Abstract: A flexible display apparatus includes a first body portion, a second body portion and a driving controller. The first body portion includes a first display area, and the second body portion includes a second display area. The second display area is connected to the first display area. The driving controller is configured to determine a first driving frequency of the first display area and a second driving frequency of the second display area based on a folded angle between the first body portion and the second body portion along a folded line disposed between the first body portion and the second body portion.

Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver which drives the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. In a case where the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.
