Abstract:
1. An electro-optical device comprising: (i) a display panel; (ii) a driver; and (iii) a voltage adjusting circuit having: wherein when the voltage comparing circuit detects that the input voltage has changed, (i) the driver: (ii) the control circuit controls the switching unit to switch a conversion circuit when the control signal indicating the change in voltage gain is received; (iii) wherein when the voltage comparing circuit detects that the input voltage has changed, the driver supplies to the control circuit a control signal indicating an increase in voltage gain if the voltage gain of the input voltage is made larger than the voltage gain before detecting the change in input voltage, and when the control circuit receives the control signal indicating the increase in voltage gain, the control circuit controls the switching unit to switch a first conversion circuit to a second conversion circuit that performs conversion into a lower voltage than the first conversion circuit that converted the input voltage before receiving the control signal.
