Highly aligned polarizer for image display devices
A recently granted patent (Publication Number: US11921369B2) discloses a polarizer designed with a unique composition containing a liquid crystal compound, a first dichroic material, and a second dichroic material. The polarizer features an array structure formed by aggregating molecules of the first and second dichroic materials, arranged periodically within the aggregate. The composition includes a specific range of dichroic material content, ensuring optimal performance of the polarizer. Additionally, the patent highlights the crystal structure formed by the dichroic materials within the array, enhancing the polarizer's functionality.
Furthermore, the patent emphasizes the specific characteristics of the dichroic materials used in the polarizer, including their absorption wavelengths and side chain properties. The disclosed polarizer is suitable for use in image display devices, offering improved performance and stability. The patent also introduces a novel concept of stabilization energy within the polarizer composition, indicating the energy loss when one dichroic material is incorporated into a structure formed of the other material. This innovative approach aims to enhance the efficiency and durability of the polarizer, making it a valuable addition to the field of display technology.
