A simplified process to form released thin‐film, microscale GaN based blue light‐emitting diodes (LEDs) from patterned sapphire is described by Xing Sheng and co‐workers in article number 1700239 . These micro‐LEDs are transferred onto copper and polyimide based flexible needle substrates, and their electrical, optical, and thermal characteristics are investigated. Integrated with phosphors, flexible polychromic light emitter arrays are demonstrated.
