Latest Patents

Kashima holds a patent for a "Method for producing color-converting light-emitting device using electrophoresis." This method provides a solution to prevent the deposition of elements caused by ion migration during the electrophoresis process used to deposit a phosphor layer on the light-emitting device. The process involves placing an anode and a light-emitting device with a semiconductor light-emitting element in a solution containing dispersed phosphor particles. By applying a DC voltage between the light-emitting device and the anode, the particles can be effectively moved to the surface of the semiconductor light-emitting element for deposition. This innovative approach also includes the use of an auxiliary cathode to attract cations and prevent unwanted deposition on the light-emitting device.
