POLARIZING PLATE AND OPTICAL DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603928 titled 'POLARIZING PLATE AND OPTICAL DISPLAY APPARATUS
The abstract describes a polarizing plate for an optical display apparatus, consisting of a polarizer and a protective film with specific optical properties.
- The protective film includes a polyester-based base layer and an antiglare layer, providing protection and anti-glare properties.
- The protective film has an in-plane retardation of 100 nm to 4,000 nm at a wavelength of 550 nm, ensuring optimal performance.
- The total haze of the protective film ranges from 40% to 80%, contributing to the overall display quality.
- The ratio of internal haze to external haze is greater than 0 to 0.2, enhancing visibility and reducing unwanted reflections.
Potential Applications: - This technology can be used in various optical display devices such as LCD screens, smartphones, and tablets. - It can also be applied in automotive displays, medical devices, and other electronic gadgets requiring high-quality visual performance.
Problems Solved: - Reduces glare and reflections on the display screen, improving visibility in different lighting conditions. - Provides protection to the polarizer and enhances the overall durability of the optical display apparatus.
Benefits: - Improved display quality with reduced glare and enhanced visibility. - Increased durability and protection for the optical components. - Enhanced user experience with clear and crisp visuals.
Commercial Applications: - This technology can be utilized in the manufacturing of consumer electronics, automotive displays, medical devices, and other optical display products. - It can cater to industries focusing on high-quality visual performance and durability in their products.
