Apparatus and method for driving display panel with temperature compensated driving voltage

An apparatus for driving a display panel with a temperature compensated driving voltage, the apparatus comprising:

• a temperature sensor configured to output temperature data indicating a temperature corresponding to one of a set of predetermined temperature intervals;
• a temperature section register configured to store temperature section data that respectively represents temperature sections when a predetermined temperature range is divided into the temperature sections;
• a comparing unit configured to compare the temperature data to the temperature section data and to output comparison data having predetermined bits;
• a voltage register configured to store voltage data corresponding to different driving voltages, wherein each of the different driving voltages corresponds to one of the temperature sections;
• a voltage controller configured to select voltage data corresponding to the comparison data, from the voltage data stored in the voltage register, and to output a voltage control signal corresponding to the selected voltage data;
• and
• a driver configured to output to the display panel a driving voltage corresponding to the voltage control signal from among the different driving voltages.
