Latest Patents
One of Donald Preuss's notable patents is for a multimodal microcavity OLED with multiple blue emitting layers. This invention comprises a multimodal light-emitting OLED microcavity device that includes an opaque substrate, a layer with a reflective surface, and a first electrode over the reflective surface. The design features organic layers for light emission, including a second blue light-emitting layer closer to the reflective surface and a first blue light-emitting layer positioned further away. The distance between the midpoints of these layers is defined as L, and the device also incorporates at least one non-blue light-emitting layer. The semi-transparent second electrode allows light to be emitted through its innermost surface, ensuring that the distance L between the reflective surface and the innermost surface remains constant across the entire light-emitting area. This innovative design results in increased blue emission, making it particularly useful as a light source in microdisplays.
