Electron Beam Patterning for Full-Color HR OLED Displays

OLED microdisplays are increasingly establishing themselves in consumer-ready wearables and data glasses. In order to meet the requirements for higher efficiency, higher contrast, and higher resolutions in these applications, Fraunhofer FEP scientists have developed a new micropatterning approach for OLEDs on silicon substrates. This might eliminate the use of color filters and shadow masks in the future and allow full-color displays to be developed by means of a new process. An increase in efficiency and considerably broader color gamut have already been demonstrated in first experiments. Read more »

Stray Light Correction for Array Spectroradiometers

The core competency of Instrument Systems is providing high performance array spectroradiometers, e.g. the CAS 140D that features highest measurement accuracy and reliability. Quality and accuracy of a spectrometer are extremely important because all radiometric, photometric and colorimetric quantities are calculated from the spectral data. A considerable source of error is the occurrence of stray light in the device. This means that a certain pixel of the array detector is contaminated by radiation other than the targeted spectral component. Read more »

Proof Your Blue Light Hazard Risk: Stray Light Corrected CAS 140D

With the stray light corrected CAS 140D Instrument Systems – as a technical pioneer – is the first to offer an array spectrometer that can reliably assess the blue light hazard from light sources within the prescribed limiting values. Hitherto only double monochromators were recommended for this task, as an underestimation of the blue light hazard was possible in measurements with a spectroradiometer on array spectrometer basis due to stray light. The CAS 140D avoids this in two ways: The optics and mechanics used in the spectrograph block are optimized with regard to disturbing stray light. Additionally, a unique stray light correction matrix is integrated in the calibration procedure. Both innovations combined ensure an up to now unachieved precision in the determination of the blue light hazard with an array spectrometer. Read more »
