Abstract: A signal compensator includes an abnormality identification unit and a signal compensation unit. The abnormality identification unit is configured to determine whether or not a waveform of a signal generated by a signal generator is abnormal, when the waveform of the signal is normal, output the signal to a display panel, and when the waveform of the signal is abnormal, stop outputting the signal to the display panel and send an instruction to the signal compensation unit. The signal compensation unit is configured to perform signal compensation on the display panel in accordance with the instruction received from the abnormality identification unit.
