Apparatus and method for driving liquid crystal display panel

A data driver IC for driving a liquid crystal display panel including first and second gate lines;

• a data line;
• and a pixel including a first sub-pixel connected to said data line and said first gate line and a second sub-pixel connected to said data line and said second gate line, said driver IC comprising:
• a gamma correction circuitry generating first gamma-corrected data by performing gamma correction on externally-received image data in accordance with a first gamma curve and generating second gamma-corrected data by performing gamma correction on said image data in accordance with a second gamma curve;
• and
• a drive circuitry driving said data line in response to said first gamma-corrected data in a first horizontal period and driving said data line in response to said second gamma-corrected data in a second horizontal period following said first horizontal period.

A method of driving a liquid crystal display panel including first and second gate lines;

• a data line;
• and a pixel including a first sub-pixel connected to said data line and said first gate line and a second sub-pixel connected to said data line and said second gate line, said method comprising:
• externally feeding image data to a data driver IC;
• generating first gamma-corrected data within said data driver IC by performing gamma correction on said image data in accordance with a first gamma curve;
• generating second gamma-corrected data within said data driver IC by performing gamma correction on said image data in accordance with a second gamma curve;
• driving said data line in response to said first gamma-corrected data in a first horizontal period;
• and
• driving said data line in response to said second gamma-corrected data in a second horizontal period following said first horizontal period.
