Abstract
An electroluminescent display device having a plurality of pixels is disclosed. Each pixel includes a driving transistor having a gate connected to a first node, a source connected to a third node, and a drain connected to a fourth node, to generate pixel current corresponding to a data voltage when a high-level source voltage is applied to the third node, a light emitting element connected between the fourth node and an input terminal for a low-level source voltage, an internal compensator including first and second capacitors, and switching transistors, and a kick-back compensation transistor to apply a DC voltage higher than an initialization voltage to the first node in a kick-back compensation period between an initialization period and a data writing period.
