Electronic Device Display Having a Selective Light Redirecting Layer - A simplified explanation of the abstract
This abstract first appeared for US patent application 18258951 titled 'Electronic Device Display Having a Selective Light Redirecting Layer
Simplified Explanation
The abstract of this patent application describes a display system that includes a display panel emitting light, a lens assembly to focus the light towards a viewer, and a light redirecting layer between the display panel and the lens assembly. The light redirecting layer ensures that the lens assembly receives incident light at an optimal angle and redirects light by different amounts at different portions of the layer.
- The light redirecting layer redirects light away from the center and the magnitude of the redirection angle increases with increasing separation from the center.
- The light redirecting layer is a geometric phase lens formed using a liquid crystal film.
- The display system may also include a circular polarizer, an additional circular polarizer, and an additional quarter waveplate.
Potential applications of this technology:
- This display system can be used in various electronic devices such as smartphones, tablets, laptops, and televisions.
- It can enhance the viewing experience by improving the clarity and brightness of the displayed content.
Problems solved by this technology:
- The light redirecting layer ensures that the lens assembly receives incident light at an optimal angle, improving the efficiency of light transmission and reducing light loss.
- By redirecting light away from the center, the display system can reduce glare and improve the overall image quality.
Benefits of this technology:
- Improved viewing experience with enhanced clarity and brightness.
- Reduced glare and improved image quality.
- Increased efficiency of light transmission, resulting in energy savings.
Original Abstract Submitted
A display may include a display panel that emits light. The light from the display panel may be focused by a lens assembly towards a viewer. A light redirecting layer may be included in the display between the display panel and the lens assembly to ensure that the lens assembly receives incident light at an optimal angle. The light redirecting layer may redirect light by different amounts at different portions of the light redirecting layer. The magnitude of the redirection angle may increase with increasing separation from the center of the light redirecting layer. The light redirecting layer may redirect light away from the center of the light redirecting layer. The light redirecting layer may be a geometric phase lens formed using a liquid crystal film. The display may also include a circular polarizer, an additional circular polarizer, and an additional quarter waveplate.
