Light-emission device with an OLED element

摘要

A light-emission device with a two-dimensional OLED element and an encapsulation element for protecting the OLED element. The light-emission device furthermore has a support, on which the OLED element is arranged in such a way that the encapsulation element points toward the support, and an electrical conductor element for an electrical connection between the support and the OLED element. wherein the electrical conductor element is elastic in a normal direction to the OLED element. By way of example, the conductor element can be helical. As a result of the elastic property thereof, the conductor element can absorb mechanical tension while ensuring reliable electrical contacting. Hence, this can reduce or even avoid the risk of the electrical connection between the support and the OLED element being disadvantageously influenced or impaired by forces which can occur when handling the light-emission device or which can be generated by temperature variations.
