Abstract
Disclosed is an electronic device including a display panel displaying an image, a source driver supplying a source voltage to the display panel, and a display driver integrated circuit (DDI) including a timing controller controlling the source driver. The timing controller may be configured to identify information associated with a luminance of the image and to set a source bias current for controlling a slew rate of the source voltage based on the luminance of the image. Besides, various embodiments as understood from the specification are also possible.
