An electroluminescent display device is composed of a plurality of rows of
pixels, each at least including a light emitting element, a switching
transistor, and a driving transistor electrically coupled to the
switching transistor and the light emitting element. A frame image is
shown on the electroluminescent display device in a display period having
a first time interval, a second time interval, and a third time interval.
These rows of pixels are activated in order during the first time
interval and the second time interval. And then, a display data is
provided for these rows of pixels during the first time interval,
subsequently a gray level data is provided for these rows of pixels
during the second time interval, then these rows of pixels are reset
during the third time interval.
