Contacting organic optoelectronic component with contacting element, comprises placing contacting element on electrode facing away from a surface of encapsulation and providing first energy input to contacting element using ultrasonic tool

摘要

The method comprises providing an organic optoelectronic component comprising an electrode, which is covered with electrically insulating encapsulation, placing a contacting element (8) on the electrode facing away from a surface of the encapsulation, providing first energy input (10) to the contacting element using an ultrasonic tool (9) such as a sonotrode and removing a part of encapsulation by a mechanical friction between the contact element and the encapsulation, and providing a second energy input into the contact element using the ultrasound tool. The method comprises providing an organic optoelectronic component comprising an electrode, which is covered with electrically insulating encapsulation, placing a contacting element (8) on the electrode facing away from a surface of the encapsulation, providing first energy input (10) to the contacting element using an ultrasonic tool (9) such as a sonotrode and removing a part of encapsulation by a mechanical friction between the contact element and the encapsulation, providing a second energy input into the contact element using the ultrasound tool, and forming an electrical and mechanical connection between the contact element and the electrode. The first energy input has a lower energy than the second energy input. The contacting element is pressed with the encapsulation with a first power for a first time period during the first energy input, and is pressed with the electrode with a second power for a second time period during the second energy input, where the first power is greater than the second power. The encapsulation is a thin-film encapsulation, which has a thickness of 200-5000 nm. The time period is determined by measuring a change of energy from the first energy input to the second energy input. The change of energy is determined by measurement of a contact resistance between the contacting element and the electrode. The contacting element and the electrode are formed with the same material in a connecting region. An independent claim is included for an organic optoelectronic component.
