1. A flexible display device, comprising:
- a display unit comprising a first display area and a second display area bendable with respect to the first display area, the second display area comprising a bending area bendable and a flat area having a flat form, the bending area connecting the flat area to the first display area;
a control unit coupled to the display unit, the control unit performing a correction of at least one of a brightness and a color coordinate of an image to be displayed in at least one of the first display area and the second display area according to a degree of bending between the first display area and the second display area, a degree of the correction of a first pixel in the second display area being larger than a degree of the correction of a second pixel in the second display area when the first pixel in the second display area is disposed farther from the first display area than the second pixel in the second display area, both of the first pixel and the second pixel being in the same flat area of the second display area; and
a backplate attached to one side of the display unit to be bent together with the display unit, the backplate comprising;
a bendable housing unit; and
a metallic plate embedded in the housing unit, the metallic plate comprising a bent portion disposed at the interface between the first display area and the second display area, wherein the metallic plate maintains a bent form even when the display unit is not bent.

11. A method of controlling a flexible display device including a first display area and a second display area bendable with respect to the first display area, the method comprising:
-
measuring a degree of bending between the first display area and the second display area, the second display area comprising a bending area bendable and a flat area having a flat form, the bending area connecting the flat area to the first display area; correcting at least one of a brightness and a color coordinate of an image to be displayed in at least one of the first display area and the second display area according to the degree of bending to produce a corrected image, a degree of said correcting at a first pixel in the second display area being larger than a degree of said correcting at a second pixel in the second display area when the first pixel in the second display area is disposed farther from the first display area than the second pixel in the second display area, both of the first pixel and the second pixel being in the same flat area of the second display area; and displaying the corrected image, wherein the flexible display device comprises a backplate attached to one side of the display unit to be bent together with the display unit, the backplate comprising; a bendable housing unit; and a metallic plate embedded in the housing unit, the metallic plate comprising a bent portion disposed at the interface between the first display area and the second display area, wherein the metallic plate maintains a bent form even when the display unit is not bent. - View Dependent Claims (12, 13, 14, 15, 16)
