Abstract
En 中文
We fabricated an array of organic LED (OLED) pixels on a dome of clear polymer foil. The array is first formed on the flat polymer substrate and then is shaped to the dome. During the shaping process, the polymer substrate and the metal interconnect undergo plastic deformation while the OLED pixels remain intact. The OLED pixels have comparable -1-V characteristics before and after deformation, but the luminous efficiency was reduced by the deformation, apparently as a consequence of fractures in the aluminum cathode. The demonstration of OLED displays on a spherical surface is an important advance in the fabrication of conformally shaped electronics.
