==BACKLIGHT AND DISPLAY APPARATUS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240255799 titled 'BACKLIGHT AND DISPLAY APPARATUS

The present invention aims to reduce a yellow shift around blue LEDs in a backlight that includes blue LEDs and a color conversion sheet.

* Blue LEDs are arranged in a matrix on a plane at first intervals.
* A color conversion sheet covers the light source, containing red quantum dots that emit red light in response to blue light and green quantum dots that emit green light in response to blue light.
* Short-wavelength LEDs that emit light of a shorter wavelength than blue light are placed near the blue LEDs.
* Blue quantum dots that emit blue light in response to the short-wavelength light are positioned in the color conversion sheet, overlapping the short-wavelength LEDs in plan view.

Potential Applications:
- This technology can be used in displays, TVs, monitors, and other electronic devices that require backlighting.
- It can also be applied in automotive lighting, signage, and other areas where LED lighting is used.

Problems Solved:
- Reducing the yellow shift around blue LEDs improves the overall color accuracy and quality of the backlight.
- By incorporating quantum dots and short-wavelength LEDs, the technology enhances the efficiency and performance of the backlight.

Benefits:
- Improved color accuracy and vibrancy in displays and lighting systems.
- Enhanced energy efficiency and longevity of LED backlights.
- Reduction of color distortion and yellow tint commonly associated with blue LEDs.

Commercial Applications:
"Advanced LED Backlight Technology for Displays and Lighting Systems"

Questions about LED Backlight Technology:
1. How does the incorporation of quantum dots improve the color accuracy of LED backlights?
2. What are the potential cost implications of implementing this technology in commercial displays and lighting products?

Frequently Updated Research:
Stay updated on the latest advancements in LED backlight technology, quantum dot applications, and display innovations to maximize the benefits of this technology.


==Original Abstract Submitted==

the present invention has been made to reduce a yellow shift around blue leds in a backlight including the blue leds and a color conversion sheet. provided is a backlight including a light source including blue leds arranged in a matrix, on a plane, at first intervals, and a color conversion sheet arranged to cover the light source, in which red quantum dots that emit red light in response to blue light and green quantum dots that emit green light in response to blue light are dispersed in the color conversion sheet, short-wavelength leds that emit light of a shorter wavelength than that of blue light are arranged near the blue leds, and blue quantum dots that emit blue light in response to the short-wavelength light are arranged in the color conversion sheet, at positions overlapping the short-wavelength leds in plan view.
