Title: The Innovations of Jyrki Kimmel: A Pioneer in Display Technology
Introduction
Jyrki Kimmel, based in Tampere, Finland, is a prominent inventor known for his significant contributions to display technology. With a remarkable portfolio of 20 patents, Kimmel has made substantial advancements that enhance the functionality and user experience of visual displays.
Latest Patents
Among Jyrki Kimmel’s recent patents is an innovative apparatus, method, and system designed for use in a display. This invention includes a waveguide featuring a multitude of diffractive sections that effectively coupled an input beam of light. It expands the input beam and subsequently out-couples it, producing an expanded output light beam aimed for use in a reflection-based heads-up display system. The system directs the expanded output light beam towards a curved reflective surface, equipped with non-zero optical power, to reflect an idealized collimated light beam towards a user’s eye.
Another noteworthy patent is the Exit Pupil Expander (EPE). This device is geometrically designed to create angularly varying total internal reflection, allowing light of a specific center wavelength to exit perpendicularly at a shifted wavelength. The EPE functionalities are particularly beneficial in head-wearable imaging devices, such as virtual or augmented reality systems, where light is efficiently in-coupled from a micro-display and out-coupled from the EPE.
