Abstract
A source driver for a display panel includes an output buffer configured to output a signal to a data line of the display panel; an output controller configured to control an output of the output buffer; a load resistance measuring unit configured to measure a load resistance of at least one data line of the display panel; and a comparison unit configured to compare the load resistance measured in the load resistance measuring unit with an initial load resistance, wherein the output controller is further configured to control a signal to be output by the output buffer based on the comparison result.
