Abstract
A display driving integrated circuit includes a common voltage buffer configured to provide a common voltage to a display panel and when a line outputting the common voltage and a gate line are short-circuited, apply a first current to the gate line or receive a second current from the gate line; a current generator configured to sum currents respectively corresponding to the first current and the second current and output an output current obtained by the summing; and a current detector configured to convert the output current into an output voltage and output a high or low signal based on a result of comparing the output voltage with a preset voltage.
