Abstract
A pixel circuit includes a light emitting device, a storage device configured to represent a level of illumination, and a driving device used to drive the light emitting device. Configuring the storage device includes changing a voltage difference across the storage device to a level larger than a threshold voltage of the driving device. The driving device reduces driving of the light emitting device while the storage device is being configured. After the storage device has been configured, the driving device is permitted to drive the light emitting device to emit light having a luminance level corresponding to the level of illumination represented by the storage device.
