Patent ID: 8094253

Claim:
A driving method of a display device, the display device including display elements arranged in a form of a two-dimensional matrix in a first direction and a second direction, the display elements each having a driving circuit and a current driven type light emitting section, the driving circuit including at least a driving transistor having a gate electrode and source/drain regions and a capacitance section, and a current flowing through the light emitting section via the source/drain regions of the driving transistor, the driving method comprising the step of: in a state of a predetermined driving voltage being applied to one source/drain region of the driving transistor, performing a first writing process of applying a first video signal to the gate electrode of the driving transistor, next performing a second writing process of applying a second video signal to the gate electrode of the driving transistor, and then setting the gate electrode of the driving transistor in a floating state, whereby a current corresponding to a value of a voltage retained in the capacitance section for retaining a voltage of the gate electrode of the driving transistor with respect to a source region of the driving transistor flows through the light emitting section via the driving transistor, so that the light emitting section emits light; wherein length of a period during which the first video signal is applied to the gate electrode of the driving transistor is adjusted in the first writing process, whereby luminance of light emitted by the light emitting section is controlled on a basis of a value of the first video signal, a value of the length of the period during which the first video signal is applied to the gate electrode of the driving transistor, and a value of the second video signal.
