Patent attributes
An electroluminescent display device can include a light-emitting element, a pixel drive circuit configured to apply a driving current to the light-emitting element, a power supply configured to provide a power voltage to the pixel drive circuit, a data drive circuit configured to provide a data voltage to the pixel drive circuit, and a gate drive circuit configured to provide a gate voltage to the pixel drive circuit. In addition, the pixel drive circuit includes a driving transistor of which a source electrode is connected to a first node, a drain electrode is connected to a second node, and a gate electrode is connected to a third node, an emission transistor connected between the driving transistor and the light-emitting element, and an initialization transistor connected to the second node.
