Backlight illumination system and display device

A backlight illumination system for illuminating a large area with light of a uniform color has a set of a pre-determined number of light emitters (R,G,B) arranged along a straight line. The set is divided in a plurality of subsets, each subset including at least two light emitters. Each subset comp...

Beschreibung
Zusammenfassung:	A backlight illumination system for illuminating a large area with light of a uniform color has a set of a pre-determined number of light emitters (R,G,B) arranged along a straight line. The set is divided in a plurality of subsets, each subset including at least two light emitters. Each subset comprises light emitters with substantially the same light-emission color point, the respective subsets having color points different from each other. As a first step, the light emitters of the subset with a smallest number of light emitters are assigned to respective substantially equidistant positions. The light emitters of the set are assigned to the respective positions by iteratively starting with the subset with the smallest number of light emitters, assigning the light emitters of the subset to substantially equidistant positions which are not yet occupied. The backlight illumination system according to the invention has a uniform light and color distribution.
