GE Highlights Next Generation PFS/KSF Technologies at Display Week 2019

May 13, 2019
  • Showcases enhancements to its narrow-band red-emitting phosphor (PFS/KSF) and new narrow band green phosphor to enable next generation display technologies such as Mini and Micro- LEDS, and remote film phosphor configurations
  • Latest advances in PFS/KSF LEDs will deliver wider color gamut displays with full-array local dimming capability  
  • Will grow PFS/KSF’s market-leading position in commercial displays, with >30 billion LEDs sold worldwide to date across all major display sectors

SAN JOSE, CA - May 13, 2019 - Aiming to grow its market-leading position in commercial displays, GE Research and GE Licensing today highlighted the latest advances to its PSF/KSF LED platform to enable the next generation of display technologies. The advances will be discussed during a presentation by Dr. James Murphy and Douglas Naab at the annual Display Week 2019 Conference being held this week in San Jose, California.

Phosphors are key materials used to enhance color quality in a wide variety of commercial display and lighting applications. GE has accumulated decades of expertise in phosphors, which supported advances in different consumer and commercial lighting applications for its Lighting business. In partnership with scientists at GE Research, the PFS/KSF phosphor program was launched in 2014. Just five years later, PFS/KSF is a top leader in the commercial display market with over 30 billion LEDs sold worldwide.

“Anytime someone is looking at their mobile phone, computer monitor, tablet or television screen, it’s very likely that GE’s phosphor technology is inside these displays,” said Dr. James Murphy, a Senior Scientist at GE Research. “You could say we help bring good displays to life.”

Dr. Murphy explained that advances in GE’s phosphor technology will provide a more cost-effective path toward wide color gamut LCD displays that are more immersive and richer in color. He explained that PFS/KSF LEDs are today used by most major name brands of consumer electronics in virtually every type of Liquid Crystal Display (LCD) application from smart phones and tablets to laptops/computer monitors and televisions. And he states that this technology and LCDs will continue to dominate the market for the foreseeable future.

“Over the next five years, we believe LCDs will continue to dominate the commercial display market,” Murphy added. “We’re aiming to grow GE’s market position in LCDs and penetrate next generation niche markets such as Mini- and Micro- LEDS, with further enhancements to our red phosphor and the introduction of a narrow band green phosphor.”

These next generation material advancements, Dr. Murphy explains, will enable next generation displays such as Mini-LEDs. Mini-LEDs could exceed 15% of all TV, monitors and automotive displays over the next five years. 

GE has made several improvements to PFS/KSF, including: Improved resistance to water/humidity; smaller particle size; and improved formulation for incorporation into both on-chip and remote configurations, such as phosphor film.  In addition, GE has a narrow band green phosphor under development that it believes that, when combined with PFS/KSF, it will produce displays with unparalleled color quality.
