LIQUID CRYSTAL DISPLAY DEVICE

PURPOSE: A liquid crystal display device is provided to reduce the size of a driver integrated circuit by performing the gamma conversion of Red-Greed-Blue(RGB) data using two gamma circuits. CONSTITUTION: A first switching unit(630) outputs selected R data or selected blue data to a first gamma con...

More Information
Summary:PURPOSE: A liquid crystal display device is provided to reduce the size of a driver integrated circuit by performing the gamma conversion of Red-Greed-Blue(RGB) data using two gamma circuits. CONSTITUTION: A first switching unit(630) outputs selected R data or selected blue data to a first gamma converter(610) or a second gamma converter(620). A second switching unit(640) outputs selected G data to the first gamma converter or the second gamma converter. The first gamma converter and the second gamma converter perform a gamma-conversion for the R data, the G data or the B data.
