Problems solved by technology

For this reason, the number of charging and discharging in each signal line increases, and the power consumption of a signal output unit (so-called signal driver) for supplying a reference voltage and a signal voltage to the signal line increases
In other words, there is currently a problem that the power consumption of the signal output unit and further the power consumption of the display device increases with the correction operation of display unevenness caused by changes in the characteristics of elements constituting the pixel circuit.

Abstract

The invention relates to a display device, a driving method of the display device and an electronic apparatus including the display device. The display device includes a pixel including a driving. A display frame period consisting of a first period and a second period are provided, a duration of the second period is longer than the first period and set as a period obtained by subtracting the first period from the display frame period, a threshold correction for the driving transistor during the first period is performed, and a signal voltage is written in the pixel during the second period. Thus, power dissipation of correction operation of nonuniform display caused by characteristic changes of elements forming a pixel circuit can be reduced.

Description

Technical field [0001] The present invention relates to a display device, a driving method of the display device, and an electronic device, and more particularly to a flat (flat panel) display device, a driving method of the display device, and an electronic device including the display device. The flat display device is a matrix It is formed by two-dimensionally arranging pixels (pixel circuits) including light-emitting units. Background technique [0002] As a flat display device, there is a display device that uses a current-driven electro-optical element as a light-emitting unit. The light-emitting brightness of the current-driven electro-optical element increases with the current flowing through the light-emitting unit (light-emitting element). Value changes. As a current-driven electro-optical element, for example, an organic electroluminescence (EL) element is known, which is luminescence caused by electroluminescence of an organic material when an electric field is appli...
