Illustratively, the switch 17 may be a thin film transistor structure.
Specifically, when the display panel is unfolded, the photosensitive element 12 is turned on under the action of external ambient light, the conducting signal provided by the fixed potential signal end is transmitted to the switch 17 through the conducted photosensitive element 12, the switch 17 is controlled to be conducted, and then the Data lines Data in the first display screen 1 and the second display screen 2 are controlled to be communicated. When the display panel is folded, the photosensitive element 12 is turned off, and the on signal cannot be transmitted to the switch 17, so that the switch 17 is turned off, and the Data lines Data in the first display screen 1 and the second display screen 2 are controlled to be disconnected.
