OPTICAL FILMS FOR DISPLAY SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18570774 titled 'OPTICAL FILMS FOR DISPLAY SYSTEMS

The optical construction described in the patent application consists of an optical film with multiple polymeric layers and an optical retarder placed on top of the film. This construction is designed to work with light that is nearly perpendicular to the surface, covering both the visible and infrared wavelength ranges.

• The polymeric layers in the optical film allow for high optical transmittance (over 60%) for visible light and high optical reflectance (over 60%) for infrared light.
• The optical retarder, when the incident light is polarized in specific directions, provides a retardance of over 1000 nm at visible wavelengths.

Potential Applications: - Display technologies - Optical filters - Anti-glare coatings

Problems Solved: - Enhancing visibility and reducing glare in displays - Improving optical performance in various applications

Benefits: - Increased visibility and clarity - Better control over light transmission and reflection - Enhanced optical performance in different lighting conditions

Commercial Applications: Title: Advanced Optical Films for Display Technologies This technology can be utilized in various commercial applications such as enhancing display screens in electronic devices, improving optical filters for cameras, and developing anti-glare coatings for automotive and architectural use.

Questions about the technology: 1. How does the optical retarder enhance the performance of the optical film? 2. What are the specific advantages of using polymeric layers in the construction of optical films?

Original Abstract Submitted

An optical construction includes an optical film including a plurality of polymeric layers and an optical retarder disposed on the optical film. For a substantially normally incident light and for a visible wavelength range of about 420 nm to about 680 nm and an infrared wavelength range of about 900 nm to about 1100 nm: for the incident light polarized along each of mutually orthogonal in-plane first and second directions. the plurality of polymeric layers has an optical transmittance of greater than about 60% for at least one visible wavelength in the visible wavelength range and an optical reflectance of greater than about 60% for at least one infrared wavelength in the infrared wavelength range. For the incident light polarized along at least one of the first and second directions, the optical retarder has an optical retardance of greater than about 1000 nm at the at least one visible wavelength.
