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.

Display driving device and a display system including the same

A power converting circuit of a display driver includes a positive voltage generator and a negative voltage generator. The positive voltage generator includes a first capacitive DC-DC converter and a first inductive DC-DC converter, and generates a positive source voltage by selectively using one of the first capacitive DC-DC converter, the first inductive DC-DC converter, or a first external power supply voltage. The negative voltage generator includes a second capacitive DC-DC converter and a second inductive DC-DC converter, and generates a negative source voltage by selectively using one of the second capacitive DC-DC converter, the second inductive DC-DC converter, or a second external power supply voltage.
