Abstract
Disclosed are a foldable display device and a drive method thereof. Control switch units of one column are respectively located in the first display region (100) and the second display region (200) and located adjacent to the sub pixels (10) of two columns, and each scan line is correspondingly coupled to one of the control switch units, and the control switch unit activates or deactivates the second and the third display regions under control of a control signal (En). As performing folding display, the control signal (En) provides a deactivation signal to deactivate all the control switch units, and the scan signal (Scan) is only transmitted to the first display region (100), but not transmitted to the second and the third display region (300, 500), and thus the first display region (100) emits light, and the second display region (300) and the third display region (500) do not emit light.
