Abstract
A liquid discharging apparatus includes a liquid discharging head that discharges liquid from a nozzle, and a driving signal substrate that inputs, to the liquid discharging head, a driving signal according to waveform data. The liquid discharging head includes a driving element that drives the nozzle, switching elements connected to the driving element, a signal transmitter connected to the driving element via the switching elements and including signal lines through which the driving signal is transmitted according to waveform data, and a potential difference detector that detects a potential difference based on an intermediate potential of the driving signal transmitted through each signal line. The liquid discharging apparatus generates a correction signal based on the potential difference; corrects the waveform data based on the correction signal; generates the driving signal based on the corrected waveform data; and outputs the generated driving signal to the corresponding signal line.
