title: Large-area and thin light guide plates fabricated using UV-based imprinting.
abstract: As the demand of larger and thinner flat panel display increasing, conventional methods such as injection molding and hot embossing to fabricate light guide plates (LGPs) become difficult and unsuitable. This study reports a low-cost and high-throughput method to fabricate large-size (320 mm x 240 mm, 15" in diagonal) LGPs by using UV-based imprinting process. With the UV-based imprinting process, a large-size LGP with thickness down to 0.8 mm has been successfully fabricated. The optical property of fabricated LGP has been verified. This study has demonstrated the fabrication of large-size and thin LGPs by using UV-based imprinting process, and the possibility of UV-based imprinting process for fabricating other large thin optical elements.
