Electroluminescent display device having pixel driving

An electroluminescent display device comprising a plurality of subpixels included in an nth row and each including a pixel driving circuit driven in accordance with an initialization period, a sampling period and a light emission period where n is a natural number, wherein the pixel driving circuit includes:

• a light emitting diode;
• a driving transistor including a gate connected to a first node, a drain connected to a second node, and a source connected to a third node;
• a first switching circuit turned on for the initialization period, providing an initialization voltage to the first node and providing a fixed voltage to the third node;
• a second switching circuit turned on for the sampling period, conducting the first node and the second node, applying a data voltage to the third node and providing the initialization voltage to an anode of the light emitting diode;
• and
• a light emitting control circuit controlled by an emission signal and turned on for the light emission period to provide a high potential voltage to the third node and deliver a driving current to the light emitting diode,
• wherein during the initialization period, a predefined stress is applied to the source of the driving transistor,
• wherein the first switching circuit is controlled by a (n−1)th scan signal applied to subpixels arranged in a (n−1)th row, and the second switching circuit is controlled by a nth scan signal applied to the plurality of subpixels arranged in the nth row, and
• wherein the (n−1)th scan signal and the nth scan signal are overlapped with each other in the sampling period.
