Electro-optic device, method of driving electro-optic device, and electronic apparatus

An electro-optic device including a pixel circuit that includes an electro-optic element and a driving transistor; a first data generation unit that, during a first period when image display operation is not performed, detects a temperature and generates first data which allows control of brightness of an image in accordance with the detected temperature; and a luminance control unit that, during a second period when image display operation is performed, performs control of luminance of the electro-optic element on the basis of the first data which is generated during the first period.

Electro-optic device and electronic device

An illumination device includes an organic EL panel having a light emission layer provided between a first electrode and a second electrode, a power source, a power switcher, a control circuit, and a plurality of power supply portions connected to the first electrode. The control circuit controls the power switcher in such a way that, when a first power supply portion of the plurality of power supply portions is connected to the power source, a second power supply portion is not connected to the power source. The power supply portions that supply power to the first electrode are switched sequentially at a high speed. Therefore, a user will feel as if the illumination device emits light without any unevenness of brightness two-dimensionally.
