Fraunhofer IPMS is expanding its portfolio with a high-resolution OLED microdisplay for stationary and portable optical systems. The new 2K OLED microdisplay (2,048 x 2,048 pixels, 9.3 µm x 9.3 µm RGB stripe, and 1.07 inches) is the highest-resolution model in the Fraunhofer IPMS microdisplay family. It is based on the institute’s proprietary high-voltage backplane circuit concept. This technology controls multiple stacked OLEDs, resulting in high brightness. In addition to its expanded ability to drive pixels across a wide dynamic range, the display can be controlled via an on-chip LVDS interface, reducing the number of required interconnects. This enables high data bandwidth and allows for refresh rates of up to 120 Hz. A novel microdisplay module package has been developed to generate all the necessary voltages for the display chip directly on the module, so that only a single supply voltage is needed. This significantly reduces the effort required to integrate it into existing optical systems
