柔性GaN基发光二极管（LED）已被制造在塑料基板上的柔性显示应用。GaN LED阵列的外延结构使用标准软光刻技术转移到柔性衬底上，并通过金属线连接到源表。为了验证柔性衬底上GaN LED的机械和光学稳定特性，在2000次弯曲循环期间以各种弯曲半径表征其电特性。一种白色发光的荧光粉涂层GaN LED显示了其作为下一代柔性光源的潜力。
The flexible GaN-based light emitting diode (LED) has been fabricated on a plastic substrate for flexible display applications. The epitaxial structures of the GaN LED arrays are transferred onto a flexible substrate using standard soft lithography technology and connected to a source-meter by metal lines. To verify the mechanically and optically stable characteristics of the GaN LEDs on the flexible substrates, the electrical properties are characterized during 2000 bending cycles at various bending radius. A white light-emitting phosphor-coated GaN LED shows its potential as a next-generation flexible light source.
