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.

Abstract: A display driving circuit including a reference voltage generator configured to generate a plurality of reference voltages, a buffer circuit configured to generate an output voltage based on a reference voltage, from among the reference voltages, applied to an input node thereof, and a precharging circuit configured to precharge the input node based on a first control signal in a transition period, which is a time period between a first point in time at which a first reference voltage is applied to the input node and a second point in time at which a second reference voltage is applied to the input node, may be provided.
