A phosphor binding material and process is shown and described for LCD backlight systems. The improved process provides a residual phosphor binding material transparent to UV light. No UV light energy is lost to absorption in the binding material and more UV light energy is used to produce visible light. Because the UV light is better utilized in the production of visible light, overall lamp efficiency is improved.

La présente invention concerne un liant au phosphore ainsi que le procédé associé décrit pour des systèmes à rétro éclairage dans des afficheurs à cristaux liquides (LCD). Dans ce procédé perfectionné, le liant au phosphore résiduel est transparent à l'ultraviolet (UV). Aucune énergie de lumière ultraviolette n'est perdue en absorption dans le liant, et une plus grande énergie de lumière UV est disponible pour la production de lumière visible. Cette meilleure utilisation de la lumière ultraviolette (UV) pour la production de lumière visible confère à la lampe une efficacité globale accrue.
