Abstract
A display device includes a display panel including a first display area and a second display area adjacent to the first display area, a processor configured to generate first image data corresponding to the first and second display areas for a first mode, and to generate second image data corresponding to the first display area for a second mode, and a display driver configured to drive the display panel in response to the first image data in the first mode, and to drive the display panel in response to the second image data in the second mode, wherein a supplementary image is displayed in at least a portion of the second display area in the second mode.
Claims17
A display device comprising:
- a display panel comprising a first display area and a second display area adjacent to the first display area;
- a processor configured to generate first image data corresponding to the first and second display areas for a first mode, and to generate second image data corresponding to the first display area for a second mode;
- and
- a display driver configured to drive the display panel in response to the first image data in the first mode, and to drive the display panel in response to the second image data in the second mode,
- wherein the display driver comprises an image compensator configured to generate supplementary image data based on the second image data to generate and periodically shift a supplementary image in at least a portion of the second display area that is a folded, rolled, or bent display area in the second mode,
- wherein, in the second mode, the supplemental image is displayed and periodically shifted on a non-visible portion of the second display area that is not exposed to a user and is overlapped by another portion of the display panel that is folded, rolled, or bent over the non-visible portion, and
- wherein the supplementary image corresponds to image data of a boundary pixel column at a boundary of the first and second display areas, and remains the same size as the supplementary image is shifted across the non-visible portion of the second display area during the second mode.
A method of driving a display device, the method comprising:
- selecting one mode from a first mode and a second mode;
- displaying a valid image in a first display area and a second display area, corresponding to the first mode;
- displaying the valid image in the first display area, corresponding to the second mode;
- generating supplementary image data corresponding to at least a portion of the second display area that is a folded, rolled, or bent display area in the second mode, corresponding to the second mode;
- and
- displaying and periodically shifting a supplementary image in the second display area, corresponding to the supplementary image data,
- wherein, in the second mode, the supplemental image is displayed and periodically shifted on a non-visible portion of the second display area that is not exposed to a user and is overlapped by another portion of the display device that is folded, rolled, or bent over the non-visible portion, and
- wherein the supplementary image corresponds to image data of a boundary pixel column at a boundary of the first and second display areas, and remains the same size as the supplementary image is shifted across the non-visible portion of the second display area during the second mode.
