defined as a gray value corresponding to a maximum magnitude difference between gray values of the source image data and gray values of the first corrected data.
