His innovative contributions primarily focus on the domain of electrophoretic displays, showcasing his expertise in combining various chemical compositions to enhance display technology.

Latest Patents

Among his latest patents, two significant inventions stand out: both revolve around "Encapsulated dispersions comprising electrophoretically mobile organic colorants." The first patent details an electrophoretic display that includes electrodes and cells with ionic, monochrome particles combined with a non-polar liquid and a dispersant. The innovative aspect lies in the configuration of the ionic particles, which are aggregates made up of carbon-containing pigments and cationic pigments or derivatives. The patent emphasizes achieving at least 80% of the cationic pigment within the aggregates for optimal performance.

Similarly, the second patent addresses electrophoretic displays but employs anionic pigments instead of cationic ones. Just like the first, it integrates electrodes and cells containing monochrome particles in a non-polar liquid, with the dispersant still chosen from a specific group of polymers. The focus remains on ensuring that the majority of the anionic pigments are incorporated into the aggregates, achieving improved efficiency and color mobility in display technology.
