OPTICAL LAMINATE, OPTICAL DEVICE, AND METHOD FOR PRODUCING OPTICAL LAMINATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052207 titled 'OPTICAL LAMINATE, OPTICAL DEVICE, AND METHOD FOR PRODUCING OPTICAL LAMINATE
Simplified Explanation
The patent application describes an optical stack that includes a first optical sheet with a concavo-convex structure and a second principal face. An adhesive layer is applied to the first principal face of the first optical sheet. The concavo-convex structure consists of multiple dents and flat portions between them. The adhesive layer is in contact with the flat portions, creating internal spaces within the dents. The area ratio of air voids at the interfaces between the flat portions and the adhesive layer to the area of the first optical sheet is 3% or less.
- The optical stack includes a first optical sheet with a concavo-convex structure and a second principal face.
- An adhesive layer is applied to the first principal face of the first optical sheet.
- The concavo-convex structure consists of multiple dents and flat portions.
- The adhesive layer is in contact with the flat portions, creating internal spaces within the dents.
- The area ratio of air voids at the interfaces between the flat portions and the adhesive layer to the area of the first optical sheet is 3% or less.
Potential Applications:
- Display technology: The optical stack can be used in displays to enhance image quality and reduce glare.
- Optical lenses: The concavo-convex structure can be utilized in lenses to improve optical performance and reduce aberrations.
- Solar panels: The optical stack can be applied to solar panels to increase light absorption and efficiency.
Problems Solved:
- Glare reduction: The concavo-convex structure and adhesive layer help reduce glare and improve visibility in displays and lenses.
- Optical performance improvement: The internal spaces within the dents enhance light transmission and reduce optical distortions in lenses and displays.
- Efficiency enhancement: The optical stack can increase light absorption in solar panels, improving their energy conversion efficiency.
Benefits:
- Improved image quality: The optical stack reduces glare and improves visibility, resulting in enhanced image quality in displays and lenses.
- Enhanced optical performance: The concavo-convex structure and adhesive layer improve light transmission and reduce optical distortions, leading to better optical performance.
- Increased energy efficiency: The optical stack increases light absorption in solar panels, improving their energy conversion efficiency and overall performance.
Original Abstract Submitted
an optical stack includes: a first optical sheet having a first principal face with a concavo-convex structure and a second principal face at an opposite side from the first principal face; and an adhesive layer that is disposed on the first principal face of the first optical sheet. the concavo-convex structure includes a plurality of dents and flat portions between adjacent ones of the plurality of dents. the adhesive layer is in contact with the flat portions. a surface of the adhesive layer and the first principal face of the first optical sheet together define an internal space within each of the plurality of dents. in a plan view from a normal direction of the first principal face of the first optical sheet, an area ratio of air voids existing at interfaces between the flat portions and the adhesive layer to an area of the first optical sheet is 3% or less.
