Thinning the light guide plate from 3 layers to 1 layer | Double in-mold forming
Two vapor deposition boards plus a transparent board are consolidated into a single layer. A thin, high-design light guide plate that also accommodates curved surfaces.
Conventional light guide plates typically consist of a three-layer structure made up of two vapor-deposited plates (front and back) and a transparent plate, which has made the high number of components a bottleneck for thinness and space-saving. Additionally, the method of combining plate materials made it difficult to accommodate three-dimensional shapes, greatly restricting design flexibility. By applying double in-mold forming to the production of light guide plates, both sides of the vapor-deposited foil are transferred within the mold simultaneously during injection molding. This consolidates the conventional three-layer structure into a single molded product, achieving significant thinness and a reduction in the number of components. Leveraging the design freedom unique to injection-molded products, it can accommodate curved and complex shapes that were impossible with traditional methods. This contributes to the high design quality and space-saving of automotive ambient lighting and LED panels for home appliances.
