Claim 6:
7. A display device, comprising:
a display panel configured to display an image;
a storage module configured to store an initial load resistance of a data line of the display panel; and
a source driver configured to compensate a signal to be output according to a change in a load resistance of the display panel,
wherein the display panel comprises a plurality of data lines and a load resistance measuring line disposed on some of the plurality of data lines,
wherein the source driver comprises:
an output buffer configured to output a signal to the plurality of data lines;
an output controller configured to control an output of the output buffer;
a load resistance measuring unit configured to measure a load resistance of the at least some of the plurality of data lines through the load resistance measuring lines; and
a comparison unit configured to receive the initial load resistance of the at least some of the plurality of data lines from the storage module and compare a load resistance measured by the load resistance measuring unit with the initial load resistance, and
wherein the output controller is further configured to control a signal to be output by the output buffer to the at least some of the plurality of data lines based on a comparison result.
