Abstract: A display device includes: a display panel which receives a driving voltage and an initialization voltage; a power manager which provides the driving voltage to the display panel; and a voltage generator which receives a feedback driving voltage from the display panel and generates the initialization voltage based on the feedback driving voltage. The feedback driving voltage is a voltage that is fed back to the voltage generator after the driving voltage supplied from the power manager passes through the display panel.

Abstract: A display device includes: a display panel having a first region and a second region defined in the display panel, in which the second region is adjacent to the first region in a first direction. The display panel includes: a first pixel disposed in the first region, a second pixel disposed in the second region, a first bias voltage line electrically connected to the first pixel to transmit a first bias voltage, and a second bias voltage line electrically connected to the second pixel to transmit a second bias voltage. A time point, at which a level of the first bias voltage is changed, differs from a time point at which a level of the second bias voltage is changed, when the display panel operates at a first frame frequency.
