<p>For generating collimated light for illuminating LCD matrices, the backlighting system (10) includes a plurality of lenses (24) arranged in an array on one side of a planar substrate (20), a plurality of luminescent phosphor dots (28) located on the opposite side of the substrate (20) from the lenses (24), each at the focal points of the lens, and a means (30) for stimulating the phosphor dots (28) to emit light. The phosphor dots (28) may be responsive to ultraviolet light in which case a fluorescent lamp (30) adapted for emitting ultraviolet light may be used to stimulate the dots (28) to emit visible light. The visible light is then collimated by the lenses (24) and directed for backlighting a display matrix. <IMAGE></p> |
