7. manufacture method according to claim 5, it is characterized in that, in described step (2), three-roller type coating system comprises glue groove (40), sizing material roller (41), metering roll (42) and applicator roll (43), can regulate the differential surface speed between three-roller type coating system sizing material roller (41), gap between metering roll (42) and applicator roll (43) and each roller; Sizing material roller (41) is located in glue groove (40), metering roll (42) adjacent on sizing material roller (41) and sizing material roller (41) reverse rotation, applicator roll (43) adjacent on metering roll (42) and metering roll (42) reverse rotation; Base material (21) obtains band gum base materials (60) after the gluing of three-roller type coating system; Glue groove (40) carries heating system, sizing material roller (41), metering roll (42) and applicator roll (43) band hollow cyclic water channel, in coating process, water is heated to design temperature through boiler, delivers to the hollow cyclic water channel of each roller through water pump.
8. manufacture method according to claim 5, it is characterized in that, in described step (2), the shaping structures system of described prism structural layer (22) comprises front pinch roller (61), patterned roll (62), rear pinch roller (63), band gum base materials (60) after the gluing of three-roller type coating system, in the gap between front pinch roller (61) and patterned roll (62), a hydrops groove can be formed at this gap location, front pinch roller (61) material is rubber, by adjustment rubber hardness and front pinch roller (61) surface temperature, can gap length between indirect regulation patterned roll (62) and front pinch roller (61), thus can the thickness of control cincture gum base materials (60) structural sheet, by effective control of front pinch roller (61) and rear pinch roller (63), effective guarantee band gum base materials (60) fits tightly with patterned roll (62), thus ensure that the structure in patterned roll (62) can effectively be transferred on band gum base materials (60) glue layer, thus form the structural sheet with patterned roll (62) surface micro-structure complementation, in moulding process, the UV light source (64) of patterned roll (62) lower end is cured glue structure, thus obtains prism structural layer (22).
9. manufacture method according to claim 5, is characterized in that, in described step (2), described prism structural layer (22) and anti-blu-ray layer (20) are arranged on base material (21) second optical surface; Anti-blu-ray layer (20) is set on base material (21) second optical surface, prism structural layer (22) is set on anti-blu-ray layer (20); Described prism structural layer (22) is made up of multiple prism monomer, and prism monomer is horizontally disposed with along its length mutually.
10. manufacture method according to claim 5, is characterized in that, in described step (1), described rare-earth luminescent material and polyurethane based resin weight part ratio are 0.05 ~ 0.2:1;
Or rare-earth luminescent material, silicone based resin and acrylic resin weight part ratio are 0.05 ~ 0.2:0.3 ~ 0.5:0.5 ~ 0.7.
