Microsystems for Display Technologies
Polymeric effect-carriers and technologies offer new possibilities for display technologies. In this field, we develop e.g. interferometric modulators (IMOD) based on dielectric elastomer actuators (DEA). Compared to Si-based IMOD, which probably constitute the most efficient video-capable full-color E-paper platform now, the DEA-IMOD will broaden the field with the advantage of a much more robust and significantly cheaper monolithic structure with control voltages far below 100 V. In addition, we focus on tactile display concepts based on intrinsically active polymers, which adds a freely programmable keyboard to the displays of tablets, smartphones etc..
Displacement function of the hydrogel-based display: a) The micro-actuators define a form of a foil which are covered with knops, b) 3D-profile of the actuator surface.
