U.S. Invents New Way to Improve Green Light Efficiency

A few days ago, researchers at the Rensselaer Polytechnic Institute in the United States discovered that nano-scale etching at the junction of a sapphire substrate and a gallium nitride layer of an LED enables the LED to generate green light, which can greatly improve light extraction, internal efficiency, and light emission. aspect.

Computer monitors and televisions display colors in red, blue, and green. Red and blue LEDs have already achieved high-quality, low-cost production targets. Green LED production technology is therefore a breakthrough that the industry has been seeking.

This technology is based on the most inexpensive sapphire substrate, and will improve the light output of red and blue LEDs, which will surely promote LED development towards high performance and low cost.
