Abstract
A display driving device comprising: a high supply voltage operation unit that generates an operating current under application of a high supply voltage so as to supply driving voltages to a display panel; a low supply voltage operation unit that operates under the application of a low supply voltage lower than the high supply voltage and controls the high supply voltage operation unit; and a reuse circuit that receives the operating current from the high supply voltage operation unit and supplies the operating current to a ground side via the low supply voltage operation unit so as to apply the low supply voltage to the low supply voltage operation unit.
