Abstract: Disclosed is an electroluminescent display device including a display panel, a power supply unit, and a data driver. The display panel includes a subpixel for displaying an image. The power supply unit supplies a positive voltage and a negative voltage to the display panel. The data driver supplies a first initialization voltage and a second initialization voltage to the display panel, as well as a data voltage, and at least one of the first initialization voltage and the second initialization voltage is varied.

Abstract: 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.
