Disclosed is a display device that may include a display panel; and a plurality of drivers that control the display panel to display images and include an image control circuit, the image control circuit including: an average picture level (APL) circuit that analyzes first and second input image data for first and second time intervals and calculates first and second APLs, respectively, wherein the second time interval precedes the first time interval, an adjusted-APL generator that generates an adjusted-APL for the first input image data based on a comparison between the first and second APLs, and a luminance adjustment controller that adjusts a luminance of the display panel for the first input image data based on the adjusted-APL.

Organic light-emission display device without flickering

A flexible display comprises a display panel that includes a flexible substrate and subpixels formed in a display area defined on a surface of the flexible substrate. A data driver is mounted to a data driver area defined on the surface of the flexible substrate. The flexible display can have a connector mounted to a connector area defined on the surface of the substrate. A bent portion of the flexible substrate is between the display area and the connector area and causes the connector area to be bent back towards an other surface of the flexible substrate. A system board can further be electrically connected to the connector mounted on the connector area through a cable.
