POLARIZER-FREE LED DISPLAYS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240284703 titled 'POLARIZER-FREE LED DISPLAYS

Simplified Explanation: The patent application describes a subpixel structure with a directional light-emitting diode, a lens to focus the emitted light, and a patterned light absorption barrier.

• The directional light-emitting diode emits light with a narrow divergence angle of less than 10 degrees.
• A lens is positioned a specific distance from the LED to focus the light.
• A patterned light absorption barrier, located at another distance from the lens, defines an opening where the focused light converges.

Key Features and Innovation:

• Directional light-emitting diode with narrow divergence angle.
• Lens for focusing emitted light.
• Patterned light absorption barrier with defined opening for converged light.

Potential Applications: The technology can be used in high-resolution displays, augmented reality devices, and medical imaging equipment.

Problems Solved: The subpixel structure addresses issues of light dispersion and inefficient light utilization in display technologies.

Benefits: Improved image quality, increased energy efficiency, and enhanced brightness in display devices.

Commercial Applications: The technology can be applied in high-end televisions, smartphones, and virtual reality headsets, enhancing visual performance and user experience.

Prior Art: Prior research in LED display technologies and optical components may provide insights into similar innovations.

Frequently Updated Research: Ongoing research in LED efficiency, optical materials, and display technologies may impact the development and implementation of this subpixel structure.

Questions about Subpixel Structures: 1. How does the directional light-emitting diode improve display performance? 2. What are the potential challenges in integrating this subpixel structure into existing display technologies?

Original Abstract Submitted

exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (fwhm) of emitted light having a divergence angle of less than or about 10�. the subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. the subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. the patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. the subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.
