A display controlling apparatus has a voltage controlling circuit configured to generate an output voltage signal based on image data. The voltage controlling circuit has a digital/analog converting unit configured to convert the image data into a voltage signal, a comparing unit configured to compare a prescripted voltage digital value and the image data, and an output voltage signal selecting unit configured to select a voltage signal as an output voltage signal based on comparison result of the comparing unit, the voltage signal corresponding to the prescripted voltage value or the voltage signal converted by the digital/analog converting unit.
