Title:
画素回路の駆動方法、電気光学装置および電子機器
Document Type and Number:
Japanese Patent JP4737120
Kind Code:
B2
Abstract:
There is provided a method for driving a pixel circuit including a light-emitting element that emits light whose amount corresponds to a driving current, a driver transistor that supplies the driving current to the light-emitting element, a first transistor provided between a gate of the driver transistor and a drain of the driver transistor, a second transistor provided between the drain of the driver transistor and a node used to supply an initialization potential, and a capacitive element one terminal of which is connected to the gate of the driver transistor. In an initialization period in which the first transistor is turned on, the method for driving a pixel circuit includes supplying a fixed potential to the other terminal of the capacitive element and supplying a predetermined potential allowing the second transistor to be operated in a saturation region thereof to a gate of the second transistor. In a writing period after the initialization period is finished, the method for driving a pixel circuit includes supplying a potential corresponding to a gradation to be displayed to the other terminal of the capacitive element.
