Abstract
A rollable display including a flexible display panel having a screen that is separated into an exposed display region and a non-exposed display region. The screen of the flexible display panel is moved using a screen driver, and a moving direction of the exposed display region is controlled to be opposite to a moving direction of the screen, to distribute the stress of pixels, without changing an absolute location of the exposed display region, and to defer degradation of the pixels.
