Claim:
A projection assembly comprising: (a) an off-axis fresnel lens comprising: a lens having an input surface on a first side and an output surface on a second side; and a plurality of outwardly-extending, total-internal-reflection type prism facets disposed on the input surface in concentric rows, each facet having a top side and a bottom side that intersect to form a prism peak; (b) a lenticular lens having an input side and an opposing output side, said input side including a plurality of vertical lens arrays and said lenticular lens being made of a material having a first refractive index; (c) a diffuser having an input side and an opposing output side, said input side receiving light transmitted from the lenticular lens' output side; and (d) a clear layer of material having a second refractive index, said clear layer having a first side for receiving light from the output surface of the fresnel lens and an opposing second side that overlays the input side of the lenticular lens.
