18‐5: The development of splicing‐coated polarizers for TFT‐LCDs

Polarizers are one of the essential components for TFT‐LCDs, which directly determines the image quality of panels. Large‐size TFT‐LCDs have become a new trend in the market in recent years while the size of conventional polarizers limits the growth of ultra‐large size LCDs. The technology of coated polarizers can realize this demand and has the potential to be directly fabricated on glass substrates. In this study, we focused on optimizing the coated process on glass to prepare a large‐size polarizer. Considering the relatively high cost and low yield of a whole‐surface coated polarizer, we proposed a new approach to create a splicing‐coated polarizer by combining conventional polarizer films and coated polarizer. The splicing‐coated polarizer was successfully fabricated at a 32‐inch real panel, proving its high feasibility. This technology demonstrates great potential for integrating next‐generation polarizer films into LCDs.
