发明内容
本发明的目的就是为了解决上述问题，提供一种透光率优异的棱镜结构PS导光板。
为了实现上述目的，本发明采用如下技术方案：棱镜结构PS导光板，包括入光面以及出光面，所述导光板由PS塑料制成，所述出光面设置棱镜结构，所述棱镜结构具有若干平行设置的、截面呈弧形的突起，两相邻的突起间形成V型沟槽；所述沟槽的深度D为85-115μm，宽度W为325-395μm，所述突起的R角值为203-227度。
优选的是，所述沟槽的深度D为110μm，宽度W为380μm，所述突起的R角值为215度。
优选的是，所述突起截面呈半圆形。
优选的是，所述入光面设置由印刷网点制版印刷成的高反射层结构。
与现有技术相比，本发明具有如下有益效果：本发明出光面亮度高，均匀性及能见度均优异，导光板吸水率低。
附图说明
图1为实施例中棱镜结构PS导光板局部剖视图。
