Abstract

A display device is disclosed. The display device includes a display panel and a driving chip. The display panel includes at least a first display area and a second display area arranged side by side along a first direction. In the present application, by controlling any two adjacent display areas to scan toward each other or to scan away from each other, at least one scanning lines in the first display area and at least one scanning lines in the second display area simultaneously receive driving signals input from the driving chip.
