POLARIZING PLATE AND OPTICAL DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240319425 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 polarizing plate includes a polarizer and a protective film stacked on the light exit surface of the polarizer.
- The protective film comprises a polyester-based base layer and an antiglare layer.
- The protective film has an in-plane retardation of 100 nm to 4,000 nm at a wavelength of 550 nm.
- The protective film has a total haze of 40% to 80% and a ratio of internal haze to external haze of greater than 0 to 0.2.
Potential Applications: - This technology can be used in various optical display devices such as LCD screens, smartphones, and tablets. - It can enhance the visual quality of displays by reducing glare and improving image clarity.
Problems Solved: - The protective film helps reduce reflections and glare on the display, improving visibility in bright environments. - It enhances the overall viewing experience by minimizing distractions caused by external light sources.
Benefits: - Improved visibility and image clarity in various lighting conditions. - Enhanced user experience with reduced glare and reflections on the display. - Protection of the polarizer from external damage, extending the lifespan of the optical display apparatus.
Commercial Applications: - This technology can be applied in the manufacturing of consumer electronics, automotive displays, and medical imaging devices. - It can be used in digital signage, computer monitors, and virtual reality headsets to improve display performance.
Questions about the technology: 1. How does the protective film contribute to reducing glare on the display? 2. What are the specific advantages of using a polyester-based base layer in the protective film?
