Narrow-Band LED Phosphors Enabling Wide Color Gamut Displays

Walking through your local electronics store, you would likely find that the majority of all high color quality LCD backlight displays (TVs, CPU monitors, cell phones, tablets) contain technology developed at GE Research.  Our LED Phosphors team has world class chemistry and physics expertise as well characterization capabilities that have resulted in commercial successes in both lighting and LCD display technologies.  Multi-million dollar yearly revenue, multiple awards, hundreds of patents, >20 licensees of our patents, along with various publications and invited conference presentations show that this team is on the cutting edge of luminescent material development and can go from concept to invention to commercialization.  At our core, we have synthesis and processing expertise of inorganic powders and the ability to scale these processes in a controlled manner. 

Additionally, we have the expertise to use our unique characterization capabilities to make luminescent materials more reliable for longer lasting and higher quality lighting and display products.  We have both steady state and time resolved spectroscopy, accelerated life tests for improved reliability under high temperature, humidity and blue light flux, particle size analysis, and quantum efficiency and absorbance measurement capabilities to optimize phosphor compositions.  Additionally, our expertise around coating phosphors and surface chemistry allow for improved dispersion in silicones, photoresists and polyacrylates.
