Abstract: An operation method of a receiver, which includes setting a coefficient of an equalizer based on one of a plurality of first codes, setting a coefficient of an amplifier based on one of a plurality of second codes, performing offset calibration by driving the equalizer and the amplifier based on the coefficient of the equalizer and the coefficient of the amplifier, storing an offset code corresponding to a voltage offset generated when the equalizer and the amplifier are driven, determining whether the offset calibration is completed, performing a normal operation of obtaining reception data from an input signal, in response to determining that the offset calibration is completed, and removing the voltage offset based on the offset code, in the normal operation.

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.
