Electroluminescent display device

An electroluminescent display device comprising:

• a pixel area including a plurality of sub-pixels displaying an image signal at a specific refresh rate;
• a plurality of ELVDD lines electrically connected to the plurality of sub-pixels;
• a plurality of data lines electrically connected to the plurality of sub-pixels;
• a plurality of scan lines electrically connected to the plurality of sub-pixels;
• a plurality of EM lines electrically connected to the plurality of sub pixels;
• a scan driver sequentially supplying a scan signal to the plurality of scan lines and sequentially supplying an EM signal having a specific duty ratio pattern configured to control a dimming level of the pixel area to the plurality of EM lines;
• and
• a driving circuit electrically connected to the plurality of data lines and the scan driver and configured to control the dimming level according to a dimming control signal,
• wherein in at least one frame period, the specific duty ratio pattern includes a plurality of turn-on pulses of different turn-on duty ratios.
