LIGHT EMITTING DIODE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240260417 titled 'LIGHT EMITTING DIODE DISPLAY DEVICE
The abstract describes a light-emitting display device that includes a bank with an opening corresponding to the emission region of a pixel, an inclined reflective portion in the pixel region, a light-emitting diode with an emission layer and electrodes, and light reflectors with a lower refractive index than the emission layer.
- Bank with opening for emission region
- Inclined reflective portion in pixel region
- Light-emitting diode with emission layer and electrodes
- Light reflectors with lower refractive index
- Circular or elliptical interface between emission layer and bank
- Linear interface between emission layer and light reflector
- Light reflectors in caustic region for total reflection
Potential Applications: - Display screens - Signage - Lighting applications
Problems Solved: - Enhanced light emission efficiency - Improved display quality - Reduced light loss
Benefits: - Brighter displays - Energy-efficient lighting - Enhanced visual experience
Commercial Applications: Title: Advanced Light-Emitting Display Technology for Enhanced Visuals This technology can be utilized in various commercial applications such as high-resolution displays for televisions, smartphones, and digital signage. It can also be integrated into lighting fixtures for energy-efficient and visually appealing illumination solutions.
Questions about the technology: 1. How does the inclined reflective portion contribute to the overall performance of the light-emitting display device?
The inclined reflective portion helps to direct and enhance the light emitted by the light-emitting diode towards the desired viewing angle, improving the overall brightness and clarity of the display.
2. What is the significance of the circular or elliptical interface between the emission layer and the bank in the device?
The circular or elliptical interface ensures a more uniform distribution of light emission from the pixel region, resulting in consistent and high-quality display output.
Original Abstract Submitted
a light emitting display device includes: a bank on a substrate and including an opening which corresponds to an emission region of a pixel region; an inclined reflective portion below the bank and disposed in the pixel region; a light emitting diode at the emission region and including an emission layer and first and second electrodes which are disposed below and on the emission layer, respectively; and a plurality of light reflectors inside the light emitting diode and having a lower refractive index than that of the emission layer, wherein a first interface between the emission layer and the bank is circular or elliptical, and the light reflector forming a second interface with the emission layer is linear, and wherein at least a portion of the light reflector is disposed in a caustic region which is a total reflection optical path region made by total reflection along the first interface.
