Light Converging Sheet Unit |
摘要 |
A light converging sheet unit includes first and second light converging sheets stacked one on top of the other. The first light converging sheet has first light converging micro-prism structures with a first average peak-to-peak distance between adjacent ones of the first light converging micro-prism structures. The second light converging sheet has second light converging micro-prism structures with a second average peak-to-peak distance between adjacent ones of the second light converging micro-prism structures. At least one of the first and second average peak-to-peak distances is not larger than 35 μm.
