Abstract
The present invention is directed to the use of a plurality of OLED displays and a diffuser to form a display backlight. Such a backlight can be used as an AMLCD backlight. The OLED displays can support NVIS compatibility by reducing current provided to red sub-pixels, and by limiting transmission of light beyond 630 nm, possibly by material selection or filtering using thin film optical coatings.
