发明名称 Pixel circuit, light-emitting device, and image forming apparatus
摘要 A pixel circuit includes a light-emitting element which emits light having the intensity corresponding to an amount of a driving current; a driving transistor which supplies the driving current to the light-emitting element; a storing circuit which writes a data signal instructing the light-emitting brightness of the light-emitting element during a writing period of time to store the data signal; and a buffer circuit which supplies a signal output from the storing unit to the driving transistor.
