Abstract
A light-emitting seal using a self-aligned organic light-emitting diode (OLED) and a laminate process is proposed and demonstrated. This device has a self-aligned ink-jet-printed structure where an insulating material is dissolved in a solvent, and a mixture of organic materials is formed at the same position as that of the ink-jet-printed region. A cathode electrode is laminated onto the above ink-jet-printed structure. The merits of the device are its simple fabrication without the need for photolithography or any vacuum process, and its lower cost. The typical luminance obtained was 6,810cd/m2. The concept of the device is useful for light-emitting seals (LES), tags and graphics with noncontact electromagnetic electric supply but no electric supply line.
