GE to manufacture TriGain^™, GE’s family of enhanced potassium fluorosilicate (PFS) phosphors for use in LED-based display backlight applications. The TriGain family of phosphors offers improved narrow red band performance, resulting in reds that are sharper and cleaner, enabling richer picture quality and increasing the color gamut for backlit displays. Samples of TriGain may now be obtained from GE Lighting with production quantities available in mid-2015.

The “perfect red” has eluded LED display manufacturers, who must often choose between brightness and appearance. With TriGain, there is no need for compromise—reds are brighter and make other colors clearer, producing enhanced picture quality in LCD smartphones, tablets and TV’s. And, as only GE has the patents on the use of PFS phosphor in an LED package, the company has decided to manufacture and supply TriGain to complement the growing use by its licensees.

“This breakthrough was only possible through GE’s prevailing leadership in the advancement of LED technology,” said Jerry Duffy, GE Lighting Global Product General Manager. “Adding to the breakthrough is GE’s proprietary improvements to phosphor synthesis, including decreased particle sizes, higher quantum efficiencies and longer life when compared to standard PFS. Many devices currently on the market offer lower-quality red components in LED—what GE has achieved technically will turn the tide toward more vibrant color in a range of consumer electronics.”

Grounded in GE’s expertise and capability in material science, TriGain phosphors will be manufactured through GE’s proprietary processes at a Cleveland-based GE Lighting facility.
