Roll-to-roll technology is used to form optoelectronic products because it allows fast, continuous production and a short cycle time. It has become the mass production technology with the most potential for development for the production of plastic products with a microstructure. This study designs and manufactures a composite light guide plate (LGP) to replace a traditional LGP with two pieces of prism sheet. The bottom surface of the composite LGP features dot microstructures and the upper surface features prism microstructures. The optical design is optimized separately for the dot microstructure and the prism microstructure. T he optimum designs are used to produce a composite LGP. One side uses the optimized dot distribution, and the other side uses pyramid microstructures. A PMMA substrate with a thickness of 2 mm is manufactured using roll-to-plate UV-cured embossing. In order to manufacture LGPs with microstructures on both sides, a rolling machine with an adjustment and positioning function is manufactured. Taguchi analysis is used to determine the single-sided optimized parameters. The dot structure is replicated 97% and the pyramid structure is replicated 96%. The proposed design for a composite light guide plate with a double-sided structure significantly increases the central average brightness and the uniformity of luminance.

卷对卷技术用于形成光电产品，因为它可以实现快速，连续的生产和较短的周期时间。它已成为具有微型结构的塑料产品生产中最具发展潜力的批量生产技术。本研究设计和制造了一种复合导光板（LGP），用两块棱镜片代替了传统的LGP。复合LGP的底表面具有点状微结构，而上表面具有棱柱状微结构。光学设计针对点微结构和棱镜微结构分别进行了优化。最佳设计用于生产复合导光板。一侧使用优化的点分布，而另一侧使用金字塔微结构。使用卷对板UV固化压花制造厚度为2 mm的PMMA基板。为了制造在两侧具有微结构的LGP，制造了具有调节和定位功能的轧制机。Taguchi分析用于确定单面优化参数。点结构被复制97％，金字塔结构被复制96％。所提出的具有双面结构的复合导光板的设计显着提高了中心平均亮度和亮度均匀性。点结构被复制97％，金字塔结构被复制96％。所提出的具有双面结构的复合导光板的设计显着提高了中心平均亮度和亮度均匀性。点结构被复制97％，金字塔结构被复制96％。所提出的具有双面结构的复合导光板的设计显着提高了中心平均亮度和亮度均匀性。
