High-tech Adhesives for Mini- and Micro-LEDs - 1

HIGH-TECH ADHESIVES New display technologies Self-emissive display technologies come with their benefits, including more efficient power consumption, increased robustness, higher brightness, and display-inlaid sensors. These aspects are important for AR and VR devices, as well as automotive interior displays, and have the potential to set these displays apart in the premium segment. For backlit units, miniLEDs are appearing more and more, demanding new materials and technologies besides the usual soldering process. DELOs directional conductive adhesives enable both an electrical and a mechanical connection on flexible and rigid substrates, respectively. This material is inherently electrically conductive in one direction. Its proof-of-concept shows that adhesives or functional polymers can prevent short circuits and thus enable wider openings in printing mask designs. This, in turn, allows designers and engineers to develop innovative display products and applications. About DELO DELO is a family-owned company based in Germany, with a long-proven track record in developing innovative functional materials for LED packaging and display applications. Discuss your project and your requirements with our experts: The continued refinement of our adhesive portfolio, plus our network of equipment manufacturers, chip suppliers, panel makers and research institutions, facilitate alternative processes for the ongoing miniaturization of LED dice. Moreover, adhesive properties can also be tailored to customer-specific processes and needs.
