Display device, voltage setting method of display device, and electronic device

A display device comprising:

• a display panel including pixels, each of the pixels including a light emitting element, and the pixels including a first pixel, a second pixel, and a third pixel that emit light with different colors;
• a data driver that provides a data signal to the pixels;
• and
• a power supply that provides an anode initialization voltage to an anode of the light emitting element and provides a first power voltage to a cathode of the light emitting element, wherein
• a frame includes an active period in which the data signal is written to the pixels to emit light, and a blank period in which the pixels emit light without writing the data signal,
• the anode initialization voltage in the blank period and the anode initialization voltage in the active period are different from each other, and
• a change amount of the anode initialization voltage for the second pixel between the active period and the blank period and a change amount of the anode initialization voltage for the third pixel are different from each other.

An electronic device comprising:

• a display panel including pixels, each of the pixels including a light emitting element, and the pixels including a first pixel, a second pixel, and a third pixel that emit light with different colors;
• a data driver that provides a data signal to the pixels based on input image data;
• a processor that provides the input image data to the data driver;
• and
• a power supply that provides an anode initialization voltage to an anode of the light emitting element and a first power voltage to a cathode of the light emitting element, wherein
• the anode initialization voltage changes according to a refresh rate, and
• in case that the refresh rate changes, a change amount of the anode initialization voltage for the second pixel and a change amount of the anode initialization voltage for the third pixel are different from each other.
