Abstract
A large part of the light generated in a backlight is usually absorbed in the color filters of the liquid-crystal display. A new backlight system that uses a grating to split the white light into different colors and a lens array to focus this light onto the pixels is presented. The absorbing filters can be eliminated and efficiency is improved. The system is characterized, as well as its different components. © Copyright 2008 Society for Information Display.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
