摘要： The invention provides an electro-optical device having circuits for driving electro-optical elements, such as organic EL elements, and a driving device, which can employ driving elements having low driving ability, such as α-TFTs. By providing a charge storage capacitor between the source electrode and the gate electrode of a driving transistor which is between power sources, the electro-optical device can allow the driving transistor to control a driving current, even when an electro-optical element is connected to the source side of the driving transistor. In addition, driving data can be stored in the charge storage capacitor by applying a predetermined voltage to the source electrode of the driving transistor.

摘要： An electro-optical device includes a controller, a reference current source, a correction current source, a combining unit, and an electro-optical element. The controller generates a reference current control signal defining a first period during which a reference current is output, and a correction current control signal defining a second period during which a correction current is output, the second period being shorter than the first period. The reference current source generates the reference current based on the reference current control signal. The correction current source generates the correction current based on the correction current control signal. The combining unit combines the reference current and the correction current to generate a driving current. The electro-optical element emits an amount of light corresponding to the driving current. The controller generates the reference current control signal and the correction current control signal so that the second period is shorter than the first period.
