Display device and driving method thereof

A display device comprising:

• a display panel configured to display an input image across a first subpixel region and a second subpixel region;
• a display panel driver configured to supply pixel data of the input image to subpixels of the display panel;
• a light source disposed under the display panel in an area overlapped by the second subpixel region;
• and
• a controller configured to drive the light source in an emission permitting section set within a non-driving period of a group of subpixels among the subpixels that are disposed in at least a portion of the second subpixel region,
• wherein a scan pulse is supplied to subpixels in the first and second subpixel regions and is maintained in a gate-off voltage during the emission permitting section, and
• wherein the controller is further configured to turn the light source off before an initialization period of the group of subpixels in the second subpixel region.
