Future lighting applications will strongly benefit from transparent luminescent devices. Here, we demonstrate transparent organic light-emitting diodes (OLEDs), which provide real-time adjustment of the emission color. Making use of the AC/DC concept

Organic light-emitting diodes (OLEDs) are scalable area light sources which can be designed to emit a variety of spectral distributions in the visible part of the electromagnetic spectrum. Typically, the emission pattern is close to be of Lambertian

A device concept for highly efficient OLEDs is introduced that allows to tune the emission color of the device over a broad range of the CIE color gamut. The approach exploits the different polarities of the positive and negative half-cycles of an al

We report on a novel approach to obtain white emission from organic light-emitting devices, which require no charge injection from external electrodes and instead use a capacitively coupled alternating current driving signal for device operation. In

We report efficient and bright organic light-emitting devices operated by capacitive energy coupling. In this approach, the organic layers are enclosed between sputter-deposited hafnium dioxide layers to prevent charge carrier injection. When a sinus

Organic light-emitting diodes (OLEDs) have gained considerable attention because of their use of inherently flexible materials and their compatibility with facile roll-to-roll and printing processes. In addition to high efficiency, flexibility and tr
