a Optical images of the dynamic operation of micro-LED display using external driving circuit, representing the letters ‘L,’ ‘E,’ and ‘D’. Scale bar: 2 mm. b Optical image of full-color micro-LED display after peeling off from the carrier substrate. Scale bar: 5 mm. c Optical image of RGB micro-LED display, when bent by tweezers. Scale bar: 5 mm. d Photograph of ultrathin RGB micro-LED display on a glass rod with 3 mm radius. Scale bar: 6 mm. e Current–voltage curves of micro-LEDs, when bent with R = 3 mm. f Relative voltage change of micro-LED during cyclic bending test with a bending radius of 3 mm. The injected current during the test is fixed at 100 μA.
