Display panel and display device including the same

A display device comprising:

• a display panel including:
• a plurality of data lines,
• a plurality of gate lines crossing the data lines,
• power lines configured to receive different voltages,
• a plurality of first pixel circuits configured to receive a pixel driving voltage and a reference voltage from the power lines, and
• a plurality of second pixel circuits including a power line supplied with the pixel driving voltage and a reference voltage line supplied with the reference voltage, wherein at least one of the plurality of second pixel circuits is configured to short-circuit the power line to the reference line for at least some amount time within a vertical blank period;
• a data driver configured to supply a data voltage to the plurality of data lines;
• and
• a gate driver configured to supply a gate signal to the plurality of gate lines.

A display panel comprising:

• a first type of pixel circuit connected to a power line and a reference voltage line, the first type of pixel circuit being configured to display an image;
• and
• a second type of pixel circuit connected to the power line and the reference voltage line, the second type of pixel circuit being configured as a dummy pixel circuit that does not display an image,
• wherein the second type of pixel circuit includes at least one switch configured to connect the reference voltage line with the power line during a vertical black period to cause a short circuit.
