In this study, we fabricated a programmable disposable OLED device with multi-layered substrate structures for security device. It is designed to destroy the device locally at a desired point that has multi-layered structure of a material with heat reaction. Especially, The difference of thickness of gate-controlling-polymer can manage the turn off voltage that we intended to disposable the divice. In addition, in the case of the multi-layered structure described above, it was also improved the surface stability though the surface roughness and porous structure of paper inherent issues. Through these structue, a stable OLED device was produced in a daily environment and even in a harsh condition like floating on water. But when the security is required, the security device can destroy the device partly and and complete destruction of OLED device. |
