Abstract: A display driving device including: a gate driver configured to provide a first gate selection signal to a first gate line of a display panel to select the first gate line; a source driver configured to provide an image signal corresponding to the first gate line to a source line; an Electrostatic Discharge (ESD) detection circuit configured to receive a power supply voltage, determine whether there is an ESD in the power supply voltage and, when the ESD is detected, generate a first detection signal; and a controller configured to receive the first detection signal to generate a masking signal, wherein the gate driver is configured to receive the masking signal and not provide a second gate selection signal to select a second gate line.
