Title:
発光装置、画素回路の駆動方法および電子機器
Document Type and Number:
Japanese Patent JP5720100
Kind Code:
B2
Abstract:
A light emitting device includes a pixel circuit and a driving circuit, the pixel circuit including a driving transistor, a light emitting element, a first capacitance element interposed between a gate and a source of the driving transistor, a selection transistor, a current generating unit which generates set current. The driving circuit controls the current generating unit to generate set current with a predetermined magnitude in a current set period before a writing period of writing data potential in the pixel circuit, to set the voltage (voltage between both ends of the first capacitance element) between the gate and the source of the driving transistor to a value necessary to allow the set current to flow in the driving transistor.
