Abstract
The present exemplary embodiments provide a stretchable display which controls an appropriate resolution by disposing a hidden cell below a layer in which an open cell is located using a morphable three-dimensional structure in which LED chips are vertically disposed, rather than a two-dimensional platform of the existing plane, sensing a current change in accordance with a mode switching between a folded mode and a stretched mode while maintaining a state in which an open cell is exposed and the hidden cell is hidden in a folded mode, to automatically turn on/off the hidden cell, and activating the hidden cell in the stretched mode and a manufacturing method thereof.
