Abstract: A display device includes a display panel including a plurality of pixels which display an image, a panel driver which generates a driving voltage based on a plurality of feedback voltages sensed from the display panel to drive the display panel, and a plurality of sensing lines which are connected to the pixels to sense the feedback voltages, respectively, and apply the sensed feedback voltages to the panel driver. The panel driver generates an average feedback voltage corresponding to an average of the feedback voltages and generates the driving voltage based on the average feedback voltage.

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.
