GE has ushered in a new breakthrough by inkjet-printing narrow-band red (PFS-KSF) and green phosphors for future display applications.
These advances were announced by Dr. James Murphy – a senior scientist at GE Research – during the display industry’s largest conference, the SID Virtual Display Week Business Conference.
As part of his keynote presentation, Murphy showed a video of a new inkjet-printed red phosphor on a plastic substrate that he says illustrates advances toward printing phosphors for micro- and mini- LED displays.
“GE’s Research Lab has been innovating in 3D printing technologies, including direct write, or inkjet-printing technologies, for several decades,” notes Murphy.
“We tapped into the Lab’s deep experience with these 3D, or additive processes, and came out with an exciting breakthrough that will pave the way for our narrow-band red and green phosphors to be used in next generation micro and mini- LED displays.”
According to the GE report, as of today, there have been nearly 40 billion PFS-KSF containing LEDs sold into commercial displays.
While LEDs are expected to continue to dominate in the near-term, the micro and mini-LED markets are rapidly growing.
“Today, if you were to look at any of your electronic devices, TVs or computer screens, there’s a better chance than not that it includes GE’s phosphor technology inside,” says Murphy.
“But we know the next generation of display applications is coming, and we want to do everything we can to maintain and build upon our present market position well into the future.”
According to Murphy, the new PFS/KSF platform includes improved resistance to water/humidity; smaller particle size; and improved formulation for incorporation into both on-chip and remote configurations.
Taken together, this could pave way for more immersive and color rich LCD displays.
