a transparency adjusting layer configured to adjust transparency of the display substrate and formed on a second surface of the substrate body, wherein the first and second surfaces are opposing each other, and wherein the controller unit comprises an operating unit, a first communication unit, and a memory.
11. The display of claim 10 further comprising a fixing clip including a second communication unit configured to communicate data with the controller unit and a slot so as to fix the ends of the display substrate together.
12. The display of claim 11 , wherein the fixing clip comprises a fingerprint recognition unit, and wherein the memory of the controller unit stores fingerprint information of a user.
13. The display of claim 1 , wherein the display substrate further comprises a film scanner formed on the substrate body and configured to scan an image.
14. The display of claim 13 , wherein the display substrate comprises a touch screen panel.
15. The display of claim 14 , wherein the film scanner is configured to generate scanning information based on the scanned image, wherein the touch screen panel is configured to generate touch information based on objects drawn on the touch screen panel, and wherein the controller unit is configured to i) receive the scanning information and the touch information and ii) combine the scanning information and the touch information so as to display a combined image.
16. A foldable display comprising:
a foldable display substrate;
a driver configured to drive and detachably connected to the display substrate; and
a controller configured to control the driver and detachably connected to the driver,
wherein the foldable display substrate comprises:
a touch screen panel configured to generate touch information based on a user's touch; and
a film scanner configured to scan an image placed below the display substrate and generate scanning information,
wherein the controller is further configured to receive and combine the scanning and touch information so as to display a combined image on the touch screen panel.
17. The display of claim 16 , wherein the display substrate further comprises:
a substrate body;
a display element formed on a first surface of the substrate body; and
a transparency adjusting layer configured to adjust transparency of the display substrate and formed on a second surface of the substrate body, wherein the first and second surfaces are opposing each other.
18. The display of claim 17 , wherein the display element comprises an organic light-emitting diode (OLED), and wherein the transparency adjusting layer comprises liquid crystal molecules.
