Nationstar Optoelectronics and Edison reached KSF global patent authorization and continued to consolidate the high color gamut layout of display backlights

Recently, Nationstar Optoelectronics and Edison Innovation Company successfully signed a global KSF patent licensing agreement. This is the continuation and upgrade of Nationstar Optoelectronics' core patent layout in the field of display backlighting after obtaining GE's global KSF patent authorization in 2016 and 2022.

Edison's KSF display backlight technology patent portfolio originated from Dolby Laboratories' acquisition of GE Licensing's business and was formed after the integration of Dominion Harbor. The achievement of this authorization marks Nationstar Optoelectronics’ deep understanding and continued layout of the display backlight patent landscape.
