Fig. 5: Demonstration of Stretchable Passive-Matrix OLED with 3D Pop-Up Structure.

a The overall system setup for the implementation of the stretchable passive-matrix OLED display. On the right side, a simplified schematic diagram is presented that shows the bonded and pop-up pixels composing the 7 × 7 arrays, whose detailed layer configurations are provided in Supplementary Fig. 24. b Schematic diagram of the system setup for demonstrating the passive matrix. c Photographs displaying the characters in “3D OLED” one by one when biaxial system strains of 0%, 25%, and 45% are applied.
