LIGHT EMITTING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240260416 titled 'LIGHT EMITTING DISPLAY DEVICE
Simplified Explanation: The patent application describes a light emitting display device with subpixels that have a unique shape and include light reflectors to enhance light emission efficiency.
- Each subpixel on the device has an emission region with an n-gonal outer interface.
- A light emitting diode is located at each emission region, containing an emission layer.
- Inside the light emitting diode, there are arc-shaped light reflectors with a lower refractive index than the emission layer.
- The arc-shaped light reflectors are positioned in a quasi-caustic region of the outer interface.
Key Features and Innovation:
- Subpixels with n-gonal outer interfaces for improved light emission.
- Light emitting diodes with emission layers for each subpixel.
- Arc-shaped light reflectors with lower refractive index to enhance light emission efficiency.
- Placement of reflectors in a quasi-caustic region for optimal light reflection.
Potential Applications: This technology can be used in various display devices such as TVs, monitors, and smartphones to improve brightness and color accuracy.
Problems Solved: The technology addresses issues related to light emission efficiency and brightness uniformity in display devices.
Benefits:
- Enhanced light emission efficiency.
- Improved brightness and color accuracy.
- Uniform light distribution across the display.
Commercial Applications: This technology has potential commercial applications in the consumer electronics industry for manufacturing high-quality display devices with improved performance.
